Public methods

onTransitionCancel

Added in 1.6.0-alpha01
public void onTransitionCancel(@NonNull Transition transition)

Notification about the cancellation of the transition. Note that cancel may be called by a parent TransitionSet on a child transition which has not yet started. This allows the child transition to restore state on target objects which was set at createAnimator() time.

Parameters
@NonNull Transition transition

The transition which was canceled.

onTransitionEnd

Added in 1.6.0-alpha01
public void onTransitionEnd(@NonNull Transition transition)

Notification about the end of the transition. Canceled transitions will always notify listeners of both the cancellation and end events. That is, onTransitionEnd is always called, regardless of whether the transition was canceled or played through to completion.

Parameters
@NonNull Transition transition

The transition which reached its end.

onTransitionPause

Added in 1.6.0-alpha01
public void onTransitionPause(@NonNull Transition transition)

Notification when a transition is paused. Note that createAnimator() may be called by a parent TransitionSet on a child transition which has not yet started. This allows the child transition to restore state on target objects which was set at createAnimator() time.

Parameters
@NonNull Transition transition

The transition which was paused.

onTransitionResume

Added in 1.6.0-alpha01
public void onTransitionResume(@NonNull Transition transition)

Notification when a transition is resumed. Note that resume() may be called by a parent TransitionSet on a child transition which has not yet started. This allows the child transition to restore state which may have changed in an earlier call to onTransitionPause.

Parameters
@NonNull Transition transition

The transition which was resumed.

onTransitionStart

Added in 1.6.0-alpha01
public void onTransitionStart(@NonNull Transition transition)

Notification about the start of the transition.

Parameters
@NonNull Transition transition

The started transition.
