abstract void onAnimationEnd(Animator animation)

Notifies the end of the animation.

default void onAnimationEnd(Animator animation, boolean isReverse)

Notifies the end of the animation.

abstract void onAnimationRepeat(Animator animation)

Notifies the repetition of the animation.

default void onAnimationStart(Animator animation, boolean isReverse)

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

abstract void onAnimationStart(Animator animation)

Notifies the start of the animation.

Public methods

onAnimationCancel

public abstract void onAnimationCancel (Animator animation)

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

public abstract void onAnimationEnd (Animator animation)

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

public void onAnimationEnd (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(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(Animator) not getting called.

Parameters
animation Animator: The animation which reached its end.

isReverse boolean: Whether the animation is playing in reverse.

onAnimationRepeat

public abstract void onAnimationRepeat (Animator animation)

Notifies the repetition of the animation.

Parameters
animation Animator: The animation which was repeated

onAnimationStart

public void onAnimationStart (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(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(Animator) not getting called.

Parameters
animation Animator: The started animation.

isReverse boolean: Whether the animation is playing in reverse.

onAnimationStart

public abstract void onAnimationStart (Animator animation)

Notifies the start of the animation.

Parameters
animation Animator: The started animation.
