Known direct subclasses

AnimatorListenerAdapter

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 methods
`abstract void`	`onAnimationCancel(@NonNull Animator animation)` Notifies the cancellation of the animation.
`abstract void`	`onAnimationEnd(@NonNull Animator animation)` Notifies the end of the animation.
`default void`	`onAnimationEnd(@NonNull Animator animation, boolean isReverse)` Notifies the end of the animation.
`abstract void`	`onAnimationRepeat(@NonNull Animator animation)` Notifies the repetition of the animation.
`abstract void`	`onAnimationStart(@NonNull Animator animation)` Notifies the start of the animation.
`default void`	`onAnimationStart(@NonNull Animator animation, boolean isReverse)` Notifies the start of the animation as well as the animation's overall play direction.

Public methods

onAnimationCancel

abstract void onAnimationCancel(@NonNull Animator animation)

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

Parameters
`@NonNull Animator animation`	The animation which was canceled.

onAnimationEnd

abstract void onAnimationEnd(@NonNull Animator animation)

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

Parameters
`@NonNull Animator animation`	The animation which reached its end.

onAnimationEnd

default void onAnimationEnd(@NonNull Animator animation, boolean isReverse)

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
`@NonNull Animator animation`	The animation which reached its end.
`boolean isReverse`	Whether the animation is playing in reverse.

onAnimationRepeat

abstract void onAnimationRepeat(@NonNull Animator animation)

Notifies the repetition of the animation.

Parameters
`@NonNull Animator animation`	The animation which was repeated

onAnimationStart

abstract void onAnimationStart(@NonNull Animator animation)

Notifies the start of the animation.

Parameters
`@NonNull Animator animation`	The started animation.

onAnimationStart

default void onAnimationStart(@NonNull Animator animation, boolean isReverse)

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
`@NonNull Animator animation`	The started animation.
`boolean isReverse`	Whether the animation is playing in reverse.
