方向改变后过渡闪烁

Transition blink after orientation change

更新

我用 Google https://issuetracker.google.com/issues/63663775

打开了一个错误

我正在尝试在我当前的 Android 申请中雇用 makeSceneTransitionAnimation

我有一个来源 Activity,其中包含一个 Fragment,在片段中是一个 RecyclerView

当我单击 RecyclerView 中的图像时,我会转换到我的目标 Activity,其中包含一个片段,该片段可以正确显示具有可接受动画的图像。

按后退按钮可以正确反转动画。

以上在纵向和横向方向上都能正常工作。

当我在查看目标 Fragment 时改变方向然后按返回按钮时,会出现闪烁问题。

还有其他问题,例如图像没有 return 直接到其原始位置,并且在较旧的设备上我看到水平线,就像来自调谐不好的模拟电视的干扰。

闪烁非常糟糕,设备屏幕完全变黑大约 500 毫秒。

我已经下载并部署了 google 示例共享元素转换应用程序,它似乎具有相同的 "Feature"。

我尝试了多种解决方案,其中 none 个有效,例如

Here's 一个出现问题的。

我认为问题出在 ImageView layoutbounds 上,因为场景转换会计算起始位置和结束位置之间的差异,然后为差异设置动画,但是由于方向改变,这里的结束位置发生了变化,你能尝试重新创建结束位置吗在方向改变的情况下,一旦你按下布局可能是我错了,但只能想到这种情况,你能提供相同的代码吗?(这太大了,无法添加为评论,所以必须添加为答案.)

问题在于:您开始 Activity2 时处于纵向模式,然后返回 Activity1 时处于横向模式。但是因为您执行了方向更改,Activity1 的视图层次结构被破坏并创建,因此不再有最初开始转换的 View

您可以做的是使用 Activity#setExitSharedElementCallback() API. There's a bit of work to do to handle that situation though, which I've already described step-by-step in my 答案将旧视图重新映射到新视图。

您最好的选择是检查Alex Lockwood's app at github您需要的功能,这样您会更容易理解如何处理这种情况。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    setExitSharedElementCallback(new SharedElementCallback() {
        @Override
        public void onMapSharedElements(List<String> names, Map<String, View> sharedElements) {

            if (we are coming back to Activity1) {
                View newSharedElement = findViewById(R.id.your_imageview);
                if (newSharedElement != null) {
                    names.clear();
                    names.add("transition name");
                    sharedElements.clear();
                    sharedElements.put("transition name", newSharedElement);
                }
            } else {
                // we are leaving Activity1
            }
        }
    });
}

基本上,您正在清除地图并添加新的 "transition name-view" 对 给它。您可以看到 if (we are coming back to Activity1) 检查是如何完成的 here.


这是在 one of my apps 中实现的功能。

这似乎只发生在奥利奥上。它可以使用 Google 的示例项目在 API 26 模拟器上重现:https://github.com/googlesamples/android-ActivitySceneTransitionBasic/#readme

我通过添加以下内容成功解决了我的应用程序中的问题:

<item name="android:windowIsTranslucent">true</item>
