Callback2


abstract class Callback2 : ActionMode.Callback

Extension of ActionMode.Callback to provide content rect information. This is required for ActionModes with dynamic positioning such as the ones with type ActionMode.TYPE_FLOATING to ensure the positioning doesn't obscure app content. If an app fails to provide a subclass of this class, a default implementation will be used.

Parameters
mode ActionMode!: The ActionMode that requires positioning.
view View!: The View that originated the ActionMode, in whose coordinates the Rect should be provided.
