我在 Lollipop 上的共享元素转换中看到了奇怪的东西。共享元素在开始动画之前闪烁（请参见视频https://www.youtube.com/watch?v=DCoyyC_S-9A）

我不知道为什么会这样。但是，当我添加<item name="android:windowSharedElementsUseOverlay">false</item>到我的主题时，我看不到闪烁，但过渡看起来并不好（它们看起来只有一半在动画“隐藏”动画的后半部分）。

其他过渡设置：

<item name="android:windowActivityTransitions">true</item>
<item name="android:windowContentTransitions">true</item>
<item name="android:windowAllowEnterTransitionOverlap">true</item>
<item name="android:windowAllowReturnTransitionOverlap">true</item>
<item name="android:windowSharedElementEnterTransition">@android:transition/move</item>
<item name="android:windowSharedElementExitTransition">@android:transition/move</item>

我正在使用 ActivityCompat 和 ActivityOptionsCompat 开始活动：

ActivityOptionsCompat options = ActivityOptionsCompat.makeSceneTransitionAnimation(ActivityMain.this,
                        new Pair<View, String>(playButton, getString(R.string.translation_control_button)),
                        new Pair<View, String>(findViewById(R.id.playerImage), getString(R.string.translation_artwork)));

ActivityCompat.startActivity(this, pendingIntent, options.toBundle());

第一项活动：

你有什么想法为什么会发生？

欢呼！我已经设法解决了这个问题。

闪烁屏幕是这里描述的常见问题：在活动之间的图像转换上闪烁屏幕（谢谢@AlexLockwood）

闪烁共享元素是由 DrawerLayout 引起的。我很快就开始了新的活动。当我转向ActivityCompat.startActivity' DrawerLayout.DrawerListenersonDrawerClosed方法时，一切都开始像魅力一样工作。
