android – 为什么我的全屏webview在打开后会立即关闭？

我的全屏视频网页视图几乎总是在打开后立即关闭,有时它可以正常工作.几乎每次我点击youtube视频上的全屏按钮时,您都可以看到屏幕闪烁到全屏并恢复原状.这可能是什么原因？

webview显示在tablayout / viewpager设置中,其中包含一些其他片段.

我用这段代码来显示视频：

现在我正在使用这个https://github.com/GoogleChrome/chromium-webview-samples/blob/master/fullscreen-video-sample/app/src/main/java/fullscreenvideosample/android/chrome/google/com/fullscreenvideosample/MainActivity.java

它们产生完全相同的行为.

全屏失败时记录并在打开后立即恢复正常：

编辑：
它似乎只在youtube上发生.测试过Vimeo和youtube. Vimeo每次都会打开.

解决方法

我能想到的最好的事情是你的设备没有内存.所以我有一些建议给你.

>首先,当你的所有ram都是空闲的时候在你的设备上测试它并检查结果.
>其次,你已经提到你有一个Galaxy S6和一个Galaxy S3,在两个设备上运行你的应用程序.
>如果您可以在另一台Galaxy S6上测试您的应用并查看它是否重复,那么它非常有用.

收集这些信息后,您可以找到解决问题的方法.

您可以测试的另一件事是使用android：hardwareAccelerated =“true”并检查它是否有帮助.
