Overview

Callback interface for action modes. Supplied to AppCompatDelegate (Callback)}, a Callback configures and handles events raised by a user's interaction with an action mode.

An action mode's lifecycle is as follows:

• ActionMode.Callback.onCreateActionMode(ActionMode, Menu) once on initial creation
• ActionMode.Callback.onPrepareActionMode(ActionMode, Menu) after creation and any time the ActionMode is invalidated
• ActionMode.Callback.onActionItemClicked(ActionMode, MenuItem) any time a contextual action button is clicked
• ActionMode.Callback.onDestroyActionMode(ActionMode) when the action mode is closed
