Youtube 退出全屏模式 TextView 可见性问题

我正在全屏模式下播放视频，当我单击后退按钮时，我可以退出全屏模式 - 但无法显示我在全屏情况下隐藏的 TextView。

要在全屏模式下隐藏 textView，我使用以下代码：

@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider,
        YouTubePlayer player, boolean wasRestored) {
    if (!wasRestored) {
        showPlayer();
        videoPlayer = player;
        videoPlayer.setOnFullscreenListener(new OnFullscreenListener() {

            @Override
            public void onFullscreen(boolean _isFullScreen) {
                fullScreen = _isFullScreen;
                textView.setVisibility(View.GONE); // hiding
            }
        });
        videoPlayer.loadVideo(actualVideo.getVideoId());
    }
}

要显示 textView，当我退出全屏模式时使用：

@Override
public void onBackPressed() {
    if (fullScreen){
        videoPlayer.setFullscreen(false);
        textView.setVisibility(View.VISIBLE); // showing

    } else{
        super.onBackPressed();
    }
}

我不知道为什么？但是，当我点击后退按钮（我的意思是退出全屏模式）时，我的 textView 没有处于可见状态。

_里面是全屏public void onFullscreen(boolean _isFullScreen)是全屏状态，如果为 true 则表示播放器已进入全屏模式，如果为 false 则表示播放器从全屏模式切换回来，并且当您进入全屏模式并进入时会调用此侦听器从全屏模式返回，分别具有 true 和 false 值。您应该修改如下代码

videoPlayer.setOnFullscreenListener(new OnFullscreenListener() {

        @Override
        public void onFullscreen(boolean _isFullScreen) {
            fullScreen = _isFullScreen;
            if(_isFullScreen){
            textView.setVisibility(View.GONE); // hide text as player switched to full screen mode
            } else {
            textView.setVisibility(View.VISIBLE); // show text as player switched back from full screen mode, changing visibility here instead of onBackPressed have advantage that even if user switches back from full screen mode using control button on player instead of press back button the text will still come to visible
            }
        }
    });

如果按下后退按钮时播放器处于全屏模式，则 onBackPressed 侦听器将仅用于将播放器从全屏模式切换回；

@Override
public void onBackPressed() {
if (fullScreen){
    videoPlayer.setFullscreen(false);

} else{
    super.onBackPressed();
}
}
