我有两个活动,只有一个共享对象,一个ImageView.这两个活动都是子类,AppCompatActivity它们共享相同的主题:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:windowActionBar">false</item>
    <item name="android:windowContentTransitions">true</item>
    <item name="android:windowTranslucentStatus">false</item>
    <item name="android:windowExitTransition">@transition/transition_slide</item>
    <item name="android:windowEnterTransition">@transition/transition_slide</item>
    <!-- specify shared element transitions -->
    <item name="android:windowSharedElementEnterTransition">
        @transition/obj_transition</item>
    <item name="android:windowSharedElementExitTransition">
        @transition/obj_transition</item>
</style>

活动A按以下方式调用活动B:

Intent intent = new Intent(ActivityA.this, ActivityB.class);
ActivityOptionsCompat options = ActivityOptionsCompat
    .makeSceneTransitionAnimation(ActivityA.this, view, "common_tag");
ActivityCompat
    .startActivityForResult(ActivityA.this, intent, ACT_B_TAG, options.toBundle());

在Activity B上,我想在同一个共享的ImageView上启动一个简单的摆动动画.如果我在onCreate方法上启动动画,结果非常难看,因为它在活动转换结束之前开始.所以我覆盖了onEnterAnimationComplete()Activity B中的方法:

@Override
public void onEnterAnimationComplete() {
    Log.d(TAG, "ANIMATION COMPLETE");
    Animation …
