Public methods

onTransitionCancel

Added in API level 26

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

Added in API level 26

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

Added in API level 26

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

Added in API level 26

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

Added in API level 26

open fun onTransitionStart(transition: Transition!): Unit

Notification about the start of the transition.

Parameters
`transition`	Transition!: The started transition.
