/**
* A user interface element that displays text to the user.
* To provide user-editable text, see {@link EditText}.
* <p>
* The following code sample shows a typical use, with an XML layout
* and code to modify the contents of the text view:
* </p>
* <pre>
* &lt;LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"&gt;
* &lt;TextView
* android:id="@+id/text_view_id"
* android:layout_height="wrap_content"
* android:layout_width="wrap_content"
* android:text="@string/hello" /&gt;
* &lt;/LinearLayout&gt;
* </pre>
* <p>
* This code sample demonstrates how to modify the contents of the text view
* defined in the previous XML layout:
* </p>
* <pre>
* public class MainActivity extends Activity {
*
* protected void onCreate(Bundle savedInstanceState) {
* super.onCreate(savedInstanceState);
* setContentView(R.layout.activity_main);
* final TextView helloTextView = (TextView) findViewById(R.id.text_view_id);
* helloTextView.setText(R.string.user_greeting);
* }
* }
* </pre>
* <p>
