TransitionListenerAdapter
abstract class TransitionListenerAdapter : Transition.TransitionListener
This adapter class provides empty implementations of the methods from . Any custom listener that cares only about a subset of the methods of this listener can simply subclass this adapter class instead of implementing the interface directly.

Public methods
onTransitionCancel
open fun onTransitionCancel(transition: Transition!): Unit
Notification about the cancellation of the transition. Note that cancel may be called by a parent TransitionSet on a child transition which has not yet started. This allows the child transition to restore state on target objects which was set at createAnimator() time.
| Parameters |
transition |
Transition!: The transition which was canceled. |
onTransitionEnd
open fun onTransitionEnd(transition: Transition!): Unit
Notification about the end of the transition. Canceled transitions will always notify listeners of both the cancellation and end events. That is, onTransitionEnd(android.transition.Transition) is always called, regardless of whether the transition was canceled or played through to completion.
| Parameters |
transition |
Transition!: The transition which reached its end. |
onTransitionPause
open fun onTransitionPause(transition: Transition!): Unit
Notification when a transition is paused. Note that createAnimator() may be called by a parent TransitionSet on a child transition which has not yet started. This allows the child transition to restore state on target objects which was set at createAnimator() time.
| Parameters |
transition |
Transition!: The transition which was paused. |
onTransitionResume
open fun onTransitionResume(transition: Transition!): Unit
Notification when a transition is resumed. Note that resume() may be called by a parent TransitionSet on a child transition which has not yet started. This allows the child transition to restore state which may have changed in an earlier call to onTransitionPause(android.transition.Transition).
| Parameters |
transition |
Transition!: The transition which was resumed. |
onTransitionStart
open fun onTransitionStart(transition: Transition!): Unit
Notification about the start of the transition.
| Parameters |
transition |
Transition!: The started transition. |
