我在视图寻呼机VideoFragment和StoryFragment中有两个片段。 在Videofragment中，我设置以下行和视频视图以匹配父.-
getActivity().getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_LOW_PROFILE
| View.SYSTEM_UI_FLAG_IMMERSIVE);
getActivity().getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
用户移动到肖像后我正在清除标志 -
metrics2 = new DisplayMetrics();
getActivity().getWindow().getDecorView()
.setSystemUiVisibility(View.SYSTEM_UI_FLAG_IMMERSIVE);
getActivity().getWindowManager().getDefaultDisplay().getMetrics(metrics2);
getActivity().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
所有这些都发生在VideoFragment中，但是当我滑动视图寻呼机时，下一个片段是具有以下布局的故事片段 -

Webview占据整个屏幕，将所有视图移至顶部。当我向下滚动时，我可以看到图像。只有当我在视频片段中进入横向模式时才会发生这种情况。我正在使用Exoplayer播放视频。
修改1
现在我将<ScrollView>更改为<NestedScrollView>并添加了此属性android：fillViewport =＆＃34; true＆＃34; 。
从风景画回到画像后，它不会崩溃但滚动不起作用。
