# TransitionListenerAdapter

` public abstract class TransitionListenerAdapter `   
` extends https://developer.android.com/reference/java/lang/Object ` ` implements https://developer.android.com/reference/android/transition/Transition.TransitionListener `

*** ** * ** ***

This adapter class provides empty implementations of the methods from `https://developer.android.com/reference/android/transition/Transition.TransitionListener`. 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 constructors

### TransitionListenerAdapter

```
public TransitionListenerAdapter ()
```

<br />

<br />

## Public methods

### onTransitionCancel

Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public void onTransitionCancel (Transition transition)
```

Notification about the cancellation of the transition. Note that cancel may be called by a parent `https://developer.android.com/reference/android/transition/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 `https://developer.android.com/reference/android/transition/Transition#createAnimator(android.view.ViewGroup,%20android.transition.TransitionValues,%20android.transition.TransitionValues)` time.

<br />

| Parameters ||
|---|---|
| `transition` | `Transition`: The transition which was canceled. <br /> |

### onTransitionEnd

Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public void onTransitionEnd (Transition transition)
```

Notification about the end of the transition. Canceled transitions will always notify listeners of both the cancellation and end events. That is, `https://developer.android.com/reference/android/transition/Transition.TransitionListener#onTransitionEnd(android.transition.Transition)` is always called, regardless of whether the transition was canceled or played through to completion.

<br />

| Parameters ||
|---|---|
| `transition` | `Transition`: The transition which reached its end. <br /> |

### onTransitionPause

Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public void onTransitionPause (Transition transition)
```

Notification when a transition is paused. Note that createAnimator() may be called by a parent `https://developer.android.com/reference/android/transition/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 `https://developer.android.com/reference/android/transition/Transition#createAnimator(android.view.ViewGroup,%20android.transition.TransitionValues,%20android.transition.TransitionValues)` time.

<br />

| Parameters ||
|---|---|
| `transition` | `Transition`: The transition which was paused. <br /> |

### onTransitionResume

Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public void onTransitionResume (Transition transition)
```

Notification when a transition is resumed. Note that resume() may be called by a parent `https://developer.android.com/reference/android/transition/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 `https://developer.android.com/reference/android/transition/Transition.TransitionListener#onTransitionPause(android.transition.Transition)`.

<br />

| Parameters ||
|---|---|
| `transition` | `Transition`: The transition which was resumed. <br /> |

### onTransitionStart

Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public void onTransitionStart (Transition transition)
```

Notification about the start of the transition.

<br />

| Parameters ||
|---|---|
| `transition` | `Transition`: The started transition. <br /> |
