检索VideoID

Question

我有两个类(YtAdapter和MainActivity)。在YtAdapter中，我有一种获取用户输入(关键字)的方法，并为该关键字搜索Youtube视频。

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder mHolder;
    if(convertView != null){
        mHolder = (ViewHolder)convertView.getTag();
    }else{
        mHolder = new ViewHolder();
        convertView = mLayoutInflater.inflate(R.layout.view_video_item,null);
        mHolder.mVideoThumbnail = (ImageView)convertView.findViewById(R.id.video_thumbnail);
        mHolder.mVideoTitle = (TextView)convertView.findViewById(R.id.video_title);
        convertView.setTag(mHolder);
    }
    //Setting the data
    SearchResult result = mVideoList.get(position);
    mHolder.mVideoTitle.setText(result.getSnippet().getTitle());

    //Loading the image
    Picasso.with(mActivity).load(result.getSnippet().getThumbnails().getMedium().getUrl()).into(mHolder.mVideoThumbnail);

    return  convertView;
}

唯一的问题是，我可以看到视频，但不能播放。在我的MainActivity中，我有一个应该播放视频的OnItemClicked方法，但是，我不知道如何检索列表中的一个视频的VideoID (字符串)。

有人能帮我完成这件事吗？这是OnItemClicked方法的代码：

    @Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    VIDEO_ID = <<<<------ I need to get the VideoID of the video im clicking on in the list of the videos.
    Intent videoIntent = YouTubeStandalonePlayer.createVideoIntent(this,AppConstants.KEY,VIDEO_ID); /*Needed: result.getSnippet().get(videoID());*/
    startActivity(videoIntent);
}

我考虑了YtAdpater中的一个字符串变量，并在MainActivity中使用该变量，现在正在使用该变量。

您可以像这样得到点击的videoId：

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    SearchResult searchResult = (SearchResult) parent.getItemAtPosition(position);
    VIDEO_ID = searchResult.getId().getVideoId();
    Intent videoIntent = YouTubeStandalonePlayer.createVideoIntent(this,AppConstants.KEY,VIDEO_ID); /*Needed: result.getSnippet().get(videoID());*/
    startActivity(videoIntent);
}
