Public Methods

public abstract Rect onGetEpicenter (Transition transition)

Implementers must override to return the epicenter of the Transition in screen coordinates. Transitions like Explode depend upon an epicenter for the Transition. In Explode, Views move toward or away from the center of the epicenter Rect along the vector between the epicenter and the center of the View appearing and disappearing. Some Transitions, such as Fade pay no attention to the epicenter.

Parameters

transition	The transition for which the epicenter applies.

Returns

The Rect region of the epicenter of transition or null if there is no epicenter.
