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 Android.Views.IMenuItem 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:

• Set the action provider on a Android.Views.IMenuItem directly by calling IMenuItem.SetActionProvider(ActionProvider).
• Declare the action provider in an XML menu resource. For example:

  xml Example

     <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" />
