这是我的代码-

public class FullscreenDemoActivity extends YouTubeFailureRecoveryActivity
        implements View.OnClickListener,

        YouTubePlayer.OnFullscreenListener {
//  private MyPlaybackEventListener myPlaybackEventListener;
    private static final int PORTRAIT_ORIENTATION = Build.VERSION.SDK_INT < 9 ? ActivityInfo.SCREEN_ORIENTATION_PORTRAIT
            : ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT;

    private LinearLayout baseLayout;
    private YouTubePlayerView playerView;
    public YouTubePlayer player;
    private Button fullscreenButton;
    private CompoundButton checkbox;
    private View otherViews;

    private boolean fullscreen;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.fullscreen_demo);
        baseLayout = (LinearLayout) findViewById(R.id.layout);
        playerView = (YouTubePlayerView) findViewById(R.id.player);
        fullscreenButton = (Button) findViewById(R.id.fullscreen_button);
        checkbox = (CompoundButton) findViewById(R.id.landscape_fullscreen_checkbox);
        otherViews = findViewById(R.id.other_views);
        playerView.initialize(DeveloperKey.DEVELOPER_KEY, this);

    }

    @Override
    public void onInitializationSuccess(YouTubePlayer.Provider provider,
            YouTubePlayer player, boolean wasRestored) {
        this.player = player;
        setControlsEnabled();
        // Specify that we want to handle fullscreen behavior ourselves.
        player.addFullscreenControlFlag(YouTubePlayer.FULLSCREEN_FLAG_CUSTOM_LAYOUT);
        player.setOnFullscreenListener(this);
        if (!wasRestored) {
            player.cueVideo("avP5d16wEp0");
        }
        int controlFlags = player.getFullscreenControlFlags();
        setRequestedOrientation(PORTRAIT_ORIENTATION);
        controlFlags |= YouTubePlayer.FULLSCREEN_FLAG_ALWAYS_FULLSCREEN_IN_LANDSCAPE;
        player.setFullscreenControlFlags(controlFlags);
        player.play();


    }

    @Override
    protected YouTubePlayer.Provider getYouTubePlayerProvider() {
        return playerView;
    }

    @Override
    public void onClick(View v) {
        player.setFullscreen(!fullscreen);
    }



    private void doLayout() {
        LinearLayout.LayoutParams playerParams = (LinearLayout.LayoutParams) playerView
                .getLayoutParams();
        if (fullscreen) {
            // When in fullscreen, the visibility of all other views than the
            // player should be set to
            // GONE and the player should be laid out across the whole screen.
            playerParams.width = LayoutParams.MATCH_PARENT;
            playerParams.height = LayoutParams.MATCH_PARENT;

            otherViews.setVisibility(View.GONE);
        } else {
            otherViews.setVisibility(View.VISIBLE);

          }

          @Override

           updateLog("onSeekTo(): " + String.valueOf(arg0));
          }

          @Override
          public void onStopped() {
              player.loadVideo("avP5d16wEp0");

              player.cueVideo("avP5d16wEp0");

推荐答案

我搜索了那个话题，发现没有官方的方式，不会按照此页面在 Google 代码上.

I searched for that topic and I found that there is not an official way and won't be according to this page on Google code.

他们建议你创建一个播放器.

In it they propose that you create a player.

隐藏播放器.

将播放器静音.

使用您的 videoId 和可选偏移量调用 seekTo().

Call seekTo() with your videoId and optional offset.

等待状态更改为正在播放".

Wait for state change to "playing".

按下暂停键.

调用 seekTo(originalOffset, false).

Call seekTo(originalOffset, false).

取消静音播放器.

显示播放器.(或其他).

Show the player. (or whatever).

它可能无法满足您的需要，但也许您可以使用此方法更改实现目标所需的内容.

It maybe doesn't do what you need but maybe you can change what you need to achieve your goal using this method.
