Known Direct Subclasses

AnimatorListenerAdapter

This adapter class provides empty implementations of the methods from android.animation.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 methods
abstract Unit	`onAnimationCancel(animation: Animator)` Notifies the cancellation of the animation.
abstract Unit	`onAnimationEnd(animation: Animator)` Notifies the end of the animation.
open Unit	`onAnimationEnd(animation: Animator, isReverse: Boolean)` Notifies the end of the animation.
abstract Unit	`onAnimationRepeat(animation: Animator)` Notifies the repetition of the animation.
abstract Unit	`onAnimationStart(animation: Animator)` Notifies the start of the animation.
open Unit	`onAnimationStart(animation: Animator, isReverse: Boolean)` Notifies the start of the animation as well as the animation's overall play direction.

Public methods

onAnimationCancel

Added in API level 11

abstract 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. This value cannot be `null`.

onAnimationEnd

Added in API level 11

abstract 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. This value cannot be `null`.

onAnimationEnd

Added in API level 26

open 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(android.animation.Animator). 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(android.animation.Animator) not getting called.

Parameters
`animation`	Animator: The animation which reached its end. This value cannot be `null`.
`isReverse`	Boolean: Whether the animation is playing in reverse.

onAnimationRepeat

Added in API level 11

abstract fun onAnimationRepeat(animation: Animator): Unit

Notifies the repetition of the animation.

Parameters
`animation`	Animator: The animation which was repeated. This value cannot be `null`.

onAnimationStart

Added in API level 11

abstract fun onAnimationStart(animation: Animator): Unit

Notifies the start of the animation.

Parameters
`animation`	Animator: The started animation. This value cannot be `null`.

onAnimationStart

Added in API level 26

open 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(android.animation.Animator). 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(android.animation.Animator) not getting called.

Parameters
`animation`	Animator: The started animation. This value cannot be `null`.
`isReverse`	Boolean: Whether the animation is playing in reverse.
