我自己找到了答案，这是ReactExoPlayerView的全屏集成

private void openFullscreenDialog() {
        activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE);
        ((ViewGroup) exoPlayerView.getParent()).removeView(exoPlayerView);
        if (playerControlView.getParent() != null) {
            ((ViewGroup) playerControlView.getParent()).removeView(playerControlView); // <- fix
        }
        exoPlayerView.addView(playerControlView);
        mFullScreenDialog = new Dialog(themedReactContext,android.R.style.Theme_Black_NoTitleBar_Fullscreen);
        mFullScreenDialog.addContentView(exoPlayerView,new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT));
        mFullScreenDialog.setCancelable(false);
        mFullScreenDialog.setOnKeyListener((dialog,keyCode,event) -> {
            if (event.getAction() == KeyEvent.ACTION_UP && keyCode == KeyEvent.KEYCODE_BACK) {
                if (isFullscreen) {
                    fullScreenButtonClick();
                }
                return true;
            } else {
                return false;

            }
        });
        mFullScreenDialog.show();
    }

private void closeFullscreenDialog() {
          activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        ((ViewGroup) exoPlayerView.getParent()).removeView(exoPlayerView);
        if (playerControlView.getParent() != null) {
            ((ViewGroup) playerControlView.getParent()).removeView(playerControlView); // <- fix
        }
        addView(exoPlayerView);
        setControls(true);
        mFullScreenDialog.dismiss();
    }

希望它将对某人有所帮助
