Remarks
An ActionProvider defines rich menu interaction in a single component. ActionProvider can generate action views for use in the action bar, dynamically populate submenus of a MenuItem, and handle default menu item invocations.
An ActionProvider can be optionally specified for a MenuItem and will be responsible for creating the action view that appears in the android.app.ActionBar in place of a simple button in the bar. When the menu item is presented in a way that does not allow custom action views, (e.g. in an overflow menu,) the ActionProvider can perform a default action.
There are two ways to use an action provider: <ul> <li> Set the action provider on a MenuItem directly by calling MenuItem#setActionProvider(ActionProvider). </li> <li> Declare the action provider in an XML menu resource. For example:
<code>
<item android:id="@+id/my_menu_item"
android:title="Title"
android:icon="@drawable/my_menu_item_icon"
android:showAsAction="ifRoom"
android:actionProviderClass="foo.bar.SomeActionProvider" />
</code>
</li> </ul> </p>
