我正在制作一个在 android 中实现画中画功能的应用程序。

当您单击图像时，使用画中画功能打开一个新活动。

如果我在不播放视频的情况下激活该功能，则该功能正确完成，但是在播放视频时激活画中画功能时，当输入画中画时，视频停止播放。

Activity实现画中画功能：

public class VideoActivity extends YouTubeBaseActivity {

@BindView(R.id.movie_chat)
VideoYoutubeView movieChat;
private final PictureInPictureParams.Builder mPictureInPictureParamsBuilder =
        new PictureInPictureParams.Builder();
private VideoYoutubeView.OnPipListener onPipListener = (this::setUpPip);

public static Intent getCallIntent(Context context, String messageConversation) {
    Intent intent = new Intent(context, VideoActivity.class);
    return intent;
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_video);
    ButterKnife.bind(this);
    this.setUpView();
}

private void setUpView() {
    this.movieChat.initialize("", "JRfuAukYTKg");
    this.movieChat.setOnPipListener(onPipListener);
}

public void setUpPip() {
    if (movieChat == null)
        return;
    this.movieChat.hideControls();
    //Rational aspectRatio = new Rational(movieChat.getWidth(), movieChat.getHeight());
    Rational aspectRatio = new Rational(20, 10);
    mPictureInPictureParamsBuilder.setAspectRatio(aspectRatio).build();
    enterPictureInPictureMode(mPictureInPictureParamsBuilder.build());
}

@Override
public void onPictureInPictureModeChanged(boolean isInPictureInPictureMode, Configuration newConfig) {
    super.onPictureInPictureModeChanged(isInPictureInPictureMode, newConfig);
    if (!isInPictureInPictureMode) {
        // Show the video controls if the video is not playing
        if (movieChat != null /*&& !movieChat.isPlaying()*/) {
            movieChat.showControls();
        }
    }
}

}

有人可以帮助我使用 YoutubeAndroidPlayerApi 库实现此功能吗？

我认为您还必须在您的活动中覆盖 onPause() -

@Override
public void onPause() {
// If called while in PIP mode, do not pause playback
  if (isInPictureInPictureMode()) {
     // Continue playback
     ...
  } else {
     // Use existing playback logic for paused Activity behavior.
     ...
  }
}

画中画参考Android文档
