由于某种原因，我所有的缩略图看起来都一样。我不确定我到底做错了什么，但我相信你们中的一个人可以发现问题（这是我第一次使用 Youtube API）

有什么建议么？

附言

我认为这可能与我使用 youTubeThumbnailView1 和 youTubeThumbnailView2 创建多个缩略图的事实有关——但是我觉得这可能不是正确的做法。

问题是这个功能：

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

    youTubeThumbnailLoader = thumbnailLoader;
    thumbnailLoader
    .setOnThumbnailLoadedListener(new ThumbnailLoadedListener());

    //You are always loading the thumbnail of VIDEO_ID
    youTubeThumbnailLoader.setVideo(VIDEO_ID);

}

您总是在加载 VIDEO_ID 的缩略图。您应该检查哪个视图已初始化。尝试这个：

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

    youTubeThumbnailLoader = thumbnailLoader;
    thumbnailLoader
    .setOnThumbnailLoadedListener(new ThumbnailLoadedListener());

    if (thumnailView.equals(youTubeThumbnailView1)
       youTubeThumbnailLoader.setVideo(VIDEO1_ID);
    else
       youTubeThumbnailLoader.setVideo(VIDEO2_ID);

}

看来您正在调用youTubePlayer.cueVideo(VIDEO1_ID);youTubeThumbnailView1 和 youTubeThumbnailView2。
