YouTube API未按预期播放视频

Question

我正在尝试使用Youtube API为Android构建一个非常简单的视频播放器。到目前为止，我有一个视频（可以点击播放）和下面的两个缩略图——我的问题是：我需要弄清楚如何（正确地）为每个缩略图分配不同的视频——然后播放它们。

我已经尝试分配缩略图，所以使用：

 public static final String VIDEO1_ID = "HNtBphqE_LA";
 public static final String VIDEO2_ID = "YWteQj_q3Ro";
 public static final String VIDEO3_ID = "Ak--L4bYly0"; 

但出于某种原因，我为youTubeThumbnailLoader1和YouTubethumbnailLoader 2显示了正确的缩略图并播放了视频。

有什么建议吗？我只需要调整/修改下面的代码，就可以显示独特的视频/缩略图（而不是像现在这样重复多次）并播放它们。

代码：

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.home);
        youTubePlayerView = (YouTubePlayerView)findViewById(R.id.youtubeplayerview);
        youTubePlayerView.initialize(API_KEY, this);
        youTubeThumbnailView1 = (YouTubeThumbnailView)findViewById(R.id.youtubethumbnailview1);
        youTubeThumbnailView1.initialize(API_KEY, this);
        youTubeThumbnailView2 = (YouTubeThumbnailView)findViewById(R.id.youtubethumbnailview2);
        youTubeThumbnailView2.initialize(API_KEY, this);

        youTubeThumbnailView1.setOnClickListener(new OnClickListener(){
   @Override
   public void onClick(View arg0) {
    if(youTubePlayer != null){
     youTubePlayer.play();
    }
   }});

    youTubeThumbnailView2.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View arg0) {
if(youTubePlayer != null){
 youTubePlayer.play();
}
}});
}
 @Override
 public void onInitializationFailure(Provider provider,
   YouTubeInitializationResult result) {
 }
 @Override
 public void onInitializationSuccess(Provider provider, YouTubePlayer player,
   boolean wasRestored) {
  youTubePlayer = player;
  if (!wasRestored) {
        player.cueVideo(VIDEO_ID);
      }
 }
 @Override
 public void onInitializationFailure(YouTubeThumbnailView thumbnailView, 
   YouTubeInitializationResult error) {

 }
 @Override
 public void onInitializationSuccess(YouTubeThumbnailView thumbnailView, 
   YouTubeThumbnailLoader thumbnailLoader) {

  youTubeThumbnailLoader1 = thumbnailLoader;
  thumbnailLoader.setOnThumbnailLoadedListener(new ThumbnailLoadedListener());
  youTubeThumbnailLoader1.setVideo(VIDEO1_ID);
  youTubeThumbnailLoader2 = thumbnailLoader;
  thumbnailLoader.setOnThumbnailLoadedListener(new ThumbnailLoadedListener());
  youTubeThumbnailLoader2.setVideo(VIDEO2_ID);

 }
 private final class ThumbnailLoadedListener implements
    YouTubeThumbnailLoader.OnThumbnailLoadedListener {
  @Override
  public void onThumbnailError(YouTubeThumbnailView arg0, ErrorReason arg1) {
  }
  @Override
  public void onThumbnailLoaded(YouTubeThumbnailView arg0, String arg1) {

  }
 }
}

p.S.

我认为这可能与我使用youTubeThumbnailView1和youTubeThumbnailView2创建多个缩略图有关，但我觉得这可能不是正确的方法。

您没有为缩略图设置正确的视频。每个拇指钉内部没有区别查看clickListener！

在onCreate 中尝试这样的操作

public void onCreate(Bundle icicle){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.home);
    youTubePlayerView = (YouTubePlayerView)findViewById(R.id.youtubeplayerview);
    youTubePlayerView.initialize(API_KEY, this);
    youTubeThumbnailView1 = (YouTubeThumbnailView)findViewById(R.id.youtubethumbnailview1);
    youTubeThumbnailView1.initialize(API_KEY, this);
    youTubeThumbnailView2 = (YouTubeThumbnailView)findViewById(R.id.youtubethumbnailview2);
    youTubeThumbnailView2.initialize(API_KEY, this);
    youTubeThumbnailView1.setOnClickListener(new OnClickListener(){
        if(youTubePlayer != null){
            youTubePlayer.loadVideo(VIDEO1_ID)
            youTubePlayer.play();
        }
    });
    youTubeThumbnailView2.setOnClickListener(new OnClickListener(){
        if(youTubePlayer != null){
            youTubePlayer.loadVideo(VIDEO2_ID)
            youTubePlayer.play();
        }
    });
}

注意：我在你的代码中看到了很多乱七八糟的东西。

 @Override
 public void onInitializationSuccess(YouTubeThumbnailView thumbnailView, 
   YouTubeThumbnailLoader thumbnailLoader) {
    youTubeThumbnailLoader1 = thumbnailLoader;
    thumbnailLoader.setOnThumbnailLoadedListener(new ThumbnailLoadedListener());
    youTubeThumbnailLoader1.setVideo(VIDEO1_ID);
    youTubeThumbnailLoader2 = thumbnailLoader;
    thumbnailLoader.setOnThumbnailLoadedListener(new ThumbnailLoadedListener());
    youTubeThumbnailLoader2.setVideo(VIDEO2_ID);
 }

这部分表明您对编程缺乏基本的理解。你可以简单地写：

 @Override
 public void onInitializationSuccess(YouTubeThumbnailView thumbnailView, 
   YouTubeThumbnailLoader thumbnailLoader) {
    thumbnailLoader.setOnThumbnailLoadedListener(new ThumbnailLoadedListener());
    thumbnailLoader.setVideo(VIDEO1_ID);
    thumbnailLoader.setVideo(VIDEO2_ID);
 }

这显然不是您想要的。我想你必须在onCreate中创建不同的监听器。不要在thumbnailViews的initialze方法中传递this，并对clickListener进行与我显示的相同的切换。

也试着确定你的问题，只发布相关的东西。
