- sceneRoot
- ViewGroup
The root of the transition hierarchy
- view
- View
The View to make disappear. This will be in the target scene's View
hierarchy or in an android.view.ViewGroupOverlay and will be
VISIBLE.
- startValues
- TransitionValues
The target values in the start scene
- endValues
- TransitionValues
The target values in the end scene
Returns
An Animator to be started at the appropriate time in the overall transition for this scene change. A null value means no animation should be run.
- Attributes
Remarks
The default implementation of this method returns a null Animator. Subclasses should override this method to make targets disappear with the desired transition. The method should only be called from #onDisappear(ViewGroup, TransitionValues, int, TransitionValues, int).

Subclasses should override this method or
#onDisappear(ViewGroup, View, TransitionValues, TransitionValues)
if they need to create an Animator when targets disappear.

Remarks
Subclasses should override this method or #onDisappear(ViewGroup, View, TransitionValues, TransitionValues) if they need to create an Animator when targets disappear. The method should only be called by the Visibility class; it is not intended to be called from external classes.
The default implementation of this method attempts to find a View to use to call #onDisappear(ViewGroup, View, TransitionValues, TransitionValues), based on the situation of the View in the View hierarchy. For example, if a View was simply removed from its parent, then the View will be added into a android.view.ViewGroupOverlay and passed as the view parameter in #onDisappear(ViewGroup, View, TransitionValues, TransitionValues). If a visible View is changed to be View#GONE or View#INVISIBLE, then it can be used as the view and the visibility will be changed to View#VISIBLE for the duration of the animation. However, if a View is in a hierarchy which is also altering its visibility, the situation can be more complicated. In general, if a view that is no longer in the hierarchy in the end scene still has a parent (so its parent hierarchy was removed, but it was not removed from its parent), then it will be left alone to avoid side-effects from improperly removing it from its parent. The only exception to this is if the previous Scene was Scene#getSceneForLayout(ViewGroup, int, android.content.Context) created from a layout resource file, then it is considered safe to un-parent the starting scene view in order to make it disappear.
