Animator.AnimatorListener

interface Animator.AnimatorListener

Known direct subclasses
AnimatorListenerAdapter

This adapter class provides empty implementations of the methods from Animator.AnimatorListener.


An animation listener receives notifications from an animation. Notifications indicate animation related events, such as the end or the repetition of the animation.

Summary

Public functions

Unit

Notifies the cancellation of the animation.

Unit

Notifies the end of the animation.

Unit
onAnimationEnd(animation: Animator, isReverse: Boolean)

Notifies the end of the animation.

Unit

Notifies the repetition of the animation.

Unit

Notifies the start of the animation.

Unit
onAnimationStart(animation: Animator, isReverse: Boolean)

Notifies the start of the animation as well as the animation's overall play direction.

Public functions

onAnimationCancel

fun onAnimationCancel(animation: Animator): Unit

Notifies the cancellation of the animation. This callback is not invoked for animations with repeat count set to INFINITE.

Parameters
animation: Animator

The animation which was canceled.

onAnimationEnd

fun onAnimationEnd(animation: Animator): Unit

Notifies the end of the animation. This callback is not invoked for animations with repeat count set to INFINITE.

Parameters
animation: Animator

The animation which reached its end.

onAnimationEnd

fun onAnimationEnd(animation: Animator, isReverse: Boolean): Unit

Notifies the end of the animation. This callback is not invoked for animations with repeat count set to INFINITE.

This method's default behavior is to call onAnimationEnd. This method can be overridden, though not required, to get the additional play direction info when an animation ends. Skipping calling super when overriding this method results in onAnimationEnd not getting called.

Parameters
animation: Animator

The animation which reached its end.

isReverse: Boolean

Whether the animation is playing in reverse.

onAnimationRepeat

fun onAnimationRepeat(animation: Animator): Unit

Notifies the repetition of the animation.

Parameters
animation: Animator

The animation which was repeated

onAnimationStart

fun onAnimationStart(animation: Animator): Unit

Notifies the start of the animation.

Parameters
animation: Animator

The started animation.

onAnimationStart

fun onAnimationStart(animation: Animator, isReverse: Boolean): Unit

Notifies the start of the animation as well as the animation's overall play direction. This method's default behavior is to call onAnimationStart. This method can be overridden, though not required, to get the additional play direction info when an animation starts. Skipping calling super when overriding this method results in onAnimationStart not getting called.

Parameters
animation: Animator

The started animation.

isReverse: Boolean

Whether the animation is playing in reverse.
