public interface Transition.TransitionListener
TransitionListenerAdapter |
This adapter class provides empty implementations of the methods from . |
A transition listener receives notifications from a transition. Notifications indicate transition lifecycle events.
Summary
Public methods |
|
|---|---|
abstract void |
onTransitionCancel(@NonNull Transition transition)Notification about the cancellation of the transition. |
abstract void |
onTransitionEnd(@NonNull Transition transition)Notification about the end of the transition. |
default void |
onTransitionEnd(@NonNull Transition transition, boolean isReverse)Notification about the end of the transition. |
abstract void |
onTransitionPause(@NonNull Transition transition)Notification when a transition is paused. |
abstract void |
onTransitionResume(@NonNull Transition transition)Notification when a transition is resumed. |
abstract void |
onTransitionStart(@NonNull Transition transition)Notification about the start of the transition. |
default void |
onTransitionStart(@NonNull Transition transition, boolean isReverse)Notification about the start of the transition. |
Public methods
onTransitionCancel
abstract void onTransitionCancel(@NonNull Transition transition)
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 | |
|---|---|
@NonNull Transition transition |
The transition which was canceled. |
onTransitionEnd
abstract void onTransitionEnd(@NonNull Transition transition)
Notification about the end of the transition. Canceled transitions will always notify listeners of both the cancellation and end events. That is, onTransitionEnd is always called, regardless of whether the transition was canceled or played through to completion.
| Parameters | |
|---|---|
@NonNull Transition transition |
The transition which reached its end. |
onTransitionEnd
default void onTransitionEnd(@NonNull Transition transition, boolean isReverse)
Notification about the end of the transition. Canceled transitions will always notify listeners of both the cancellation and end events. That is, onTransitionEnd is always called, regardless of whether the transition was canceled or played through to completion. Canceled transitions will have isReverse set to false.
| Parameters | |
|---|---|
@NonNull Transition transition |
The transition which reached its end. |
boolean isReverse |
|
onTransitionPause
abstract void onTransitionPause(@NonNull Transition transition)
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 | |
|---|---|
@NonNull Transition transition |
The transition which was paused. |
onTransitionResume
abstract void onTransitionResume(@NonNull Transition transition)
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.
| Parameters | |
|---|---|
@NonNull Transition transition |
The transition which was resumed. |
onTransitionStart
abstract void onTransitionStart(@NonNull Transition transition)
Notification about the start of the transition.
| Parameters | |
|---|---|
@NonNull Transition transition |
The started transition. |
onTransitionStart
default void onTransitionStart(@NonNull Transition transition, boolean isReverse)
Notification about the start of the transition.
| Parameters | |
|---|---|
@NonNull Transition transition |
The started transition. |
boolean isReverse |
