在活动的图像过渡闪屏 [英] Blinking screen on image transition between activities

问题描述

我实现了利用棒棒糖新的共享元素两项活动之间的图像转换。它的工作，但我得到一个奇怪的白色过渡期间闪烁在整个屏幕上，我无法找到如何摆脱它。下面是一个例子：

I implemented an image transition between two activities using the new shared elements from lollipop. It's working but I get a weird white blinking on the entire screen during the transition and I can't find how to get rid of it. Here is an example:

下面是如何在第二个活动启动

Here is how the second activity is launched

public static void launch(
            @NonNull Activity activity, @NonNull View transitionView, Game game) {
        ActivityOptionsCompat options =
                ActivityOptionsCompat.makeSceneTransitionAnimation(
                        activity, transitionView, game.gameFullId);
        Intent intent = new Intent(activity, ListImportationLoginActivity.class);
        intent.putExtra(INTENT_EXTRA_GAME, retailer);
        ActivityCompat.startActivity(activity, intent, options.toBundle());
    }

然后在的onCreate：

Then in onCreate:

ViewCompat.setTransitionName(mLogoView, mGame.gameFullId);  

和主题文件：

<resources>
    <style name="Theme.MyApp.NoActionBar" parent="Theme.MyApp.NoActionBar.Base">
        <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>
    </style>
</resources>

推荐答案

白色闪烁你看到的是进出过渡期间，两项活动的α-动画的结果是：如果活动 A 启动活动 B ，活性 A 淡出和活动乙淡入

The "white blinking" you are seeing is the result of the two activities alpha-animating in and out during the transition: when activity A starts activity B, activity A fades out and activity B fades in.

如果你想prevent从过渡时期衰落（并因此减少了闪烁的效果了一下），你可以看看的this帖子。

If you want to prevent the status bar and/or navigation bar from fading during the transition (and thus reducing the "blinking" effect a bit), you can look at this post.
