A transition listener receives notifications from a transition. Notifications indicate transition lifecycle events.

Summary

Public methods

abstract void onTransitionCancel(Transition transition)

Notification about the cancellation of the transition.

abstract void onTransitionEnd(Transition transition)

Notification about the end of the transition.

abstract void onTransitionPause(Transition transition)

Notification when a transition is paused.

abstract void onTransitionResume(Transition transition)

Notification when a transition is resumed.

abstract void onTransitionStart(Transition transition)

Notification about the start of the transition.

Public methods

onTransitionCancel

public abstract void onTransitionCancel (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
transition Transition: The transition which was canceled.

onTransitionEnd

public abstract void onTransitionEnd (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(Transition) is always called, regardless of whether the transition was canceled or played through to completion.

Parameters
transition Transition: The transition which reached its end.

onTransitionPause

public abstract void onTransitionPause (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
transition Transition: The transition which was paused.

onTransitionResume

public abstract void onTransitionResume (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(Transition).

Parameters
transition Transition: The transition which was resumed.

onTransitionStart

public abstract void onTransitionStart (Transition transition)

Notification about the start of the transition.

Parameters
transition Transition: The started transition.
