android - 为什么我的全屏 webview 在打开后立即不断关闭？

Question

我的全屏视频 webview 几乎总是在打开后立即关闭，有时它会起作用。几乎每次我在 youtube 视频上单击全屏按钮时，您都可以看到屏幕闪烁到全屏并返回原始屏幕。这可能是什么原因？

webview 与其他一些 fragment 一起显示在 tablayout/viewpager 设置中。

我使用这段代码来显示视频: https://github.com/cprcrack/VideoEnabledWebView

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。

当全屏失败并在打开后立即恢复正常时记录:

编辑:它似乎只发生在 youtube 上。测试了 Vimeo 与 youtube。 Vimeo 每次都会打开。

Answer 1

我能想到的最好的事情是你的设备没有内存了。所以我有一些建议给你。

• 首先，当所有 ram 都空闲时，在您的设备上测试它并检查结果。

• 其次，您提到您拥有 Galaxy S6 和 Galaxy S3，请在这两种设备上运行您的应用程序。

• 此外，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，这将非常有帮助。

收集这些信息后，您也许能够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。
