Summary
Public methods | |
---|---|
abstract Unit |
onAnimationCancel(@NonNull animation: Animator) Notifies the cancellation of the animation. |
open Unit |
onAnimationEnd(@NonNull animation: Animator, isReverse: Boolean) Notifies the end of the animation. |
abstract Unit |
onAnimationEnd(@NonNull animation: Animator) Notifies the end of the animation. |
abstract Unit |
onAnimationRepeat(@NonNull animation: Animator) Notifies the repetition of the animation. |
open Unit |
onAnimationStart(@NonNull animation: Animator, isReverse: Boolean) Notifies the start of the animation as well as the animation's overall play direction. |
abstract Unit |
onAnimationStart(@NonNull animation: Animator) Notifies the start of the animation. |
Public methods
onAnimationCancel
abstract fun onAnimationCancel(@NonNull 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
open fun onAnimationEnd(
@NonNull 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(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. |
onAnimationEnd
abstract fun onAnimationEnd(@NonNull 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. |
onAnimationRepeat
abstract fun onAnimationRepeat(@NonNull animation: Animator): Unit
Notifies the repetition of the animation.
Parameters | |
---|---|
animation |
Animator: The animation which was repeated |
onAnimationStart
open fun onAnimationStart(
@NonNull 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(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. |
