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][1] API provided
|
||
in API 11 or above. Support for older devices is provided by the
|
||
[support library’s ActionBar][2] 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 AppCompatActivity.
|
||
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.
