Android ActionBarCompat-Basic Sample

This sample shows you how to use ActionBarCompat to create a basic Activity which displays action items. It covers inflating items from a menu resource, as well as adding an item in code.

Introduction

Android 3.0 introduced the “action bar” control, a toolbar that is expected to be present in most types of applications. This control identifies the user location, and provides user actions and navigation modes. Using the action bar offers your users a familiar interface across applications that the system gracefully adapts for different screen configurations.

Instantiating an action bar can be done by using the ActionBar API provided in API 11 or above. Support for older devices is provided by the support library’s ActionBar implementation, compatible back to API 7. This sample demonstrates using the support library APIs.

Using an ActionBar with the support library requires the following steps:

  1. Create your activity by extending ActionBarActivity.
  2. Use (or extend) one of the Theme.AppCompat themes for your activity.

Once this is done, action items will be created for any options menu items that would otherwise be created during when [onCreateOptionsMenu()][3] is called.
