MediaRouteActionProvider

If overridesItemVisibility() returns true, the return value of this method will help determine the visibility of the MenuItem this ActionProvider is bound to.

If the MenuItem's visibility is explicitly set to false by the application, the MenuItem will not be shown, even if this method returns true.

Factory method called by the Android framework to create new action views.

This method has been deprecated in favor of onCreateActionView(MenuItem). Newer apps that wish to support platform versions prior to API 16 should also implement this method to return a valid action view.

Factory method called by the Android framework to create new action views. This method returns a new action view for the given MenuItem.

If your ActionProvider implementation overrides the deprecated no-argument overload onCreateActionView(), overriding this method for devices running API 16 or later is recommended but optional. The default implementation calls onCreateActionView() for compatibility with applications written for older platform versions.

Performs an optional default action.

For the case of an action provider placed in a menu item not shown as an action this method is invoked if previous callbacks for processing menu selection has handled the event.

A menu item selection is processed in the following order:

• Receiving a call to MenuItem.OnMenuItemClickListener.onMenuItemClick.
• Receiving a call to Activity.onOptionsItemSelected(MenuItem)
• Receiving a call to Fragment.onOptionsItemSelected(MenuItem)
• Launching the Intent set via MenuItem.setIntent(android.content.Intent)
• Invoking this method.

The default implementation does not perform any action and returns false.

The result of this method determines whether or not isVisible() will be used by the MenuItem this ActionProvider is bound to help determine its visibility.
