Remarks

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: <ul> <li> Receiving a call to MenuItem.OnMenuItemClickListener#onMenuItemClick MenuItem.OnMenuItemClickListener.onMenuItemClick. </li> <li> Receiving a call to android.app.Activity#onOptionsItemSelected(MenuItem) Activity.onOptionsItemSelected(MenuItem)</li> <li> Receiving a call to android.app.Fragment#onOptionsItemSelected(MenuItem) Fragment.onOptionsItemSelected(MenuItem)</li> <li> Launching the android.content.Intent set via MenuItem#setIntent(android.content.Intent) MenuItem.setIntent(android.content.Intent)</li> <li> Invoking this method. </li> </ul>

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