Question

我正在制作一个应用程序，当我在纵向模式下点击视频时，我应该以横向模式打开视频视图。我计划添加一个片段来做到这一点，但我想保留上一个视图中所有内容的状态，这样就不会中断调用。有没有办法做到这一点？这是我的片段代码：

public class SecureRoomCallFragment extends BaseCallFragment {

ViewGroup callStatusContainer;
@BindView(R.id.callNameText)

以下代码可能对您有所帮助：

 private void exitFullScreen() {
        isFullScreen = false;
        btnFullScreen.setImageResource(R.drawable.ic_full_screen);
        rlBottom.setVisibility(View.VISIBLE);
        ((DrawerLocker) getActivity()).setDrawerEnabled(true);
        ((MainModuleActivity) getActivity()).getSupportActionBar().show();
        DisplayMetrics metrics = new DisplayMetrics();
        getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        getActivity().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
        getActivity().getWindowManager().getDefaultDisplay().getMetrics(metrics);
        RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) videoView.getLayoutParams();
        params.leftMargin = 30;
        videoView.setLayoutParams(params);
    }

    private void viewFullScreen() {
        isFullScreen = true;
        btnFullScreen.setImageResource(R.drawable.ic_small_screen);
        rlBottom.setVisibility(View.GONE);
        ((MainModuleActivity) getActivity()).getSupportActionBar().hide();
        getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        getActivity().getWindow().setFlags(
                WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        ((DrawerLocker) getActivity()).setDrawerEnabled(false);
        DisplayMetrics displaymetrics = new DisplayMetrics();
        getActivity().getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
        int height = displaymetrics.heightPixels;
        int width = displaymetrics.widthPixels;
        RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) videoView.getLayoutParams();
        params.width = params.MATCH_PARENT;
        params.height = params.MATCH_PARENT;
        params.setMargins(0, 0, 0, 0);
    }

如何创建一个新片段，在最大化时从上一个片段打开全屏视频视图？
