cherry-pick from master: Icf079f5f45b1745a8d54f504e28dbbb52c6f7c96
docs: rewrite resources documentation
Huge overhaul. Includes all new dev guides about how resources are used
on Android and how to provide alternatives, including how to handle
runtime configuration changes (restarts). Plus all new reference
docs for all the resource types (drawables, strings, menus, etc.).

+<p>There are two ways you can reference your resources for use in your application:</p>
+<ul>
+ <li><strong>From your code:</strong> Using an integer from a sub-class in your {@code R} class,
+such as:
+ <p>{@code R.string.hello}</p>
+ <p>You will see Android APIs that accept this kind of resource identifier as a method parameter
+(usually defined as the {@code id} parameter).</p>
+ </li>
+ <li><strong>From another resource:</strong> Using a special XML syntax that corresponds to the
+{@code R} sub-class, such as:
+ <p>{@code @string/hello}</p>
+ <p>You can use this syntax in an XML resource any place where a value is expected that is
+matched by the existing resource. For example, if you need to provide a string in either an XML
+attribute or element value, you can reference a resource instead of providing a hard-coded
+string.</p>
+ </li>
+</ul>
+
+
+
+<h2 id="ResourcesInCode">Accessing Resources in Code </h2>
+
+<p>When your application is compiled, Android generates the {@code R.java} file (inside
+the {@code gen/} directory), which contains resource
+identifiers to all the resources in your {@code res/} directory. For each type of resource, a
+specific subclass is added to the {@code R} class (for example,
+{@code R.drawable}) and for each resource of that type, a static
+integer is added to the subclass (for example,
+{@code R.drawable.icon}). This integer is the resource ID and you can use it to retrieve
+your resource from your application code.</p>
+
+
+<div class="sidebox-wrapper">
+<div class="sidebox">
+<h2>Access to Original Files</h2>
+
+<p>While uncommon, you might need access your original files and directories. If you do, then
+saving your files in {@code res/} won't work for you. Instead, you can save your resources in the
+{@code assets/} directory.</p>
+<p>Files saved in the {@code assets/} directory will <em>not</em> be given a resource
+ID, so you can't reference them through the {@code R} class or from XML resources. Instead, you can
+query files in the {@code assets/} directory like a normal file system and read raw data using
+{@link android.content.res.AssetManager}.</p>
+<p>However, if all you require is the ability to read raw data (such as a video or audio file),
+then save the file in the {@code res/raw/} directory and read a stream of bytes using {@link
+android.content.res.Resources#openRawResource(int)}.</p>
+
+</div>
+</div>
+
+
+<p class="caution"><strong>Caution:</strong> You should never modify the {@code
+R.java} file by hand—it is generated by the {@code aapt} tool when your project is
+compiled. Any changes will be overridden next time you compile.</p>
+
+<p>Here is the syntax to reference a resource in code:</p>
+<p>
+<code>[<em><package_name></em>.]R.<em><resource_type></em>.<em><resource_name></em></code>
+</p>
+
+<ul>
+ <li><em>{@code <package_name>}</em> is the name of the package in which the resource is located (not
+required when referencing resources from your own package).</li>
+ <li><em>{@code <resource_type>}</em> is the {@code R} subclass for the resource type.</li>
+ <li><em>{@code <resource_name>}</em> is either the {@code
+android:name} attribute value (for some resources defined in XML files) or the resource filename
+without the extension.</li>
+</ul>
+<p>See <a href="resource-types.html">Resource Types</a> for
+more information about each resource type and how to reference them.</p>
+
+<p>In many cases, you can supply an API method with the resource ID. For example, to set the image
+for an {@link android.widget.ImageView}:</p>
+<pre>
+ImageView iv = (ImageView) findViewById(R.id.myimageview);
+iv.setImageResource(R.drawable.myimage);
+</pre>
+
+<p>You can also retrieve your
+resource objects using methods in {@link android.content.res.Resources}, which you can create an
+instance of with {@link android.content.Context#getResources Context.getResources()}. For example,
+to get a string:</p>
+<pre>
+Resources res = this.getResources();
+String string = res.getString(R.string.mystring);
+</pre>
+
+<p>You can also access resources from the platform by prefixing the {@code android}
+namespace. Android contains a number of standard resources, such as styles and themes for your
+layout, button backgrounds, and layouts. To refer to these in code, qualify your reference with the
+<code>android</code> package name. For example,
+<code>android.R.layout.simple_gallery_item</code>.</p>
+
+<p>Here are some examples of using resources in code:</p>
+
+<pre>
+// Load a background for the current screen from a drawable resource
+{@link android.app.Activity#getWindow()}.{@link
+android.view.Window#setBackgroundDrawableResource(int)
+setBackgroundDrawableResource}(R.drawable.my_background_image) ;
+
+// Set the Activity title by getting a string from the Resources object, because
+// this method requires a CharSequence rather than a resource ID
+{@link android.app.Activity#getWindow()}.{@link android.view.Window#setTitle(CharSequence)
+setTitle}(getResources().{@link android.content.res.Resources#getText(int)
+getText}(R.string.main_title));
+
+// Load a custom layout for the current screen
+{@link android.app.Activity#setContentView(int)
+setContentView}(R.layout.main_screen);
+
+// Set a slide in animation by getting an Animation from the Resources object
+mFlipper.{@link android.widget.ViewAnimator#setInAnimation(Animation)
+setInAnimation}(AnimationUtils.loadAnimation(this,
+ R.anim.hyperspace_in));
+
+// Set the text on a TextView object using a resource ID
+TextView msgTextView = (TextView) findViewById(R.id.msg);
+msgTextView.{@link android.widget.TextView#setText(int) setText}(R.string.hello_message);
+</pre>
+
+
+
+
+
+
+<h2 id="ReferencesToResources">Accessing Resources in other XML Resources</h2>
+
+<p>When creating an XML resource, some values for attributes and elements can be a reference to
+an existing resource. This is often used in layout files to supply strings and images.</p>
+
+<p>Here is the syntax to reference a resource in an XML resource:</p>
+<p><code>@[<em><package_name></em>:]<em><resource_type></em>/<em><resource_name></em></code></p>
+
+<ul>
+ <li>{@code <package_name>} is the name of the package in which the resource is located (not
+required when referencing resources from the same package)</li>
+ <li>{@code <resource_type>} is the
+{@code R} subclass for the resource type</li>
+ <li>{@code <resource_name>} is either the {@code
+android:name} attribute value (for some resources defined in XML files) or the resource filename
+without the extension</li>
+</ul>
+
+<p>See <a href="resource-types.html">Resource Types</a> for
+more information about each resource type and how to reference them.</p>
+
+<p>For example, if you have the following resource file that includes a <a
+href="more-resources.html#Color">color resource</a> and a <a
+href="string-resource.html">string resource</a>:</p>
+
+<pre>
+<?xml version="1.0" encoding="utf-8"?>
+<resources>
+ <color name="opaque_red">#f00</color>
+ <string name="hello">Hello!</string>
+</resources>
+</pre>
+
+<p>You can use these resources in the following layout file to set the text color and
+text string:</p>
+
+<pre>
+<?xml version="1.0" encoding="utf-8"?>
+<EditText xmlns:android="http://schemas.android.com/apk/res/android"
+ android:layout_width="fill_parent"
+ android:layout_height="fill_parent"
+ <strong>android:textColor="@color/opaque_red"
+ android:text="@string/hello"</strong> />
+</pre>
+
+<p>In this case you don't need to specify the package name in the resource reference because the
+resources are from your own package. To
+reference a system resource, you would need to include the package name. For example:</p>
+
+<pre>
+<?xml version="1.0" encoding="utf-8"?>
+<EditText xmlns:android="http://schemas.android.com/apk/res/android"
+ android:layout_width="fill_parent"
+ android:layout_height="fill_parent"
+ <strong>android:textColor="@android:color/secondary_text_dark"</strong>
+ android:text="@string/hello" />
+</pre>
+
+<p class="note"><strong>Note:</strong> You should always use a string resource when supplying
+strings in a layout file, as demonstrated above, so that the strings can be localized. For
+information about creating alternative resources (such as localized strings), see <a
+href="providing-resources.html#AlternativeResources">Providing Alternative
+Resources</a>.</p>
+
+<p>This facility for referencing resources between resources can also be used to create
+alias resources. For example, you can create new drawable resources that is an alias for an existing
+image:</p>
+
+<pre>
+<?xml version="1.0" encoding="utf-8"?>
+<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
+ android:src="@drawable/other_drawable" />
+</pre>
+
+<p>This is discussed further in <a href="providing-resources.html#AliasResources">Creating
+alias resources</a>.</p>
+
+
+
+
+<h3 id="ReferencesToThemeAttributes">Referencing style attributes</h3>
+
+<p>A style attribute resource is another type of resource that allows you to reference the value
+of an attribute in the currently-applied theme. Referencing a style attribute allows you to
+customize the look of UI elements by styling them to match standard variations supplied by the
+current theme, instead of supplying a hard-coded value. Referencing a style attribute
+essentially says, "use the style that is defined by this attribute, in the current theme."</p>
+
+<p>To reference a style attribute, the name syntax is almost identical to the normal resource
+format, but instead of the at-symbol ({@code @}), use a question-mark ({@code ?}), and the
+resource type portion is optional. For instance:</p>
+
+<p>
+<code>
+?[<em><package_name></em>:][<em><resource_type></em>/]<em><resource_name></em>
+</code>
+</p>
+
+<p>For example, here's how you might reference an attribute in a layout,
+to set the text color to match the "primary" text color of the system theme:</p>
+
+<pre>
+<EditText id="text"
+ android:layout_width="fill_parent"
+ android:layout_height="wrap_content"
+ <strong>android:textColor="?android:textColorSecondary"</strong>
+ android:text="@string/hello_world" />
+</pre>
+
+<p>Using this markup, you are
+supplying the name of an attribute resource that will be looked up in the theme.
+Because the system resource tool knows that an attribute resource is expected,
+you do not need to explicitly state the type (which would be
+<code>?android:attr/textColorSecondary</code>), so you can exclude the {@code attr} type.</p>

+<h3 id="Interpolators">Interpolators</h3>
+
+<p>An interpolator is an animation modifier defined in XML that affects the rate of change in an
+animation. This allows your existing animation effects to be accelerated, decelerated, repeated,
+bounced, etc.</p>
+
+<p>An interpolator is applied to an animation element with the {@code android:interpolator}
+attribute, the value of which is a reference to an interpolator resource.</p>
+
+<p>All interpolators available in Android are subclasses of the {@link
+android.view.animation.Interpolator} class. For each interpolator class, Android
+includes a public resource you can reference in order to apply the interpolator to an animation
+using the the {@code android:interpolator} attribute.
+The following table specifies the resource to use for each interpolator:</p>
+
+<table>
+ <tr><th>Interpolator class</th><th>Resource ID</th></tr>
+ <tr>
+ <td>{@link android.view.animation.AccelerateDecelerateInterpolator}</td>
+ <td>{@code @android:anim/accelerate_decelerate_interpolator}</td>
+ </tr>
+ <tr>
+ <td>{@link android.view.animation.AccelerateInterpolator}</td>
+ <td>{@code @android:anim/accelerate_interpolator}</td>
+ </tr>
+ <tr>
+ <td>{@link android.view.animation.AnticipateInterpolator}</td>
+ <td>{@code @android:anim/anticipate_interpolator}</td>
+ </tr>
+ <tr>
+ <td>{@link android.view.animation.AnticipateOvershootInterpolator}</td>
+ <td>{@code @android:anim/anticipate_overshoot_interpolator}</td>
+ </tr>
+ <tr>
+ <td>{@link android.view.animation.BounceInterpolator}</td>
+ <td>{@code @android:anim/bounce_interpolator}</td>
+ </tr>
+ <tr>
+ <td>{@link android.view.animation.CycleInterpolator}</td>
+ <td>{@code @android:anim/cycle_interpolator}</td>

+</pre>
+
+
+<h4>Custom interpolators</h4>
+
+<p>If you're not satisfied with the interpolators provided by the platform (listed in the
+table above), you can create a custom interpolator resource with modified attributes.
+For example, you can adjust the rate of
+acceleration for the {@link android.view.animation.AnticipateInterpolator}, or adjust the number of
+cycles for the {@link android.view.animation.CycleInterpolator}. In order to do so, you need to
+create your own interpolator resource in an XML file.

-<p>This page describes the different types of resources that you can
-externalize from your code and package with your application. </p>
+<p>Each of the documents in this section describe the usage, format and syntax for a certain type
+of application resource that you can provide in your resources directory ({@code res/}).</p>
-
-<p>For more details on how to use resources in your application, please see the
- <a href="resources-i18n.html">Resources and Internationalization</a>
- documentation.</p>
-
-
-<h2 id="simplevalues">Simple Values</h2>
-
-<p>All simple resource values can be expressed as a string, using various
-formats to unambiguously indicate the type of resource being created. For
-this reason, these values can be defined both as standard resources
-(under res/values/), as well as direct values supplied for
-mappings in <a href="#stylesandthemes">styles and themes</a>, and attributes in
-XML files such as <a href="#layoutresources">layouts</a>.</p>
-
-
-
-<h3 id="colorvals">Color Values</h3>
-<p>
- A color value specifies an RGB value with an alpha channel, which can
- be used in various places such as specifying a solid color for a {@link android.graphics.drawable.Drawable}
- or the color to use for text. A color value always begins with
- a pound (#) character and then followed by the Alpha-Red-Green-Blue information
- in one of the following formats:
-</p>
-<ul>
-<li> #RGB
-<li> #ARGB
-<li> #RRGGBB
-<li> #AARRGGBB
-</ul>
-<p>
- If you want to retrieve the color represented by a resource ID, you can call
- the {@link android.content.res.Resources#getColor(int) Resources.getColor()} method.
-</p>
-<p>
- <strong>Source file format:</strong> XML file requiring a
- <code><?xml version="1.0" encoding="utf-8"?></code> declaration, and
- a root <code><resources></code> element containing one or more
- <code><color></code> tags.
-</p>
-<p>
- <strong>Resource source file location</strong>: {@code res/values/<em>colors</em>.xml} (File name is arbitrary.)
-</p>
-<p>
- <strong>Compiled resource datatype:</strong> Resource pointer to a Java int.
-</p>
-<p>
- <strong>Resource reference name:</strong>

-
-<h3 id="stringresources">Strings and Styled Text</h3>
-<p>
- Strings, with optional <a href="#styledtext">simple formatting</a>, can be
-stored and retrieved as resources. You can add formatting to your string by
-using three standard HTML tags: <b>, <i>, and <u>. To
-guarantee getting an unstyled string only (the raw text) call the
-<code>toString()</code> method of the retrieved CharSequence object.
-Methods that accept string resources should be able to process these styling
-tags.
-</p>
-<p>
- If you want to retrieve the String represented by a resource ID, you can call the {@link android.content.Context#getString(int) Context.getString()} method.
-</p>
-<p>
- <strong>Note:</strong> If you use an apostrophe or a quote in your string, you must either escape it or enclose the whole string in the other kind of enclosing quotes:
-</p>
-<pre>
-<string name="good_example">"This'll work"</string>
-<string name="good_example_2">This\'ll also work</string>
-<string name="bad_example">This won't work!</string>
-<string name="bad_example_2">XML encodings won&apos;t work either!</string>
-</pre>
-<p>
- <strong>Source file format:</strong> XML file requiring a <code><?xml version="1.0" encoding="utf-8"?></code> declaration, and a root <code><resources></code> element containing one or more <code><string></code> tags.
-</p>
-<p>
- <strong>Resource source file location</strong>: {@code res/values/<em>strings</em>.xml} (File name is arbitrary.)
-</p>
-<p>
- <strong>Compiled resource datatype:</strong> Resource pointer to a Java CharSequence.
-</p>
-<p>
- <strong>Resource reference name:</strong>

- Value is a string, with optional styling tags. Has only one attribute:
- <ul>
- <li>
- <em>name</em> - The name used in referring to this string.
- </li>
- </ul>
- </dd>
-</dl>
-<p>
- <strong>Example XML Declaration</strong>
-</p>
-<p>
- The following declares two strings: the first — simple text with no
- formatting (resulting in a CharSequence that is simply a String object) — the second includes formatting information in the string (resulting
- in a CharSequence that is a complex data structure). If you are using the custom editor for string files in Eclipse, the HTML formatting tags will automatically be escaped and you will need to use {@link android.content.Context#getString(int) Context.getString()} and {@link android.text.Html#fromHtml} to retrieve the resource and then convert it to formatted text.
-</p>
-<pre>
-<resources>
- <string name="simple_welcome_message">Welcome!</string>
- <string name="styled_welcome_message">We are <b><i>so</i></b> glad to see you.</string>
-</resources>
-</pre>
-<p>
- <strong>Example Code Use</strong>
-</p>
-<p>
- Example Java code
-</p>
-<pre>
-// Assign a styled string resource to a TextView
-// on the current screen.
-CharSequence str = getString(R.string.styled_welcome_message);
-TextView tv = (TextView)findViewByID(R.id.text);
-tv.setText(str);
-</pre>
-<p>
- Example XML code
-</p>
-<pre>
-<TextView android:layout_width="fill_parent"
- android:layout_height="wrap_content"
- android:textAlign="center"
- android:text="@string/simple_welcome_message"/>
-</pre>
-
-
-<h4 id="styledtext">Using Styled Text as a Format String</h4>
-<p>
-Sometimes you may want to create a styled text resource that is also used as a
-format string. This cannot be done directly because there is no way of passing
-the styled text as the format string argument of String.format()
-without stripping out the style information. The workaround is to store the
-style tags as escaped HTML tags, and then convert the escaped HTML string into
-a styled text after formatting has taken place.
-</p>
-<p>
-To use styled text as a format string, do the following.
-</p>
-<ol>
- <li>Store your styled text resource as an escaped string, so that the HTML tags in your text resource are not interpreted as if they were XML tags:
-<pre>
-<resources>
- <string name="search_results_resultsTextFormat">%1$d results for &lt;b>&amp;quot;%2$s&amp;quot;&lt;/b></string>
-</resources>
-</pre>
-<p>
-In this example the format string has two arguments: <code>%1$d</code> is a decimal number, <code>%2$s</code> is a string.
-</p>
-</li>
-<li>
- Make sure any String arguments are properly escaped if they might contain '<' or '&' characters.
-The {@link android.text.TextUtils#htmlEncode} method will do this:
-<pre>
-String escapedTitle = TextUtil.htmlEncode(title);
-</pre>
-</li>
-<li>
- Use String.format() to format the HTML text, then use {@link android.text.Html#fromHtml} to convert the HTML text into styled text:
-<pre>
-String resultsTextFormat = getContext().getResources().getString(R.string.search_results_resultsTextFormat);
-String resultsText = String.format(resultsTextFormat, count, escapedTitle);
-CharSequence styledResults = Html.fromHtml(resultsText);
-</pre>
-</li>
-</ol>
-
-
-<h3 id="dimension"Dimension Values</h3>
-<p>You can create common dimensions to use for various screen elements by
-defining dimension values in XML. A dimension resource is a number followed by
-a unit of measurement. For example: 10px, 2in, 5sp. Here are the units of
-measurement supported by Android:</p>
-<dl>
- <dt>px</dt>
- <dd>Pixels - corresponds to actual pixels on the screen.</dd>
-
- <dt>in</dt>
- <dd>Inches - based on the physical size of the screen.</dd>
-
- <dt>mm</dt>
- <dd>Millimeters - based on the physical size of the screen.</dd>

-<h2 id="layoutresources">Layout</h2>
-<p>Android lets you specify screen layouts using XML elements inside an XML
-file, similar to designing screen layout for a webpage in an HTML file. Each
-file contains a whole screen or a part of a screen, and is compiled into a
-View resource that can be passed in to
-{@link android.app.Activity#setContentView(int) Activity.setContentView} or used as a
-reference by other layout resource elements. Files are saved in the
-<code>res/layout/</code> folder of your project, and compiled by the Android resource
-compiler, aapt. </p>
-
-<p> Every layout XML file must evaluate to a single root
-element. First we'll describe how to use the standard XML tags understood by
-Android as it is shipped, and then we'll give a little information on how you
-can define your own custom XML elements for custom View objects.
-
-<p> The root element must have
-the Android namespace "http://schemas.android.com/apk/res/android" defined in
-the root element.</p>
-
-<p>For a complete discussion on creating layouts, see the
-<a href="{@docRoot}guide/topics/ui/index.html">User Interface</a> topic.</p>

- </dt>
- <dd>
- <p>The file must have a single root element. This can be a ViewGroup class that contains other elements, or a widget (or custom item) if it's only one object. By default, you can use any (case-sensitive) Android {@link android.widget widget} or {@link android.view.ViewGroup ViewGroup} class name as an element. These elements support attributes that apply to the underlying class, but the naming is not as clear. How to discover what attributes are supported for what tags is discussed below. You should not assume that any nesting is valid (for example you cannot enclose <code><TextView></code> elements inside a <code><ListLayout></code>).</p>
- <p>If a class derives from another class, the XML element inherits all the attributes from the element that it "derives" from. So, for example, <code><EditText></code> is the corresponding XML element for the EditText class. It exposes its own unique attributes (<code>EditText_numeric</code>), as well as all attributes supported by <code><TextView></code> and <code><View></code>. For the <em>id</em> attribute of a tag in XML, you should use a special syntax: "@+id/<em>somestringvalue</em>". The "@+" syntax creates a resource number in the R.id class, if one doesn't exist, or uses it, if it does exist. When declaring an ID value for an XML tag, use this syntax. Example: <code><TextView android:id="@+id/nameTextbox"/></code>, and refer to it this way in Java: <code>findViewById(R.id.nameTextbox)</code>. All elements support the following values:</p>
- <ul>
- <li>
- <em>id</em> - An ID value used to access this element in Java. Typically you will use the syntax @+id/<em>string_name</em> to generate an ID for you in the id.xml file if you haven't created one yourself.
- </li>
- <li>
- <code>xmlns:android="http://schemas.android.com/apk/res/android"</code> - <em><strong>Required for the root element only.</strong></em>
- </li>
- </ul>
- </dd>
- <dt>
- <requestFocus>
- </dt>
- <dd>
- Any element representing a View object can include this empty element, which gives it's parent tag initial focus on the screen. You can have only one of these elements per file.
- </dd>
-</dl>
-<p>
- <strong>What Attributes Are Supported for What Elements?</strong>
-</p>
-<p>
- Android uses the {@link android.view.LayoutInflater} class at run time to load an XML layout resource and translate it into visual elements. By default, all widget class names are supported directly as tags, but a full list of supported tags and attributes is listed in the {@link android.R.styleable} reference page. However, the attribute names are somewhat obscure. If an underscore appears in the name, this indicates that it is an attribute — typically of the element before the underscore. So, for example, <code>EditText_autoText</code> means that the <code><EditText></code> tag supports an attribute <em>autoText</em>. When you actually use the attribute in that element, use only the portion after the last underscore, and prefix the attribute with the prefix "<code>android:</code>". So, for example, if {@link android.R.styleable} lists the following values:
-</p>
-<ul>
- <li>
- <code>TextView</code>
- </li>
- <li>
- <code>TextView_lines</code>
- </li>
- <li>
- <code>TextView_maxlines</code>
- </li>
-</ul>
-<p>
- You could create an element like this:
-</p>
-<pre>
-<TextView android:lines="10" android:maxlines="20"/>
-</pre>
-<p>
- This would create a {@link android.widget.TextView} object and set its lines and maxlines properties.
-</p>
-<p>
- Attributes come from three sources:
-</p>
-<ul>
- <li>
- <strong>Attributes exposed directly by the element.</strong> For example, <code>TextView</code> supports <code>TextView_text</code>, as discussed above.
- </li>
- <li>
- <strong>Attributes exposed by all the superclasses of that element.</strong> For example, the TextView class extends the View class, so the <code><TextView></code> element supports all the attributes that the <code><View></code> element exposes — a long list, including <code>View_paddingBottom</code> and <code>View_scrollbars</code>. These too are used without the class name: <code><TextView android:paddingBottom="20" android:scrollbars="horizontal" /></code>.
- </li>
- <li>
- <strong>Attributes of the object's {@link android.view.ViewGroup.LayoutParams} subclass.</strong> All View objects support a LayoutParams member (see <a href="{@docRoot}guide/topics/ui/declaring-layout.html#layout-params">Declaring Layout</a>). To set properties on an element's LayoutParams member, the attribute to use is "android:layout_<em>layoutParamsProperty</em>". For example: <code>android:layout_gravity</code> for an object wrapped by a <code><LinearLayout></code> element. Remember that each LayoutParams subclass also supports inherited attributes. Attributes exposed by each subclass are given in the format <em>someLayoutParamsSubclass</em>_Layout_layout_<em>someproperty</em>. This defines an attribute "android:layout_<em>someproperty</em>". Here is an example of how Android documentation lists the properties of the {@link android.widget.LinearLayout.LayoutParams LinearLayout.LayoutParams} class:
- </li>
-</ul>
-<ul>
- <li>LinearLayout_Layout // The actual object — not used.
- </li>
- <li>LinearLayout_Layout_layout_gravity // Exposes a <code>gravity</code> attribute
- </li>
- <li>LinearLayout_Layout_layout_height // Exposes a <code>height</code> attribute
- </li>
- <li>LinearLayout_Layout_layout_weight // Exposes a <code>weight</code> attribute
- </li>
- <li>LinearLayout_Layout_layout_width // Exposes a <code>width</code> attribute
- </li>
-</ul>
-<p>
- Here is an example that sets some of these values on a few objects, including direct attributes, inherited attributes, and LayoutParams attributes:
-</p>
-<pre>
-<?xml version="1.0" encoding="utf-8"?>
-<!-- res/main_screen.xml -->
-<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
- android:orientation="vertical" // The object's own orientation property
- android:padding="4" // Inherited View property
- android:gravity="center" // The object's own property
- android:layout_width="fill_parent" // Parent object's LinearLayout.LayoutParams.width
- android:layout_height="fill_parent"> // Parent object's LinearLayout.LayoutParams.height
-
- <TextView android:layout_width="fill_parent" // TextView.LayoutParams.width
- android:layout_height="wrap_content" // TextView.LayoutParams.height
- android:layout_weight="0" // TextView.LayoutParams.weight
- android:paddingBottom="4" // TextView.paddingBottom
- android:text="@string/redirect_getter"/> // TextView.text
-
- <EditText android:id="@+id/text"
- android:layout_width="fill_parent" // EditText.LayoutParams.width
- android:layout_height="wrap_content" // EditText.LayoutParams.height
- android:layout_weight="0" // EditText.LinearLayoutParams.weight
- android:paddingBottom="4"> // EditText.paddingBottom
- <requestFocus />
- </EditText>
-
- <Button android:id="@+id/apply"
- android:layout_width="wrap_content" // Button.LayoutParams.width
- android:layout_height="wrap_content" // Button.LayoutParams.height
- android:text="@string/apply" /> // TextView.text
-</LinearLayout>
-</pre>
-<p>
- <strong>Example Code Use</strong>
-</p>
-<p>
- The most common use is to load the XML file (located at <em>res/main_screen.xml</em>) and use it as the current screen, as shown here with the preceding file:
-</p>
-<pre>
-setContentView(R.layout.main_screen);
-</pre>
-<p>
- However, layout elements can also represent repeating elements used as templates.
-</p>
-
-<p>Also see <a href="{@docRoot}guide/topics/ui/index.html">User Interface</a> for more information on layouts.</p>

-<h3 id="customresources">Custom Layout Resources</h3>
-<p>
- You can define custom elements to use in layout resources. These custom elements can then be used the same as any Android layout elements: that is, you can use them and specify their attributes in other resources. The ApiDemos sample application has an example of creating a custom layout XML tag, LabelView. To create a custom element, you will need the following files:
-</p>
-<ul>
- <li>
- <strong>Java implementation file</strong> - The implementation file. The class must extend {@link android.view.View View} or a subclass. See LabelView.java in ApiDemos.
- </li>
- <li>
- <strong>res/values/attrs.xml</strong> - Defines the XML element, and the attributes that it supports, for clients to use to instantiate your object in their layout XML file. Define your element in a <code><declare-styleable name=<em>your_java_class_name</em>></code>. See res/values/attrs.xml in ApiDemos.
- </li>
- <li>
- <strong>res/layout/<em>your_class</em>.xml</strong> [<em>optional</em>] - An optional XML file to describe the layout of your object. This could also be done in Java. See custom_view_1.xml in ApiDemos.
- </li>
-</ul>
-<p>
- <strong>Source file format:</strong> XML file without an <code><?xml></code> declaration, and a <code><resources></code> root element containing one or more custom element tags.
-</p>
-<p>
- <strong>Resource file location</strong>: {@code res/values/<em>attrs</em>.xml} (File name is arbitrary.)
-</p>
-<p>
- <strong>Compiled resource datatype:</strong> Resource pointer to a {@link android.view.View} (or subclass) resource.
-</p>
-<p>
- <strong>Resource reference name:</strong> R.styleable.<em>some_file</em> (Java).
-</p>
-
-
-
-<h2 id="stylesandthemes">Styles and Themes</h2>
-<p>
- A <em>style</em> is one or more attributes applied to a single element (for example, 10 point red Arial font, applied to a TextView). A style is applied as an attribute to an element in a layout XML file.
-</p>
-<p>
- A <em>theme</em> is one or more attributes applied to a whole screen — for example, you might apply the stock Android Theme.dialog theme to an activity designed to be a floating dialog box. A theme is assigned as an attribute to an Activity in the manifest file.
-</p>
-<p>
- Both styles and themes are defined in a <code><style></code> block containing one or more string or numerical values (typically color values), or references to other resources (drawables and so on). These elements support inheritance, so you could have MyBaseTheme, MyBaseTheme.Fancy, MyBaseTheme.Small, and so on.
-</p>
-
-<p>For a complete discussion on styles and themes, read
-<a href="{@docRoot}guide/topics/ui/themes.html">Applying Styles and Themes</a>.</p>
-
-<p>
- <strong>Source file format:</strong> XML file requiring a <code><?xml version="1.0" encoding="utf-8"?></code> declaration, and a root <code><resources></code> element containing one or more <code><style></code> tags.
-</p>
-<p>
- <strong>Resource source file location</strong>: {@code res/values/styles.xml} (File name is arbitrary, but standard practice is to put all styles into a file named styles.xml.)
-</p>
-<p>
- <strong>Compiled resource datatype:</strong> Resource pointer to a Java CharSequence.
-</p>
-<p>
- <strong>Resource reference name:</strong>
-</p>
-<ul>
- <li>
- <strong>Java:</strong> <code>R.style.<em>styleID</em></code> for the whole style, <code>R.style.<em>styleID</em>.<em>itemID</em></code> for an individual setting
- </li>
- <li>
- <strong>XML:</strong> <code>@[<em>package</em>:]style/<em>styleID</em></code> for a whole style, <code>@[<em>package</em>:]style/<em>styleID</em>/<em>itemID</em></code> for an individual item. <strong>Note</strong>: to refer to a value in the <em>currently</em> applied theme, use "?" instead of "@" as described below (XML).
- </li>
-</ul>
-<p>
- <strong>Syntax</strong>
-</p>
-<pre>
-<style name=<em>string</em> [parent=<em>string</em>] >
- <item name=<em>string</em>><em>Hex value | string value | reference</em></item>+<em>
-</em></style>
-</pre>
-<dl>
- <dt>
- <style>
- </dt>
- <dd>
- Holds one or more <item> elements, each describing one value. This style, which is a bundle of values, can be referred to as a <em>theme</em>.
- <ul>
- <li>
- <em>name</em> - The name used in referring to this theme.
- </li>
- <li>
- <em>parent</em> - An optional parent theme. All values from the specified theme will be inherited into this theme. Any values with identical names that you specify will override inherited values. The name must be qualified by the package, but you don't need the /style directive (for example, <code>android:Theme</code> for the base Android theme, or <code>MyTheme</code> for a theme defined in your package).
- </li>
- </ul>
- </dd>
- <dt>
- <item>
- </dt>
- <dd>
- A value to use in this theme. It can be a standard string, a hex color value, or a reference to any other resource type.
- </dd>

-<h2 id="Searchable">Searchable</h2>
-
-<p>To make search appear to the user as a seamless system-wide feature, the Android framework
-offers APIs that let applications control how they are searched.
-Applications can customize how search is invoked, how the search dialog looks, and what type of
-search results are available, including suggestions that are shown as the user types.</p>
-
-<p>In order to utilize the Android search framework, an application must provide a search configuration
-in the form of an XML resource.
-This section describes the search configuration XML in terms of its syntax and usage. For a more
-complete discussion about how to implement search features for your application, see
-<!-- <a href="{@docRoot}guide/topics/search/index.html">Search</a> -->
-{@link android.app.SearchManager}.</p>
-
-<p>
- <strong>Source file format:</strong>
- XML file requiring a <code><?xml version="1.0" encoding="utf-8"?></code>
- declaration, and a root <code><searchable></code> element.
-</p>
-
-<p>
- <strong>Resource source file location</strong>: {@code res/xml/searchable.xml}
- (The file name is arbitrary, but standard practice is to use searchable.xml.)

-</searchable>
-</pre>
+<p>Here's a brief summary of each resource type:</p>
<dl>
- <dt>
- <searchable>
- </dt>
- <dd>
- Defines all application search configurations, including settings for text and voice searches
- performed within the application. It accepts the following attributes:
- <ul>
- <li>
- <em>label</em> - <strong>Required</strong>. This is the name for your application, as it
- will appear to the user. This will be visible only if <em>searchMode</em> is set to
- "showSearchLabelAsBadge" (see below).
- </li>
- <li>
- <em>hint</em> - This is the text to display in the search text field when no text has
- been entered. This is recommended in order to provide context to the search about to be
- performed (e.g., "Search the Dictionary").
- </li>
- <li>
- <em>searchMode</em> - If provided and non-zero, this sets additional modes for control
- of the search presentation. The following mode values are accepted:
- <ul>
- <li>
- <em>showSearchLabelAsBadge</em> - If set, this enables the display of the
- search target (label) within the search bar.
- </li>
- <li>
- <em>queryRewriteFromData</em> - If set, this causes the suggestion column
- SUGGEST_COLUMN_INTENT_DATA to be considered as the text for suggestion query
- rewriting. This should only be used when the values in
- SUGGEST_COLUMN_INTENT_DATA are suitable for user inspection and editing -
- typically, HTTP/HTTPS Uri's.
- </li>
- <li>
- <em>queryRewriteFromText</em> - If set, this causes the suggestion
- column SUGGEST_COLUMN_TEXT_1 to be considered as the text for suggestion query
- rewriting. This should be used for suggestions in which no query
- text is provided and the SUGGEST_COLUMN_INTENT_DATA values are not suitable
- for user inspection and editing.
- </li>
- </ul>
- <p>More than one of the above values for <em>searchMode</em> can be used at once. For
- example, you can declare two modes at once, like this:
- <code>searchMode="queryRewriteFromData|queryRewriteFromText"</code>
- </li>
- <li>
- <em>inputType</em> - If provided, supplies a hint about the type of search text
- the user will be entering. For most searches, in which free form text is expected,
- this attribute is not needed. See
- {@link android.R.attr#inputType} for a list of suitable values for this attribute.
- </li>
- <li>
- <em>imeOptions</em> - If provided, supplies additional options for the input method.
- For most searches, in which free form text is expected, this attribute is not needed,
- and will default to "actionSearch". See
- {@link android.R.attr#imeOptions} for a list of suitable values for this attribute.
- </li>
- </ul>
-
- <p>If you have defined a content provider to generate search suggestions, you need to
- provide some more searchable metadata in order to configure communications with the content
- provider. The following are additional {@code <searchable>} attributes for use when
- providing search suggestions:</p>
-
- <ul>
- <li>
- <em>searchSuggestAuthority</em> - <strong>Required to provide search suggestions</strong>.
- This value must match the authority string provided in the provider section of your manifest.
- </li>
- <li>
- <em>searchSuggestPath</em> - If provided, this path will be inserted in the suggestions
- query Uri, after the authority you have provide but before the standard suggestions path.
- This is only required if you have a single content provider issuing different types
- of suggestions (e.g. for different data types) and you need
- a way to disambiguate the suggestions queries when they are received.
- </li>
- <li>
- <em>searchSuggestSelection</em> - If provided, this value will be passed into your
- query function as the selection parameter. Typically this will be a WHERE clause for
- your database, and will contain a single question mark, which represents the actual query
- string that has been typed by the user. However, you can also use any non-null value to simply
- trigger the delivery of the query text (via selection arguments), and then use the query
- text in any way appropriate for your provider (ignoring the actual text of the selection parameter.)
- </li>
- <li>
- <em>searchSuggestIntentAction</em> - The default Intent action to be used when a user
- clicks on a search suggestion.
- If provided, and not overridden by the selected suggestion, this value will
- be placed in the action field of the {@link android.content.Intent} when the
- user clicks a suggestion.
- </li>
- <li>
- <em>searchSuggestIntentData</em> - The default Intent data to be used when a user
- clicks on a search suggestion.
- If provided, and not overridden by the selected suggestion, this value will be
- placed in the data field of the {@link android.content.Intent} when the user clicks
- a suggestion.
- </li>
- </ul>
-
- <p>Beyond providing search suggestions while using your application's local search, you
- can also configure your search suggestions to be made available to Quick Search Box,
- which will allow users so receive search suggestions from your application content from outside
- your application. The following are additional {@code <searchable>} attributes for use when
- providing search suggestions to Quick Search Box:</p>
-
- <ul>
- <li>
- <em>includeInGlobalSearch</em> - <strong>Required to provide search suggestions in
- Quick Search Box</strong>. If true, this indicates the search suggestions provided by your
- application should be included in the globally accessible Quick Search Box. The user must
- still enable your application as a searchable item in the system search settings in order
- for your suggestions to appear in Quick Search Box.
- </li>
- <li>
- <em>searchSettingsDescription</em> - If provided, this provides a brief description
- of the search suggestions that you provide to Quick Search Box,
- and will be displayed in the search settings entry for your application.
- </li>
- <li>
- <em>queryAfterZeroResults</em> - Indicates whether a source should be invoked for
- supersets of queries it has returned zero results for in the past. For example, if a
- source returned zero results for "bo", it would be ignored for "bob". If set to false,
- this source will only be ignored for a single session; the next time the search dialog
- is invoked, all sources will be queried. The default value is false.
- </li>
- <li>
- <em>searchSuggestThreshold</em> - Indicates the minimum number of characters needed to
- trigger a source lookup from Quick Search Box. Only guarantees that a source will not be
- queried for anything shorter than the threshold. The default value is 0.
- </li>
- </ul>
-
- <p>To enable voice search for your Activity, you can add fields to the searchable metadata
- that enable and configure voice search. The following are additional {@code <searchable>}
- attributes for use when implementing voice search:</p>
-
- <ul>
- <li>
- <em>voiceSearchMode</em> - <strong>Required to provide voice search
- capabilities</strong>.
- If provided and non-zero, enables voice search.
- (Voice search may not be provided by the device, in which case these flags will
- have no effect.) The following mode values are accepted:
- <ul>
- <li>
- <em>showVoiceSearchButton</em> - If set, display a voice search button. This only
- takes effect if voice search is available on the device. If set, then "launchWebSearch"
- or "launchRecognizer" must also be set.
- </li>
- <li>
- <em>launchWebSearch</em> - If set, the voice search button will take the user directly
- to a built-in voice web search activity. Most applications will not use this flag, as
- it will take the user away from the activity in which search was invoked.
- </li>
- <li>
- <em>launchRecognizer</em> - If set, the voice search button will take
- the user directly to a built-in voice recording activity. This activity
- will prompt the user to speak, transcribe the spoken text, and forward the resulting
- query text to the searchable activity, just as if the user had typed it into the
- search UI and clicked the search button.
- </li>
- </ul>
- </li>
- <li>
- <em>voiceLanguageModel</em> - A string constant from
- {@link android.speech.RecognizerIntent}.
- If provided, this specifies the language model that
- should be used by the voice recognition system. See
- {@link android.speech.RecognizerIntent#EXTRA_LANGUAGE_MODEL } for more
- information. If not provided, the default value
- {@link android.speech.RecognizerIntent#LANGUAGE_MODEL_FREE_FORM } will be used.
- </li>
- <li>
- <em>voicePromptText</em> - A string. If provided, this specifies a prompt
- that will be displayed during voice input. If not provided, a default prompt
- will be displayed.
- </li>
- <li>
- <em>voiceLanguage</em> - A string constant from {@link java.util.Locale}.
- If provided, this specifies the spoken language to be expected.
- This is only needed if it is different from the current value of
- {@link java.util.Locale#getDefault()}.
- </li>
- <li>
- <em>voiceMaxResults</em> - If provided, enforces the maximum number of results to return,
- including the "best" result which will always be provided as the SEARCH intent's primary
- query. Must be one or greater. Use EXTRA_RESULTS to get the results from the intent.
- If not provided, the recognizer will choose how many results to return.
- </li>
- </ul>
- </dd>
-
- <dt>
- <actionkey>
- </dt>
- <dd>
- Defines a shortcut key for a search action.
- <ul>
- <li>
- <em>keycode</em> - <strong>Required</strong>. This attribute denotes the action key
- you wish to respond to. Note that not all action keys are actually supported using
- this mechanism, as many of them are used for typing,
- navigation, or system functions. This will be added to the
- {@link android.content.Intent#ACTION_SEARCH ACTION_SEARCH} Intent that is passed to your
- searchable Activity. To examine the key code, use
- {@link android.content.Intent#getIntExtra getIntExtra(SearchManager.ACTION_KEY)}.
- Note that, in addition to the keycode, you must also provide one or more of
- the action specifier attributes below.
- </li>
- <li>
- <em>queryActionMsg</em> - If you wish to handle an action key during normal
- search query entry, you must define an action string here. This will be added to the
- {@link android.content.Intent#ACTION_SEARCH ACTION_SEARCH} Intent that is
- passed to your searchable Activity. To examine the string, use
- {@link android.content.Intent#getStringExtra
- getStringExtra(SearchManager.ACTION_MSG)}.
- </li>
- <li>
- <em>suggestActionMsg</em> - If you wish to handle an action key while a
- suggestion is being displayed and selected, there are two ways to handle this.
- If all of your suggestions can handle the action key, you can simply define
- the action message using this attribute. This will be added to the
- {@link android.content.Intent#ACTION_SEARCH} Intent that is passed to your
- searchable Activity. To examine the string,
- use {@link android.content.Intent#getStringExtra
- getStringExtra(SearchManager.ACTION_MSG)}.
- </li>
- <li>
- <em>suggestActionMsgColumn</em> - If you wish to handle an action key while
- a suggestion is being displayed and selected, but you do not wish to enable
- this action key for every suggestion, then you can use this attribute to control
- it on a suggestion-by-suggestion basis. First, you must define a column
- (and name it here) where your suggestions will include the action string. Then,
- in your content provider, you must provide this column, and when desired,
- provide data in this column. The search manager will look at your suggestion cursor,
- using the string provided here in order to select a column, and will use
- that to select a string from the cursor. That string will be added to the
- {@link android.content.Intent#ACTION_SEARCH ACTION_SEARCH}
- Intent that is passed to your searchable Activity. To examine
- the string, use {@link android.content.Intent#getStringExtra
- getStringExtra(SearchManager.ACTION_MSG)}. If the data does not exist for the
- selection suggestion, the action key will be ignored.

+<p>A {@link android.content.res.ColorStateList} is an object you can define in XML
+that you can apply as a color, but will actually change colors, depending on the state of
+the {@link android.view.View} object to which it is applied. For example, a {@link
+android.widget.Button} widget can exist in one of several different states (pressed, focused,
+or niether) and, using a color state list, you can provide a different color during each state.</p>
+
+<p>You can describe the state list in an XML file. Each color is defined in an {@code
+<item>} element inside a single {@code <selector>} element. Each {@code <item>}
+uses various attributes to describe the state in which it should be used.</p>
+
+<p>During each state change, the state list is traversed top to bottom and the first item that
+matches the current state will be used—the selection is <em>not</em> based on the "best
+match," but simply the first item that meets the minimum criteria of the state.</p>
+

+<p>A drawable resource is a general concept for a graphic that you
+can retrieve with {@link android.content.res.Resources#getDrawable(int)}
+and draw on the screen. There are several different types of drawables:</p>
+<dl>
+ <dt><a href="#Bitmap">Bitmap File</a><dt>
+ <dd>A bitmap graphic file ({@code .png}, {@code .jpg}, or {@code .gif}).
+ A {@link android.graphics.drawable.BitmapDrawable}.</dd>
+ <dt><a href="#NinePatch">Nine-Patch File</a></dt>
+ <dd>A PNG file with stretchable regions to allow image resizing based on content ({@code
+.9.png}). A {@link android.graphics.drawable.NinePatchDrawable}.</dd>
+<!-- <dt><a href="#BitmapAlias">Bitmap Alias</a><dt>
+ <dd>An alias for a drawable.</dd> -->
+ <dt><a href="#StateList">State List</a></dt>
+ <dd>An XML file that references different bitmap graphics
+ for different states (for example, to use a different image when a button is pressed).
+ A {@link android.graphics.drawable.StateListDrawable}.</dd>
+ <dt><a href="#Color">Color</a></dt>
+ <dd>A resource defined in XML that specifies a rectangle of color, with
+ optionally rounded corners. A {@link android.graphics.drawable.PaintDrawable}.</dd>
+ <dt><a href="#Shape">Shape</a></dt>
+ <dd>An XML file that defines a geometric shape, including colors and gradients.
+ A {@link android.graphics.drawable.ShapeDrawable}.</dd>
+</dl>
+
+<p>Documentation for the {@link android.graphics.drawable.AnimationDrawable} resource
+is in the <a href="animation-resource.html">Animation Resource</a> document.</p>
+
+<h2 id="Bitmap">Bitmap File</h2>
+
+<p>A basic bitmap image. Android supports basic bitmap files in a few different formats:
+{@code .png} (preferred), {@code .jpg} (acceptable), {@code .gif} (discouraged).</p>
+
+<p class="note"><strong>Note:</strong> Bitmap files may be automatically optimized with lossless
+image compression by the <a href="{@docRoot}guide/developing/tools/aapt.html">aapt</a> tool. For
+example, a true-color PNG that does not require more than 256 colors may be converted to an 8-bit
+PNG with a color palette. This will result in an image of equal quality but which requires less
+memory. So be aware that the image binaries placed in this directory can change during the build. If
+you plan on reading an image as a bit stream in order to convert it to a bitmap, put your images in
+the <code>res/raw/</code> folder instead, where they will not be optimized.</p>

+<h2 id="NinePatch">Nine-Patch File</h2>
+
+<p>A {@link android.graphics.NinePatch} is a PNG image in which you can define stretchable regions
+that Android will scale when content within the View exceeds the normal image bounds. You will
+typically assign this type of image as the background of a View that has at least one dimension set
+to {@code "wrap_content"}, and when the View grows to accomodate the content, the Nine-Patch image
+will also be scaled to match the size of the View. An example use of a Nine-Patch image is the
+background used by Android's standard {@link android.widget.Button} widget, which must stretch to
+accommodate the text (or image) inside the button.</p>
+
+<p>For a complete discussion about how to define a Nine-Patch file with stretchable regions,

+<h2 id="StateList">State List</h2>
+
+<p>A {@link android.graphics.drawable.StateListDrawable} is a drawable object defined in XML
+that uses a several different images to represent the same graphic, depending on the state of
+the object. For example, a {@link
+android.widget.Button} widget can exist in one of several different states (pressed, focused,
+or niether) and, using a state list drawable, you can provide a different button image for each
+state.</p>
+
+<p>You can describe the state list in an XML file. Each graphic is represented by an {@code
+<item>} element inside a single {@code <selector>} element. Each {@code <item>}
+uses various attributes to describe the state in which it should be used as the graphic for the
+drawable.</p>
+<p>During each state change, the state list is traversed top to bottom and the first item that
+matches the current state will be used—the selection is <em>not</em> based on the "best
+match," but simply the first item that meets the minimum criteria of the state.</p>

-<p>Resources are an integral part of an Android application.
-In general, these are external elements that you want to include and reference within your application,
-like images, audio, video, text strings, layouts, themes, etc. Every Android application contains
-a directory for resources (<code>res/</code>) and a directory for assets (<code>assets/</code>).
-Assets are used less often, because their applications are far fewer. You only need to save data
-as an asset when you need to read the raw bytes. The directories for resources and assets both
-reside at the top of an Android project tree, at the same level as your source code directory
-(<code>src/</code>).</p>
-<p>The difference between "resources" and "assets" isn't much on the surface, but in general,
-you'll use resources to store your external content much more often than you'll use assets.
-The real difference is that anything
-placed in the resources directory will be easily accessible from your application from the
-<code>R</code> class, which is compiled by Android. Whereas, anything placed in the assets
-directory will maintain its raw file format and, in order to read it, you must use the
-{@link android.content.res.AssetManager} to read the file as a stream of bytes. So keeping
-files and data in resources (<code>res/</code>) makes them easily accessible.</p>
+<p>You should always externalize resources such as images and strings from your application
+code, so that you can maintain them independently. Externalizing your
+resources also allows you to provide alternative resources that support specific device
+configurations such as different languages or screen sizes, which becomes increasingly
+important as more Android-powered devices become available with different configurations. In order
+to provide this functionality, you must organize resources in your project's {@code res/}
+directory, using various sub-directories that group resources by type and configuration.</p>
-<p>Within the documents of this topic, you'll find information on the kinds of standard resources
-that are typically used in an Android application and how to reference them from you code.
-<a href="{@docRoot}guide/topics/resources/resources-i18n.html">Resources and Internationalization</a>
-is where you should start, to learn more about how Android utilizes project resources. Then, the
-<a href="{@docRoot}guide/topics/resources/available-resources.html">Available Resource Types</a>
-document offers a summary of various resource types and a reference to their specifications.

+<strong>Figure 2.</strong> Two device configurations, one using alternative
+resources.</p>
+</div>
+
+<p>For any type of resource, you can specify <em>default</em> and multiple
+<em>alternative</em> resources for your application:</p>
+<ul>
+ <li>Default resources are those that should be used regardless of
+the device configuration or when there are no alternative resources that match the current
+configuration.</li>
+ <li>Alternative resources are those that you've designed for use with a specific
+configuration. To specify that a group of resources are for a specific configuration,
+append an appropriate configuration qualifier to the directory name.</li>
+</ul>
+
+<p>For example, while your default UI
+layout is saved in the {@code res/layout/} directory, you might specify a different UI layout to
+be used when the screen is in landscape orientation, by saving it in the {@code res/layout-land/}
+directory. The Android system will automatically apply the appropriate resources by matching the
+device's current configuration to your resource directory names.</p>
+
+<p>Figure 1 demonstrates how a collection of default resources from an application will be applied
+to two different devices when there are no alternative resources available. Figure 2 shows
+the same application with a set of alternative resources that qualify for one of the device
+configurations, thus, the two devices uses different resources.</p>
+
+<p>The information above is just an introduction to how application resources work on Android.
+The following documents provide a complete guide to how you can organize your application resources,
+specify alternative resources, access them in your application, and more:</p>

+<!--
+<h2>Raw Assets</h2>
+
+<p>An alternative to saving files in {@code res/} is to save files in the {@code
+assets/} directory. This should only be necessary if you need direct access to original files and
+directories by name. Files saved in the {@code assets/} directory will not be given a resource
+ID, so you can't reference them through the {@code R} class or from XML resources. Instead, you can
+query data in the {@code assets/} directory like an ordinary file system, search through the
+directory and
+read raw data using {@link android.content.res.AssetManager}. For example, this can be more useful
+when dealing with textures for a game. However, if you only need to read raw data from a file
+(such as a video or audio file), then you should save files into the {@code res/raw/} directory and
+then read a stream of bytes using {@link android.content.res.Resources#openRawResource(int)}. This
+is uncommon, but if you need direct access to original files in {@code assets/}, refer to the {@link
+android.content.res.AssetManager} documentation.</p>

+<h2 id="Dimension">Dimension</h2>
+
+<p>A dimension value defined in XML. A dimension
+is specified with a number followed by a unit of measure.
+For example: 10px, 2in, 5sp. The following units of measure are supported by Android:</p>
+<dl>
+ <dt>{@code dp}</dt>
+ <dd>Density-independent Pixels - an abstract unit that is based on the physical density of the screen.
+ These units are relative to a 160 dpi screen, so one dp is one pixel on a 160 dpi screen. The ratio of
+ dp-to-pixel will change with the screen density, but not necessarily in direct proportion. The
+ compiler accepts both "dip" and "dp", though "dp" is more consistent with "sp".</dd>
+ <dt>{@code sp}</dt>
+ <dd>Scale-independent Pixels - this is like the dp unit, but it is also scaled by the user's font
+ size preference. It is recommend you use this unit when specifying font sizes, so they will be adjusted
+ for both the screen density and the user's preference.</dd>
+ <dt>{@code pt}</dt>
+ <dd>Points - 1/72 of an inch based on the physical size of the screen.</dd>
+ <dt>{@code px}</dt>
+ <dd>Pixels - corresponds to actual pixels on the screen. This unit of measure is not recommended because
+ the actual representation can vary across devices; each devices may have a different number of pixels
+ per inch and may have more or fewer total pixels available on the screen.</dd>
+ <dt>{@code mm}</dt>
+ <dd>Millimeters - based on the physical size of the screen.</dd>
+ <dt>{@code in}</dt>
+ <dd>Inches - based on the physical size of the screen.</dd>

+<strong>Figure 1.</strong> Two device configurations, one using alternative resources.</p>
+</div>
+
+<p>Almost every application should provide alternative resources to support specific device
+configurations. For instance, you should include different drawable resources for different
+screen densities and different string resources for different languages. At runtime, Android
+will automatically detect the current device configuration and then load the appropriate
+resources.</p>
+
+<p>For each set of resources for which you want to provide configuration-specific alternatives:</p>
+<ol>
+ <li>Create a new directory in {@code res/} named in the form {@code
+<em><resources_name></em>-<em><config_qualifier></em>}.
+ <ul>
+ <li><em>{@code <resources_name>}</em> is the directory name of the corresponding default
+resources.</li>
+ <li><em>{@code <config_qualifier>}</em> is a name that specifies a configuration
+for which these resources are to be used.</li>
+ </ul>
+ <p>You can append more than one <em>{@code <config_qualifier>}</em>. Separate each
+one with a dash.</p>
+ </li>
+ <li>Save your alternative resources in this directory, named exactly the same as the default
+resource files.</li>
+</ol>
+
+<p>For example, here are some default and alternative resources:</p>
+
+<pre class="no-pretty-print">
+res/
+ drawable/ <span style="color:black">
+ icon.png
+ background.png </span>
+ drawable-hdpi/ <span style="color:black">
+ icon.png
+ background.png </span>
+</pre>
+
+<p>The {@code hdpi} qualifier indicates that the resources are for devices with a high-density
+screen. While the images in each directory are different, the filenames are
+identical. This way, the resource ID that you use to reference the {@code icon.png} image is
+always the same. When you request the {@code icon} drawable, Android will select the
+version of that drawable that best matches the current device configuration.</p>
+
+<p>Android supports several configuration qualifiers and you can
+add multiple qualifiers to one directory name in order to further specify the configuration, by
+separating the qualifiers with dashes. Table 2 lists the valid configuration qualifiers, in order
+of precedence—they must be specified in the directory name in the order that they are listed
+in the table.</p>
+
+
+<p class="table-caption" id="table2"><strong>Table 2.</strong> Alternative resource qualifier

+resources in your application, but if you only need to specify based on language, then use the
+language and region qualifier below. If you decide to use the MCC and MNC qualifier, you
+should do so with great care and completely test that it works as expected.</p></td>

+</table>
+
+<p>Here are some important rules about using resource qualifier names:</p>
+
+<ul>
+ <li>You can specify multiple qualifiers for a single set of resources, separated by dashes. For
+example, <code>drawable-en-rUS-land</code> applies to US-English devices in landscape
+orientation.</li>
+ <li>The qualifiers must be in the order listed in <a href="#table2">Table 2</a> above. For
+example:
+ <ul>
+ <li>Wrong: <code>drawable-hdpi-port/</code></li>
+ <li>Correct: <code>drawable-port-hdpi/</code></li>
+ </ul>
+ </li>
+ <li>Qualified directories cannot be nested. For example, you cannot have
+<code>res/drawable/drawable-en/</code>.</li>
+ <li>Values are case-insensitive. The resource compiler converts directory names
+ to lower case before processing to avoid problems on case-insensitive
+ file systems. Any capitalization in the names is only to benefit readability.</li>
+ <li>Only one value for each qualifier type is supported. For example, if you want to use
+the same drawable files for Spain and France, you <em>cannot</em> have a directory named
+<code>drawable-rES-rFR/</code>. Instead you need two resource directories, such as
+<code>drawable-rES/</code> and <code>drawable-rFR/</code>, which contain the appropriate files.
+However, you are not required to actually duplicate the same files in both locations (which
+could multiply the size of your package if the files are large). Instead, you can create a
+reference to one instance of the resources. See <a href="#AliasResources">Creating
+alias resources</a>, below.</li>
+</ul>
+
+
+
+<h3 id="AliasResources">Creating alias resources</h3>
+
+<p>When you have a resource that you'd like to use for more than one device
+configuration (but not for all configurations), you <em>don't</em> have to put the same resource in
+each of the alternative resource directories. Instead, you can (in some cases) create an alternative
+resource that acts as an alias for a resource saved in your default resource directory.</p>
+
+<p>For example, imagine you have an image, {@code icon.png}, and you have different versions of it
+for different locales, but two locales, English-Canadian and French-Canadian, need to
+use the same version. You might assume that you need to copy the Canadian version of the
+icon into the alternative resource directory for both English-Canadian and French-Canadian, but it's
+not true. What you can do instead is save the Canadian version as {@code icon_ca.png} (any name
+other than {@code icon.png}) and put
+it in the default {@code res/drawable/} directory. Then create an {@code icon.xml} file in {@code
+res/drawable-en-rCA/} and {@code res/drawable-fr-rCA/} that refers to the {@code icon_ca.png}
+resource using the {@code <bitmap>} element. This allows you to store just one version of the
+PNG file and two small XML files that point to it. (An example XML file is shown below.)</p>
+
+<p class="note"><strong>Note:</strong> Not all resources offer a mechanism by which you can
+create an alias to another resource. In particular, animation, menu, raw, and other unspecified
+resources in the {@code xml/} directory don't provide this kind of feature.</p>
+
+
+<h4>Drawable</h4>
+
+<p>To create an alias to an existing drawable, use the {@code <bitmap>} element.
+For example:</p>
+
+<pre>
+<?xml version="1.0" encoding="utf-8"?>
+<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
+ android:src="@drawable/icon_ca" />
+</pre>
+
+<p>If you save this file as {@code icon.xml}, it will be compiled into a resource that you
+can reference as {@code R.drawable.icon}, but is actually an alias for the {@code
+R.drawable.icon_ca} resource.</p>
+
+
+<h4>Layout</h4>
+
+<p>To create an alias to an existing layout, use the {@code <include>}
+element, wrapped in a {@code <merge>}. For example:</p>
+
+<pre>
+<?xml version="1.0" encoding="utf-8"?>
+<merge>
+ <include layout="@layout/main_ltr"/>
+</merge>
+</pre>
+
+<p>If you save this file as {@code main.xml}, it will be compiled into a resource you can reference
+as {@code R.layout.main}, but is actually an alias for the {@code R.layout.main_ltr}
+resource.</p>
+
+
+<h4>Strings and other simple values</h4>
+
+<p>To create an alias to an existing string, simply use the resource ID of the desired
+string as the value for the new string. For example:</p>
+
+<pre>
+<?xml version="1.0" encoding="utf-8"?>
+<resources>
+ <string name="hello">Hello</string>
+ <string name="hi">@string/hello</string>
+</resources>
+</pre>
+
+<p>The {@code R.string.hi} resource is now an alias for the {@code R.string.hello}.</p>
+
+<p> <a href="{@docRoot}guide/topics/resources/more-resources.html">Other simple values</a> work the
+same way. For example, a color:</p>
+
+<pre>
+<?xml version="1.0" encoding="utf-8"?>
+<resources>
+ <color name="yellow">#f00</color>
+ <color name="highlight">@color/red</color>
+</resources>
+</pre>
+
+
+
+
+
+
+<h2 id="BestMatch">How Android Finds the Best-matching Resource</h2>
+
+<p>Once you have saved alternative resources for your application, Android will pick which of the
+various underlying resource files should be used at runtime for each resource
+requested, depending on the current device configuration. To demonstrate how Android will select the
+resource to use, assume the following drawables are available:</p>
+
+<pre class="no-pretty-print">
+res/drawable/
+res/drawable-en/
+res/drawable-fr-rCA/
+res/drawable-en-port/
+res/drawable-en-notouch-12key/
+res/drawable-port-ldpi/
+res/drawable-port-notouch-12key
+</pre>
+
+<p>And assume the following is the device configuration:</p>
+
+<p style="margin-left:2em;">
+Locale = <code>en-GB</code> <br/>
+Screen orientation = <code>port</code> <br/>
+Screen pixel density = <code>hdpi</code> <br/>
+Touchscreen type = <code>notouch</code> <br/>
+Primary text input method = <code>12key</code>
+</p>
+
+
+<p>Here is how Android makes the drawable selection and how a drawable will be selected from the
+configuration above: </p>
+
+<ol>
+ <li>Eliminate resource files that contradict the device configuration.
+ <p>The <code>drawable-fr-rCA/</code> directory will be eliminated, because it
+contradicts the locale of the device.</p>
+<pre class="no-pretty-print">
+drawable/
+drawable-en/
+<strike>drawable-fr-rCA/</strike>
+drawable-en-port/
+drawable-en-notouch-12key/
+drawable-port-ldpi/
+drawable-port-notouch-12key
+</pre>
+<p class="note"><strong>Exception: </strong>Screen pixel density is the one qualifier that is not
+used to eliminate files. Even though the screen density of the device is mdpi,
+<code>drawable-port-ldpi/</code> is not eliminated because every screen density is
+considered to be a match at this point.</p></li>
+
+ <li>From <a href="#table2">Table 2</a>, pick the (next) highest-precedence qualifier in
+the list. (Start with MCC, then move down through the list.) </li>
+ <li>Do any of the available resource directories include this qualifier? </li>
+ <ul>
+ <li>If No, return to step 2 and look at the next qualifier. In the example,
+ the answer is "no" until the language qualifier is reached.</li>
+ <li>If Yes, move on to step 4.</li>
+ </ul>
+ </li>
+
+ <li>Eliminate resource directories that do not include this qualifier. In the example, the system
+eliminates all the directories that do not include a language qualifier:</li>
+<pre class="no-pretty-print">
+<strike>drawable/</strike>
+drawable-en/
+drawable-en-port/
+drawable-en-notouch-12key/
+<strike>drawable-port-ldpi/</strike>
+<strike>drawable-port-notouch-12key</strike>
+</pre>
+<p class="note"><strong>Exception:</strong> If the qualifier in question is screen pixel density,
+Android will
+select the option that most closely matches the device, and the selection process will be complete.
+In general, Android will prefer scaling down a larger original image to scaling up a smaller
+original image.</p>
+ </li>
+
+ <li>Go back and repeat steps 2, 3, and 4 until only one choice remains. In the example, screen
+orientation is the next qualifier for which there are any matches.
+So, resources that do not specify a screen orientation are eliminated:
+<pre class="no-pretty-print">
+<strike>drawable-en/</strike>
+drawable-en-port/
+<strike>drawable-en-notouch-12key/</strike>
+</pre>
+<p>Only one choice remains, so the drawable will be taken from the {@code drawable-en-port}
+directory.</p>
+ </li>
+</ol>
+
+<p>Though this procedure is executed for each resource requested, the system will further optimize
+some aspects. One such optimization is that once the device configuration is known, it might
+completely eliminate alternative resources that can never match. For example, if the configuration
+language is English ("en"), then any resource directory that has a language qualifier set to
+something other than English will never be included in the pool of resources checked (though a
+resource directory <em>without</em> the language qualifier is still included).</p>
+
+<p class="note"><strong>Note:</strong> The <em>precedence</em> of the qualifier (in <a
+href="#table2">Table 2</a>) is more important
+than the number of qualifiers that exactly match the device. For example, in step 4 above, the last
+choice on the list includes three qualifiers that exactly match the device (orientation, touchscreen
+type, and input method), while <code>drawable-en</code> has only one parameter that matches
+(language). However, language has a higher precedence than these other qualifiers, so
+<code>drawable-port-notouch-12key</code>
+is out.</p>
+
+<p>The following flowchart summarizes how Android selects the resource directory to use.</p>

-<p>Resources are external files (that is, non-code files) that are used by
-your code and compiled into your application at build time. Android
-supports a number of different kinds of resource files, including XML,
-PNG, and JPEG files. The XML files have very different formats depending
-on what they describe. This document describes what kinds of files are
-supported, and the syntax or format of each.</p>
-<p>Resources are externalized from source code, and XML files are compiled into
-a binary, fast loading format for efficiency reasons. Strings, likewise, are compressed
-into a more efficient storage form. It is for these reasons that we have these
-different resource types in the Android platform.</p>
-
-<p>This is a fairly technically dense document, and together with the
-<a href="available-resources.html">Available Resources</a>
-document, they cover a lot of information about resources. It is not necessary
-to know this document by heart to use Android, but rather to know that the
-information is here when you need it.</p>
-
-<a name="intro"></a>
-<h2>Introduction</h2>
-
-<p>This topic includes a terminology list associated with resources, and a series
- of examples of using resources in code. For a complete guide to the supported
- Android resource types, see
- <a href="available-resources.html">Available Resources</a>.
- </p>
-<p>The Android resource system keeps track of all non-code
- assets associated with an application. You use the
- {@link android.content.res.Resources Resources} class to access your
- application's resources; the Resources instance associated with your
- application can generally be found through
- {@link android.content.Context#getResources Context.getResources()}.</p>
-<p>An application's resources are compiled into the application
-binary at build time for you by the build system. To use a resource,
-you must install it correctly in the source tree and build your
-application. As part of the build process, symbols for each
-of the resources are generated that you can use in your source
-code -- this allows the compiler to verify that your application code matches
-up with the resources you defined.</p>
-
-<p>The rest of this section is organized as a tutorial on how to
-use resources in an application.</p>
-
-<a name="CreatingResources" id="CreatingResources"></a>
-<h2>Creating Resources</h2>
-
-<p>Android supports string, bitmap, and many other types of resource. The syntax and format
-of each, and where they're stored, depends upon the type of object. In
-general, though, you create resources from three types of files: XML files
-(everything but bitmaps and raw), bitmap files(for images) and Raw files (anything
-else, for example sound files, etc.). In fact, there are two different types of
-XML file as well, those that get compiled as-is into the package, and those that
-are used to generate resources by aapt. Here is a list of each
-resource type, the format of the file, a description of the file, and details
-of any XML files. </p>
-
-<p>You will create and store your resource files under the appropriate
-subdirectory under the <code>res/</code> directory in your project. Android
-has a resource compiler (aapt) that compiles resources according to which
-subfolder they are in, and the format of the file. Table 1 shows a list of the file
-types for each resource. See the
-<a href="available-resources.html">Available Resources</a> for
-descriptions of each type of object, the syntax, and the format or syntax of
-the containing file.</p>

- <li><a href="available-resources.html#ninepatch">9-patches (resizable bitmaps)</a></li>
- </ul>
- <p>To get a resource of this type, use <code>mContext.getResources().getDrawable(R.drawable.<em>imageId</em>)</code></p>
- <p class="note"><strong>Note:</strong> Image resources placed in here may
- be automatically optimized with lossless image compression by the
- <a href="{@docRoot}guide/developing/tools/aapt.html">aapt</a> tool. For example, a true-color PNG
- that does not require more than 256 colors may be converted to an 8-bit PNG with a color palette.
- This will result in an image of equal quality but which requires less memory. So be aware that the
- image binaries placed in this directory can change during the build. If you plan on reading
- an image as a bit stream in order to convert it to a bitmap, put your images in the
- <code>res/raw/</code> folder instead, where they will not be optimized.</p>

-<h3>Global Resource Notes</h3>
-<ul>
- <li>Several resources allow you to define colors. Android accepts color values
- written in various web-style formats -- a hexadecimal constant in any of the
- following forms: #RGB, #ARGB, #RRGGBB, #AARRGGBB. </li>
- <li>All color values support setting an alpha channel value, where the first
- two hexadecimal numbers specify the transparency. Zero in the alpha channel
- means transparent. The default value is opaque. </li>
-</ul>
-<a name="UsingResources" id="UsingResources"></a>
-<h2>Using Resources </h2>
-<p>This section describes how to use the resources you've created. It includes the
- following topics:</p>
-<ul>
- <li><a href="#ResourcesInCode">Using resources in code</a> - How to call
- resources in your code to instantiate them. </li>
- <li><a href="#ReferencesToResources">Referring to resources from other resources</a> -
- You can reference resources from other resources. This lets you reuse common
- resource values inside resources. </li>
- <li><a href="#AlternateResources">Supporting Alternate Resources for Alternate
- Configurations</a> - You can specify different resources
- to load, depending on the language or display configuration of the host
- hardware. </li>
-</ul>
-<p>At compile time, Android generates a class named R that contains resource identifiers
- to all the resources in your program. This class contains several subclasses,
- one for each type of resource supported by Android, and for which you provided
- a resource file. Each class contains one or more identifiers for the compiled resources,
- that you use in your code to load the resource. Here is a small resource file
- that contains string, layout (screens or parts of screens), and image resources.</p>
-<p class="note"><strong>Note:</strong> the R class is an auto-generated file and is not
-designed to be edited by hand. It will be automatically re-created as needed when
-the resources are updated.</p>

-<h3>Using Resources in Code </h3>
-
-<p>Using resources in code is just a matter of knowing the full resource ID
-and what type of object your resource has been compiled into. Here is the
-syntax for referring to a resource:</p>
-<p><code>R.<em>resource_type</em>.<em>resource_name</em></code></p>
-<p>or</p>
-<p><code>android.R.<em>resource_type</em>.<em>resource_name</em></code></p>
-
-<p>Where <code>resource_type</code> is the R subclass that holds a specific type
-of resource. <code>resource_name</code> is the <em>name</em> attribute for resources
-defined in XML files, or the file name (without the extension) for resources
-defined by other file types. Each type of resource will be added to a specific
-R subclass, depending on the type of resource it is; to learn which R subclass
-hosts your compiled resource type, consult the
-<a href="available-resources.html">Available Resources</a> document. Resources compiled by your own application can
-be referred to without a package name (simply as
-<code>R.<em>resource_type</em>.<em>resource_name</em></code>). Android contains
-a number of standard resources, such as screen styles and button backgrounds. To
-refer to these in code, you must qualify them with <code>android</code>, as in
-<code>android.R.drawable.button_background</code>.</p>
-
-<p>Here are some good and bad examples of using compiled resources in code:</p>
-
-<pre class="prettyprint">// Load a background for the current screen from a drawable resource.
-this.getWindow().setBackgroundDrawableResource(R.drawable.my_background_image);
-
-// WRONG Sending a string resource reference into a
-// method that expects a string.
-this.getWindow().setTitle(R.string.main_title);
-
-// RIGHT Need to get the title from the Resources wrapper.
-this.getWindow().setTitle(Resources.getText(R.string.main_title));
-
-// Load a custom layout for the current screen.
-setContentView(R.layout.main_screen);
-
-// Set a slide in animation for a ViewFlipper object.
-mFlipper.setInAnimation(AnimationUtils.loadAnimation(this,
- R.anim.hyperspace_in));
-
-// Set the text on a TextView object.
-TextView msgTextView = (TextView)findViewByID(R.id.msg);
-msgTextView.setText(R.string.hello_message); </pre>
-
-<a name="ReferencesToResources" id="ReferencesToResources"></a>
-<h3>References to Resources</h3>
-
-<p>A value supplied in an attribute (or resource) can also be a reference to
-a resource. This is often used in layout files to supply strings (so they
-can be localized) and images (which exist in another file), though a reference
-can be any resource type including colors and integers.</p>
-
-<p>For example, if we have
-<a href="available-resources.html#colordrawableresources">color
-resources</a>, we can write a layout file that sets the text color size to be
-the value contained in one of those resources:</p>
-
-<pre>
-<?xml version="1.0" encoding="utf-8"?>
-<EditText id="text"
- xmlns:android="http://schemas.android.com/apk/res/android"
- android:layout_width="fill_parent" android:layout_height="fill_parent"
- <strong>android:textColor="@color/opaque_red"</strong>
- android:text="Hello, World!" />
-</pre>
-
-<p>Note here the use of the '@' prefix to introduce a resource reference -- the
-text following that is the name of a resource in the form
-of <code>@[package:]type/name</code>. In this case we didn't need to specify
-the package because we are referencing a resource in our own package. To
-reference a system resource, you would need to write:</p>
-
-<pre>
-<?xml version="1.0" encoding="utf-8"?>
-<EditText id="text"
- xmlns:android="http://schemas.android.com/apk/res/android"
- android:layout_width="fill_parent" android:layout_height="fill_parent"
- android:textColor="@<strong>android:</strong>color/opaque_red"
- android:text="Hello, World!" />
-</pre>
-
-<p>As another example, you should always use resource references when supplying
-strings in a layout file so that they can be localized:</p>
-
-<pre>
-<?xml version="1.0" encoding="utf-8"?>
-<EditText id="text"
- xmlns:android="http://schemas.android.com/apk/res/android"
- android:layout_width="fill_parent" android:layout_height="fill_parent"
- android:textColor="@android:color/opaque_red"
- android:text="@string/hello_world" />
-</pre>
-
-<p>This facility can also be used to create references between resources.
-For example, we can create new drawable resources that are aliases for
-existing images:</p>
-
-<pre>
-<?xml version="1.0" encoding="utf-8"?>
-<resources>
- <drawable id="my_background">@android:drawable/theme2_background</drawable>
-</resources>
-</pre>
-
-<a name="ReferencesToThemeAttributes"></a>
-<h3>References to Theme Attributes</h3>
-
-<p>Another kind of resource value allows you to reference the value of an
-attribute in the current theme. This attribute reference can <em>only</em>
-be used in style resources and XML attributes; it allows you to customize the
-look of UI elements by changing them to standard variations supplied by the
-current theme, instead of supplying more concrete values.</p>
-
-<p>As an example, we can use this in our layout to set the text color to
-one of the standard colors defined in the base system theme:</p>
-
-<pre>
-<?xml version="1.0" encoding="utf-8"?>
-<EditText id="text"
- xmlns:android="http://schemas.android.com/apk/res/android"
- android:layout_width="fill_parent" android:layout_height="fill_parent"
- <strong>android:textColor="?android:textDisabledColor"</strong>
- android:text="@string/hello_world" />
-</pre>
-
-<p>Note that this is very similar to a resource reference, except we are using
-an '?' prefix instead of '@'. When you use this markup, you are supplying
-the name of an attribute resource that will be looked up in the theme --
-because the resource tool knows that an attribute resource is expected,
-you do not need to explicitly state the type (which would be
-<code>?android:attr/android:textDisabledColor</code>).</p>
-
-<p>Other than using this resource identifier to find the value in the
-theme instead of raw resources, the name syntax is identical to the '@' format:
-<code>?[namespace:]type/name</code> with the type here being optional.</p>
-
-<a name="UsingSystemResources"></a>
-<h3>Using System Resources</h3>
-
-<p>Many resources included with the system are available to applications.
-All such resources are defined under the class "android.R". For example,
-you can display the standard application icon in a screen with the following
-code:</p>
-
-<pre class="prettyprint">
-public class MyActivity extends Activity
-{
- public void onStart()
- {
- requestScreenFeatures(FEATURE_BADGE_IMAGE);
-
- super.onStart();
-
- setBadgeResource(android.R.drawable.sym_def_app_icon);
- }
-}
-</pre>
-
-<p>In a similar way, this code will apply to your screen the standard
-"green background" visual treatment defined by the system:</p>
-
-<pre class="prettyprint">
-public class MyActivity extends Activity
-{
- public void onStart()
- {
- super.onStart();
-
- setTheme(android.R.style.Theme_Black);
- }
-}
-</pre>
-
-<a name="AlternateResources" id="AlternateResources"></a>
-<h2>Alternate Resources (for alternate languages and configurations)</h2>
-
-<p>You can supply different resources for your application to use depending on the UI
-language or hardware configuration on the device. Note that although you can
-include different string, layout, and other resources, the SDK does not expose
-methods to let you specify which alternate resource set to load. Android
-detects the proper set for the hardware and location, and loads them as
-appropriate. Users can select alternate language settings using the settings
-panel on the device. </p>
-<p>To include alternate resources, create parallel resource folders with
-qualifiers appended to the folder names, indicating the configuration it
-applies to (language, screen orientation, and so on). For example, here is a
-project that holds one string resource file for English, and another for
-French:</p>
-
-<pre>
-MyApp/
- res/
- values-en/
- strings.xml
- values-fr/
- strings.xml
-</pre>
-
-<p>Android supports several types of qualifiers, with various values for each.
-Append these to the end of the resource folder name, separated by dashes. You
-can add multiple qualifiers to each folder name, but they must appear in the
-order they are listed here. For example, a folder containing drawable
-resources for a fully specified configuration would look like this:</p>
-
-<pre>
-MyApp/
- res/
- drawable-en-rUS-large-long-port-mdpi-finger-keysexposed-qwerty-navexposed-dpad-480x320/
-</pre>
-
-<p>More typically, you will only specify a few specific configuration options. You may drop any of the values from the
-complete list, as long as the remaining values are still in the same
-order:</p>
-
-<pre>
-MyApp/
- res/
- drawable-en-rUS-finger/
- drawable-port/
- drawable-port-mdpi/
- drawable-qwerty/
-</pre>
-<p>Table 2 lists the valid folder-name qualifiers, in order of precedence. Qualifiers that are listed higher in the table take precedence over those listed lower, as described in <a href="#best-match">How Android finds the best matching directory</a>. </p>
-<p class="caption" id="table2">Table 2</p>
-<table border="1">

- <code>mcc208-mnc00</code> (France, Orange brand);
- <code>mcc234-mnc00</code> (U.K., BT brand).
- </p><p>
- If the device uses a radio connection (GSM phone), the MCC will come
- from the SIM, and the MNC will come from the network to which the
- device is attached. You might sometimes use the MCC alone, for example
- to include country-specific legal resources in your application. If

- medium density screen. A screen is considered to be normal if it is
- at least this size (independent of density) and not large. Examples
- of such screens a WQVGA low density, HVGA medium density, WVGA
- high density.
- <li> <b>Small screens</b> are based on the space available on a
- QVGA low density screen. Considering a portrait HVGA display, this has
- the same available width but less height -- it is 3:4 vs. HVGA's
- 2:3 aspect ratio. Examples are QVGA low density and VGA high
- density.
- <li> <b>Large screens</b> are based on the space available on a
- VGA medium density screen. Such a screen has significantly more
- available space in both width and height than an HVGA display.
- Examples are VGA and WVGA medium density screens.
- </td>
- </tr>
- <tr>
- <td>Wider/taller screens</td>
- <td><p><code>long</code>, <code>notlong</code>

- Specify that the resource is for a taller/wider than traditional

- QVGA, HVGA, and VGA are notlong; WQVGA, WVGA, FWVGA are long. Note
- that long may mean either wide or tall, depending on the current
- orientation.</p>
- </td>
- </tr>
- <tr>
- <td>Screen orientation</td>
- <td><p><code>port</code>, <code>land</code>, <code>square</code>
- </p><p>
- Specifies that the resource is for a screen that is tall (port)
- or wide (land); square is not currently used.</p>
- </td>
- </tr>
- <tr>
- <td>Screen pixel density</td>
- <td><p><code>ldpi</code>, <code>mdpi</code>, <code>hdpi</code>, <code>nodpi</code>
- </p><p>
- Specifies the screen density the resource is defined for. The medium
- density of traditional HVGA screens (mdpi) is defined to be approximately
- 160dpi; low density (ldpi) is 120, and high density (hdpi) is 240. There
- is thus a 4:3 scaling factor between each density, so a 9x9 bitmap
- in ldpi would be 12x12 is mdpi and 16x16 in hdpi. The special
- <code>nodpi</code> density can be used with bitmap resources to prevent
- them from being scaled at load time to match the device density.
- </p><p>
- When Android selects which resource files to use,
- it handles screen density differently than the other qualifiers.
- In step 1 of <a href="#best-match">How Android finds the best
- matching directory</a> (below), screen density is always considered to
- be a match. In step 4, if the qualifier being considered is screen
- density, Android will select the best final match at that point,
- without any need to move on to step 5.
- </p><p>
- You can also specify explicit densities like <code>92dpi</code>
- or <code>108dpi</code>, but these are not fully supported by the
- system so should not be used.

-
-<p>This list does not include device-specific parameters such as carrier,
-branding, device/hardware, or manufacturer. Everything that an application
-needs to know about the device that it is running on is encoded via the
-resource qualifiers in the table above.</p>
-
-<p>All resource directories, qualified and unqualified, live under the <code>res/</code> folder. Here are some guidelines on qualified resource directory names:</p>
-
-<ul>
- <li>You can specify multiple qualifiers, separated by dashes. For example, <code>drawable-en-rUS-land</code> will apply to US-English
- devices in landscape orientation. </li>
- <li>The qualifiers must be in the order listed in <a href="#table2">Table 2</a> above. For example:
- <ul>
- <li>Correct: <code>values-mcc460-nokeys/</code></li>
- <li>Incorrect: <code>values-nokeys-mcc460/</code></li>
- </ul>
- </li>
- <li>Values are case-insensitive. The resource compiler converts folder names
- to lower case before processing to avoid problems in case-insensitive
- file systems. On case-sensitive file systems, you should keep all names
- lower-case or at least use a consistent case to protect your future
- sanity when trying to find a resource file.</li>
- <li>Only one value for each qualifier type is supported. For example, if you want to use exactly the same drawable files for Spain and France, you will need two resource directories, such as <code>drawable-rES/</code> and <code>drawable-rFR/</code>, containing identical files. You cannot
- have a directory named <code>drawable-rES-rFR/</code>. </li>
- <li>Qualified directories cannot be nested. For example, you cannot have <code>res/drawable/drawable-en</code>. </li>
-</ul>
-
-<h3>How resources are referenced in code</h3>
-<p>All resources will be referenced in code or resource reference syntax by
- their simple, undecorated names. So if a resource were named this:<br />
- <code>MyApp/res/drawable-port-mdpi/myimage.png</code><br />
- It would be referenced as this:<br />
- <code>R.drawable.myimage</code> (code)<br />
- <code>@drawable/myimage</code> (XML)</p>
-<p>If several drawable directories are available, Android will select one of them (as described below) and load <code>myimage.png</code> from it.</p>
-<h3 id="best-match">How Android finds the best matching directory </h3>
-
-<p>Android will pick which of the various underlying resource files should be
-used at runtime, depending on the current configuration of the device.
-The example used here assumes the following device configuration:</p>
-
- <p style="margin-left:2em">Locale = <code>en-GB</code><br>
- Screen orientation = <code>port</code><br>
- Screen pixel density = <code>mdpi</code><br>
- Touchscreen type = <code>notouch</code><br>
- Primary text input method = <code>12key</code><br>
- </p>
-
-<p>Here is how Android makes the selection: </p>
-<ol>
- <li>
- Eliminate resource files that contradict the
- device configuration. For example, assume that the following resource directories are available for drawables. The <code>drawable-fr-rCA/</code> directory will be eliminated, because it contradicts the locale of the device.<br>
-<pre>MyApp/res/drawable/
-MyApp/res/drawable-en/
-<strike>MyApp/res/drawable-fr-rCA/</strike>
-MyApp/res/drawable-en-port/
-MyApp/res/drawable-en-notouch-12key/
-MyApp/res/drawable-port-ldpi/
-MyApp/res/drawable-port-notouch-12key</pre>
- <strong>Exception: </strong>Screen pixel density is the one qualifier that is not used to eliminate files. Even though the screen density of the device is medium dpi, <code>drawable-port-ldpi/</code> is not eliminated from the list, because every screen density is considered to be a
- match at this point.</li>
- <li>From <a href="#table2">Table 2</a>, pick the highest-precedence qualifier that remains in the list. (Start with MCC, then move down through the list.) </li>
- <li>Do any of the available resource directories include this qualifier? </li>
- <ul>
- <li>If No, return to step 2 and look at the next qualifier listed in Table 2. In our example, the answer is "no" until we reach Language.</li>
- <li>If Yes, move on to step 4.</li>
- </ul>
- <li>Eliminate resource directories that do not include this qualifier. In our example, we eliminate all the directories that do not include a language qualifier. </li>
- <pre><strike>MyApp/res/drawable/</strike>
-MyApp/res/drawable-en/
-MyApp/res/drawable-en-port/
-MyApp/res/drawable-en-notouch-12key/
-<strike>MyApp/res/drawable-port-ldpi/</strike>
-<strike>MyApp/res/drawable-port-notouch-12key</strike></pre>
- <strong>Exception:</strong> If the qualifier in question is screen pixel density, Android will select the option that most closely matches the device, and the selection process will be complete. In general, Android will prefer scaling down a larger original image to scaling up a smaller original image.<br><br></li>
-
-<li>Go back and repeat steps 2, 3, and 4 until only one choice remains. In the example, screen orientation is the next qualifier in the table for which we have any matches.
- Eliminate resources that do not specify a screen orientation. </p>
- <pre><strike>MyApp/res/drawable-en/</strike>
-MyApp/res/drawable-en-port/
-<strike>MyApp/res/drawable-en-notouch-12key/</strike></pre>
- Only one choice remains, so that's it. When drawables are called for in this
- example application, the Android system will load resources from the
- <code>MyApp/res/drawable-en-port/</code> directory. In addition, if the
- resource being loaded is a bitmap, it will be scaled up so that its supplied
- low density matches the device's medium density.
-</ol>
-<p class="note"><strong>Tip:</strong> The <em>precedence</em> of the qualifiers is more important than the number of qualifiers that exactly match the device. For example, in step 4 above, the last choice on the list includes three qualifiers that exactly match the device (orientation, touchscreen type, and input method), while <code>drawable-en</code> has only one parameter that matches (language). However, language has a higher precedence, so <code>drawable-port-notouch-12key</code> is out.</p>

-<h3>Terminology</h3>
-<p>The resource system brings a number of different pieces together to
-form the final complete resource functionality. To help understand the
-overall system, here are some brief definitions of the core concepts and
-components you will encounter in using it:</p>
-
-<p><strong>Asset</strong>: A single blob of data associated with an application. This
-includes object files compiled from the Java source code, graphics (such as PNG
-images), XML files, etc. These files are organized in a directory hierarchy
-that, during final packaging of the application, is bundled together into a
-single ZIP file.</p>
-
-<p><strong>aapt</strong>: Android Asset Packaging Tool. The tool that generates the
-final ZIP file of application assets. In addition to collecting raw assets
-together, it also parses resource definitions into binary asset data.</p>
-
-<p><strong>Resource Table</strong>: A special asset that aapt generates for you,
-describing all of the resources contained in an application/package.
-This file is accessed for you by the Resources class; it is not touched
-directly by applications.</p>
-
-<p><strong>Resource</strong>: An entry in the Resource Table describing a single
-named value. Broadly, there are two types of resources: primitives and
-bags.</p>
-
-<p><strong>Resource Identifier</strong>: In the Resource Table all resources are
-identified by a unique integer number. In source code (resource descriptions,
-XML files, Java source code) you can use symbolic names that stand as constants for
-the actual resource identifier integer.</p>
-
-<p><strong>Primitive Resource</strong>: All primitive resources can be written as a
-simple string, using formatting to describe a variety of primitive types
-included in the resource system: integers, colors, strings, references to
-other resources, etc. Complex resources, such as bitmaps and XML
-describes, are stored as a primitive string resource whose value is the path
-of the underlying Asset holding its actual data.</p>
-
-<p><strong>Bag Resource</strong>: A special kind of resource entry that, instead of a
-simple string, holds an arbitrary list of name/value pairs. Each name is
-itself a resource identifier, and each value can hold
-the same kinds of string formatted data as a normal resource. Bags also
-support inheritance: a bag can inherit the values from another bag, selectively
-replacing or extending them to generate its own contents.</p>
-
-<p><strong>Kind</strong>: The resource kind is a way to organize resource identifiers
-for various purposes. For example, drawable resources are used to
-instantiate Drawable objects, so their data is a primitive resource containing
-either a color constant or string path to a bitmap or XML asset. Other
-common resource kinds are string (localized string primitives), color
-(color primitives), layout (a string path to an XML asset describing a view
-layout), and style (a bag resource describing user interface attributes).
-There is also a standard "attr" resource kind, which defines the resource
-identifiers to be used for naming bag items and XML attributes</p>
-
-<p><strong>Style</strong>: The name of the resource kind containing bags that are used
-to supply a set of user interface attributes. For example, a TextView class may
-be given a style resource that defines its text size, color, and alignment.
-In a layout XML file, you associate a style with a bag using the "style"
-attribute, whose value is the name of the style resource.</p>
-
-<p><strong>Style Class</strong>: Specifies a related set of attribute resources.
-This data is not placed in the resource table itself, but used to generate
-constants in the source code that make it easier for you to retrieve values out of
-a style resource and/or XML tag's attributes. For example, the
-Android platform defines a "View" style class that
-contains all of the standard view attributes: padding, visibility,
-background, etc.; when View is inflated it uses this style class to
-retrieve those values from the XML file (at which point style and theme
-information is applied as appropriate) and load them into its instance.</p>
-
-<p><strong>Configuration</strong>: For any particular resource identifier, there may be
-multiple different available values depending on the current configuration.
-The configuration includes the locale (language and country), screen
-orientation, etc. The current configuration is used to
-select which resource values are in effect when the resource table is
-loaded.</p>
-
-<p><strong>Theme</strong>: A standard style resource that supplies global
-attribute values for a particular context. For example, when writing an
-Activity the application developer can select a standard theme to use, such
-as the Theme.White or Theme.Black styles; this style supplies information
-such as the screen background image/color, default text color, button style,
-text editor style, text size, etc. When inflating a layout resource, most
-values for widgets (the text color, selector, background) if not explicitly
-set will come from the current theme; style and attribute
-values supplied in the layout can also assign their value from explicitly
-named values in the theme attributes if desired.</p>
-
-<p><strong>Overlay</strong>: A resource table that does not define a new set of resources,
-but instead replaces the values of resources that are in another resource table.
-Like a configuration, this is applied at load time
-to the resource data; it can add new configuration values (for example
-strings in a new locale), replace existing values (for example change
-the standard white background image to a "Hello Kitty" background image),
-and modify resource bags (for example change the font size of the Theme.White
-style to have an 18 pt font size). This is the facility that allows the
-user to select between different global appearances of their device, or
-download files with new appearances.</p>

+
+<p>Some device configurations can change during runtime
+(such as screen orientation, keyboard availability, and language). When such a change occurs,
+Android's default behavior is to restart the running
+Activity ({@link android.app.Activity#onDestroy()} is called, followed by {@link
+android.app.Activity#onCreate(Bundle) onCreate()}). In doing so, the system re-queries your
+application resources for alternatives that might apply to the new configuration.</p>
+
+<p>It is important that your Activity safely handles restarts and restores its previous
+state through the normal <a href="{@docRoot}guide/topics/fundamentals.html#lcycles">Activity
+lifecycle</a>. In fact, it's a useful field test to invoke configuration changes (such as changing
+the screen orientation) during various states of your application to be sure that it properly
+restarts itself with the application state intact. So it's in the best interest of your application
+to allow the system to restart your application during any configuration change—this behavior
+is in place to help you by automatically handling configuration changes and adapting your
+application as necessary.</p>
+
+<p>However, you might encounter a situation in which restarting your application and
+restoring significant amounts of data can be costly, create a slow user experience, and
+using {@link android.app.Activity#onSaveInstanceState(Bundle) onSaveInstanceState()} does not
+suffice. In such a situation, you have two options:</p>
+
+<ol type="a">
+ <li><a href="#CarryingAnObject">Carrying an Object During a Configuration Change</a>
+ <p>Allow your
+application to restart so that the appropriate configuration changes can take effect, but also
+implement {@link android.app.Activity#onRetainNonConfigurationInstance()} paired with {@link
+android.app.Activity#getLastNonConfigurationInstance()} to carry an {@link java.lang.Object} over
+to the new instance of your Activity.</p>
+ <p>This is the recommended technique if you're facing performance issues during the
+configuration restart. It allows your Activity to properly restart and reload resources for
+the new configuration and also allows you to carry your arbitrary data that may be expensive to
+collect again.</p>
+ </li>
+ <li><a href="#HandlingTheChange">Handling the Configuration Change Yourself</a>
+ <p>Declare that your
+application will handle certain configuration changes and prevent the system from restarting your
+application when such a change occurs. For example, you can declare in your manifest that your
+Activity will handle configuration changes to the screen orientation. When the orientation
+changes, your Activity will not be restarted and your Activity will receive a call to {@link
+android.app.Activity#onConfigurationChanged(Configuration) onConfigurationChanged()} so that you can
+perform necessary changes based on the new configuration.</p>
+ <p>This technique should be considered a last resort and temporary solution, because not all
+runtime configuration changes can be handled this way—your application will eventually
+encounter a runtime configuration in which you cannot prevent the Activity from being restarted,
+whereas the first option will handle all configuration changes.</p>
+ </li>
+</ol>
+
+<p class="note"><strong>Note:</strong> Your application should always be able to successfully
+restart at any time without any loss of user data or state in order to handle other events such as
+when the user receives an incoming phone call and then returns to your application (read about the
+<a href="{@docRoot}guide/topics/fundamentals.html#lcycles">Activity lifecycle</a>). The following
+techniques for handling runtime configuration changes should only be necessary to optimize
+performance during specific configuration changes.</p>
+
+
+<h2 id="CarryingAnObject">Carrying an Object During a Configuration Change</h2>
+
+<p>If your application has acquired significant amounts of data during its life, which would be
+costly to recover due to a restart of the Activity, you can use {@link
+android.app.Activity#onRetainNonConfigurationInstance()} paired with {@link
+android.app.Activity#getLastNonConfigurationInstance()} to pass an {@link java.lang.Object}
+to the new Activity instance. The {@link android.app.Activity#onRetainNonConfigurationInstance()}
+method is called between {@link android.app.Activity#onStop()} and {@link
+android.app.Activity#onDestroy()} when your Activity is being shut down due to a configuration
+change. In your implementation of this method, you can return any {@link java.lang.Object} that you
+need to efficiently restore your state after the configuration change. When your Activity is
+created again, you can call {@link
+android.app.Activity#getLastNonConfigurationInstance()} to retrieve the {@link
+java.lang.Object}.</p>
+
+<p>A scenario in which this can be valuable is if your application loads a lot of data from the
+web. If the user changes the orientation of the device and the Activity restarts, your application
+will need to re-fetch the data, which could be slow. What you can do is implement
+{@link android.app.Activity#onRetainNonConfigurationInstance()} to return an object carrying your
+data and then retrieve the data when your Activity restarts with {@link
+android.app.Activity#getLastNonConfigurationInstance()}. For example:</p>
+
+<pre>
+@Override
+public Object onRetainNonConfigurationInstance() {
+ final MyDataObject data = collectMyLoadedData();
+ return data;
+}
+</pre>
+
+<p class="caution"><strong>Caution:</strong> While you can return any object, you
+should never pass an object that is tied to the {@link android.app.Activity}, such as a {@link
+android.graphics.drawable.Drawable}, an {@link android.widget.Adapter}, a {@link android.view.View}
+or any other object that's associated with a {@link android.content.Context}. If you do, it will
+leak all the Views and resources of the original Activity instance. (To leak the resources
+means that your application maintains a hold on them and they cannot be garbage-collected, so
+lots of memory can be lost.)</p>
+
+<p>Then get the {@code data} after the restart:</p>
+
+<pre>
+@Override
+public void onCreate(Bundle savedInstanceState) {
+ super.onCreate(savedInstanceState);
+ setContentView(R.layout.main);
+
+ final MyDataObject data = (MyDataObject) getLastNonConfigurationInstance();
+ if (data == null) {
+ data = loadMyData();
+ }
+ ...
+}
+</pre>
+
+<p>In this case, {@link android.app.Activity#getLastNonConfigurationInstance()} is called to get
+the data saved during the configuration change, and if it is null (which will happen if the
+Activity is started in any case other than a configuration change) then the data is loaded
+from the original source.</p>
+
+
+
+
+
+<h2 id="HandlingTheChange">Handling the Configuration Change Yourself</h2>
+
+<p>If your application doesn't need to update resources during a specific configuration
+change <em>and</em> you have a performance limitation that requires you to
+avoid the Activity restart, then you can declare that your Activity handles the configuration change
+itself, which will prevent the system from restarting your Activity.</p>
+
+<p class="note"><strong>Note:</strong> Handling the configuration change yourself can make it much
+more difficult to use alternative resources, because the system will not automatically apply them
+for you.</p>
+
+<p>To declare that your Activity handles a configuration change, edit the appropriate <a
+href="{@docRoot}guide/topics/manifest/activity-element.html">{@code <activity>}</a> element
+in your manifest file to include the <a
+href="{@docRoot}guide/topics/manifest/activity-element.html#config">{@code
+android:configChanges}</a> attribute with a string value that represents the configuration that you
+want to handle. Possible values are listed in the documentation for
+the <a href="{@docRoot}guide/topics/manifest/activity-element.html#config">{@code
+android:configChanges}</a> attribute (the most commonly used values are {@code orientation} to
+handle when the screen orientation changes and {@code keyboardHidden} to handle when the
+keyboard availability changes). You can declare multiple configuration values in the attribute
+by separating them with a pipe character ("|").</p>
+
+<p>For example, the following manifest snippet declares an Activity that handles both the
+screen orientation change and keyboard availability change:</p>
+
+<pre>
+<activity android:name=".MyActivity"
+ android:configChanges="orientation|keyboardHidden"
+ android:label="@string/app_name">
+</pre>
+
+<p>Now when one of these configurations change, {@code MyActivity} is not restarted.
+Instead, the Activity receives a call to {@link
+android.app.Activity#onConfigurationChanged(Configuration) onConfigurationChanged()}. This method
+is passed a {@link android.content.res.Configuration} object that specifies
+the new device configuration. By reading fields in the {@link android.content.res.Configuration},
+you can determine the new configuration and make appropriate changes by updating
+the resources used in your interface. At the
+time this method is called, your Activity's {@link android.content.res.Resources} object is updated
+to return resources based on the new configuration, so you can easily
+reset elements of your UI without the system restarting your Activity.</p>
+
+<p>For example, the following {@link
+android.app.Activity#onConfigurationChanged(Configuration) onConfigurationChanged()} implementation
+checks the availability of a hardware keyboard and the current device orientation:</p>
+
+<pre>
+@Override
+public void onConfigurationChanged(Configuration newConfig) {
+ super.onConfigurationChanged(newConfig);
+
+ // Checks the orientation of the screen
+ if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
+ Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();
+ } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
+ Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show();
+ }
+ // Checks whether a hardware keyboard is available
+ if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_NO) {
+ Toast.makeText(this, "keyboard visible", Toast.LENGTH_SHORT).show();
+ } else if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_YES) {
+ Toast.makeText(this, "keyboard hidden", Toast.LENGTH_SHORT).show();
+ }
+}
+</pre>
+
+<p>The {@link android.content.res.Configuration} object represents all of the current
+configurations, not just the ones that have changed. Most of the time, you won't care exactly how
+the configuration has changed and can simply re-assign all your resources that provide alternatives
+to the configuration that you're handling. For example, because the {@link
+android.content.res.Resources} object is now updated, you can reset
+any {@link android.widget.ImageView}s with {@link android.widget.ImageView#setImageResource(int)}
+and the appropriate resource for the new configuration is used (as described in <a
+href="providing-resources.html#AlternateResources">Providing Resources</a>).</p>
+
+<p>Notice that the values from the {@link
+android.content.res.Configuration} fields are integers that are matched to specific constants
+from the {@link android.content.res.Configuration} class. For documentation about which constants
+to use with each field, refer to the appropriate field in the {@link
+android.content.res.Configuration} reference.</p>
+
+<p class="note"><strong>Remember:</strong> When you declare your Activity to handle a configuration
+change, you are responsible for resetting any elements for which you provide alternatives. If you
+declare your Activity to handle the orientation change and have images that should change
+between landscape and portrait, you must re-assign each resource to each element during {@link
+android.app.Activity#onConfigurationChanged(Configuration) onConfigurationChanged()}.</p>
+
+<p>If you don't need to update your application based on these configuration
+changes, you can instead <em>not</em> implement {@link
+android.app.Activity#onConfigurationChanged(Configuration) onConfigurationChanged()}. In
+which case, all of the resources used before the configuration change are still used
+and you've only avoided the restart of your Activity. However, your application should always be
+able to shutdown and restart with its previous state intact. Not only because
+there are other configuration changes that you cannot prevent from restarting your application but
+also in order to handle events such as when the user receives an incoming phone call and then
+returns to your application.</p>
+
+<p>For more about which configuration changes you can handle in your Activity, see the <a
+href="{@docRoot}guide/topics/manifest/activity-element.html#config">{@code
+android:configChanges}</a> documentation and the {@link android.content.res.Configuration}
+class.</p>

+
+<p>Here are a few important things you should know about how to properly
+format and style your string resources.</p>
+
+
+<h3>Escaping apostrophes and quotes</h3>
+
+<p>If you have an apostrophe or a quote in your string, you must either escape it or enclose the
+whole string in the other type of enclosing quotes. For example, here are some stings that
+do and don't work:</p>
+
+<pre>
+<string name="good_example">"This'll work"</string>
+<string name="good_example_2">This\'ll also work</string>
+<string name="bad_example">This doesn't work</string>
+<string name="bad_example_2">XML encodings don&apos;t work</string>
+</pre>
+
+
+<h3>Formatting strings</h3>
+
+<p>If you need to format your strings using <a
+href="{@docRoot}reference/java/lang/String.html#format(java.lang.String,
+java.lang.Object...)">{@code String.format(String, Object...)}</a>,
+then you can do so by putting
+your format arguments in the string resource. For example, with the following resource:</p>
+
+<pre>
+<string name="welcome_messages">Hello, %1$s! You have %2$d new messages.</string>
+</pre>
+
+<p>In this example, the format string has two arguments: {@code %1$s} is a string and {@code %2$d}
+is a decimal number. You can format the string with arguements from your application like this:</p>
+
+<pre>
+Resources res = {@link android.content.Context#getResources()};
+String text = String.<a href="{@docRoot}reference/java/lang/String.html#format(java.lang.String,
+java.lang.Object...)">format</a>(res.getString(R.string.welcome_messages), username, mailCount);
+</pre>
+
+
+
+<h3>Styling with HTML markup</h3>
+
+<p>You can add styling to your strings with HTML markup. For example:</p>
+<pre>
+<?xml version="1.0" encoding="utf-8"?>
+<resources>
+ <string name="welcome">Welcome to <b>Android</b>!</string>
+</resources>
+</pre>
+<p>Supported HTML elements include:</p>
+<ul>
+ <li>{@code <b>} for <b>bold</b> text.</li>
+ <li>{@code <i>} for <i>italic</i> text.</li>
+ <li>{@code <u>} for <u>underline</u> text.</li>
+</ul>
+
+<p>Sometimes you may want to create a styled text resource that is also used as a format
+string. Normally, this won't work because the <a
+href="{@docRoot}reference/java/lang/String.html#format(java.lang.String,
+java.lang.Object...)">{@code String.format(String, Object...)}</a>
+method will strip all the style
+information from the string. The work-around to this is to write the HTML tags with escaped
+entities, which are then recovered with {@link android.text.Html#fromHtml(String)},
+after the formatting takes place. For example:</p>
+
+<ol>
+ <li>Store your styled text resource as an HTML-escaped string:
+<pre>
+<resources>
+ <string name="welcome_messages">Hello, %1$s! You have &lt;b>%2$d new messages&lt;/b>.</string>
+</resources>
+</pre>
+<p>In this formatted string, a {@code <b>} element is added. Notice that the opening bracket is
+HTML-escaped, using the {@code &lt;} notation.</p>
+ </li>
+ <li>Then format the string as usual, but also call {@link android.text.Html#fromHtml} to
+convert the HTML text into styled text:
+<pre>
+Resources res = {@link android.content.Context#getResources()};
+String text = String.<a
+href="{@docRoot}reference/java/lang/String.html#format(java.lang.String,
+java.lang.Object...)">format</a>(res.getString(R.string.welcome_messages), username, mailCount);
+CharSequence styledText = Html.fromHtml(text);
+</pre>
+ </li>
+</ol>
+
+<p>Because the {@link android.text.Html#fromHtml} method will format all HTML entities, be sure to
+escape any possible HTML characters in the strings you use with the formatted text, using
+{@link android.text.TextUtils#htmlEncode}. For instance, if you'll be passing a string argument to
+<a href="{@docRoot}reference/java/lang/String.html#format(java.lang.String,
+java.lang.Object...)">{@code String.format()}</a> that may contain characters such as
+"<" or "&", then they must be escaped before formatting, so that when the formatted string
+is passed through {@link android.text.Html#fromHtml}, the characters come out the way they were
+originally written. For example:</p>
+<pre>
+String escapedUsername = TextUtil.{@link android.text.TextUtils#htmlEncode htmlEncode}(username);
+
+Resources res = {@link android.content.Context#getResources()};
+String text = String.<a href="{@docRoot}reference/java/lang/String.html#format(java.lang.String,
+java.lang.Object...)">format</a>(res.getString(R.string.welcome_messages), escapedUsername, mailCount);
+CharSequence styledText = Html.fromHtml(text);
+</pre>
+
