### 分解

```
public static void start ( Context context ) {
      Intent starter = new Intent( context, ExplodeActivity.class );
      context.startActivity(
          starter,
          ActivityOptionsCompat.makeSceneTransitionAnimation( (Activity) context ).toBundle()
      );
}
```

```
getWindow().setEnterTransition( new Explode().setDuration( 2000 ) );
getWindow().setExitTransition( new Explode().setDuration( 2000 ) );
```

### 滑入

```
public static void start ( Context context ) {
      Intent starter = new Intent( context, SlideActivity.class );
      context.startActivity(
          starter,
          ActivityOptionsCompat.makeSceneTransitionAnimation( (Activity) context ).toBundle()
      );
}
```

```
Slide slide = new Slide();
slide.setSlideEdge( Gravity.START );
getWindow().setEnterTransition( slide.setDuration( 2000 ) );
getWindow().setExitTransition( slide.setDuration( 2000 ) );
```

### 渐隐

```
public static void start ( Context context ) {
      Intent starter = new Intent( context, FadeActivity.class );
      context.startActivity(
          starter,
          ActivityOptionsCompat.makeSceneTransitionAnimation( (Activity) context ).toBundle()
      );
}
```

```
Fade slide = new Fade();
getWindow().setEnterTransition( slide.setDuration( 2000 ) );
getWindow().setExitTransition( slide.setDuration( 2000 ) );

## 共享元素

* 两个不同界面之间设置transitionName

```
<ImageView
    android:id="@+id/imageView"
    android:layout_width="200dp"
    android:layout_height="200dp"
    android:layout_marginTop="8dp"
    android:layout_marginStart="8dp"
    android:onClick="shareImage"
    android:scaleType="centerCrop"
    android:src="@drawable/a"
    android:transitionName="image"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/button5"
    />
```

```
<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:src="@drawable/b"
    android:transitionName="image">
</ImageView>
```

```
Intent starter = new Intent( context, ShareElementActivity.class );
context.startActivity(
    starter,
    ActivityOptionsCompat
        .makeSceneTransitionAnimation( (Activity) context, view, transitionName )	-->view 及 transitionName
        .toBundle()
