YouTube播放器在更改为全屏模式时停止

Question

目前，我正在使用youtube api在我的应用程序上显示youtube视频，它工作得很好，但是每当我更改为全屏模式时，视频就会停止，我需要按播放按钮重新启动它。

这听起来可能是一个不重要的问题，但它对于我的应用程序的目的非常重要，所以我真的很感激任何解决方案。

这是我的代码：

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_youtube_player);
final int flags = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;

getWindow().getDecorView().setSystemUiVisibility(flags);

final View decorView = getWindow().getDecorView();
decorView
.setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener() {
@Override
public void onSystemUiVisibilityChange(int visibility) {
if ((visibility & View.SYSTEM_UI_FLAG_FULLSCREEN) == 0) {
decorView.setSystemUiVisibility(flags);
}
}
});
videoID = getIntent().getStringExtra("video_id");
youTubePlayerView = findViewById(R.id.youtube_player_view);
initializeYoutubePlayer();
String [] temp = getIntent().getStringArrayExtra("playlist_order");
if(temp != null)
order = Arrays.copyOf(temp, temp.length);
else {
ImageView nextTrackButton = findViewById(R.id.nextTrackButton);
ImageView lastTrackButton = findViewById(R.id.lastTrackButton);
nextTrackButton.setVisibility(View.GONE);
lastTrackButton.setVisibility(View.GONE);
}

}
/**
* initialize the youtube player
*/
private void initializeYoutubePlayer() {
youTubePlayerView.initialize(Constants.getKey(), new YouTubePlayer.OnInitializedListener() {
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer,
boolean wasRestored) {

if (!wasRestored) {
youTubePlayer.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT);

youTubePlayer.loadVideo(videoID);

youTubePlayer.play();
youTubePlayer.setShowFullscreenButton(true);
myYouTubePlayer = youTubePlayer;
myYouTubePlayer.setPlayerStateChangeListener(new YouTubePlayer.PlayerStateChangeListener() {
@Override
public void onLoading() {
}
@Override
public void onLoaded(String s) {
}
@Override
public void onAdStarted() {
}
@Override
public void onVideoStarted() {
}
@Override
public void onVideoEnded() {
int nextI = 0;
for (int i = 0; i < order.length; i++) {
if (order[i].equals(videoID)) {
nextI = i + 1;
break;
}
}
if (nextI >= order.length) {
nextI = 0;
}
videoID = order[nextI];
myYouTubePlayer.loadVideo(videoID);
}
@Override
public void onError(YouTubePlayer.ErrorReason errorReason) {
}
});
}
}
@Override
public void onInitializationFailure(YouTubePlayer.Provider arg0, YouTubeInitializationResult arg1) {
//print or show error if initialization failed
Log.e(TAG, "Youtube Player View initialization failed");
}
});
}
@SuppressLint("NewApi")
@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}

将此行添加到清单文件

<activity android:name=".MainActivity"

</activity>

Answer 2

Youtube API Android有一个YouTubePlayer.OnFullscreenListener。我认为您可以使用它并使视频在全屏时继续play()。
