将gdata feed转换为xml - 将Youtube播放列表转换为ANdroid Listview

Question

我正在关注this code以创建自定义列表视图。

它使用an XML file解析对象，并显示在Listview

我不知道我可以使用相同的例子来说明影片的标题和YouTube播放列表的时间。

我已经虽然YouTube API和GDATA，但我不能找出如何让我可以用上面的例子代码

任何帮助球员使用原始XML的链接？

继承人我曾经使用过的一个课程。这将第一个视频作为“主要”视频，显示时间和标题，然后将所有其他视频添加到布局。

public class Videos extends Activity { 
    ImageView mainThumb; 
    TextView mainTitle; 
    TextView mainTime; 
    LinearLayout videos; 
    ArrayList<String> links; 

    /** Called when the activity is first created. */ 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
     setContentView(R.layout.videos); 

     new ParseVideoDataTask().execute(); 
     mainThumb = (ImageView) findViewById(R.id.mainThumb); 
     mainTitle = (TextView) findViewById(R.id.mainTitle); 
     mainTime = (TextView) findViewById(R.id.mainTime); 
     videos = (LinearLayout) findViewById(R.id.videos); 

    } 

    private class ParseVideoDataTask extends AsyncTask<String, String, String> { 
     int count = 0; 

     @Override 
     protected String doInBackground(String... params) { 
      URL jsonURL; 
      URLConnection jc; 
      links = new ArrayList<String>(); 
      try { 
       jsonURL = new URL("http://gdata.youtube.com/feeds/api/playlists/" + 
        YOUR PLAYLIST ID + 
        "?v=2&alt=jsonc"); 
       jc = jsonURL.openConnection(); 
       InputStream is = jc.getInputStream(); 
       String jsonTxt = IOUtils.toString(is); 
       JSONObject jj = new JSONObject(jsonTxt); 
       JSONObject jdata = jj.getJSONObject("data"); 
       JSONArray aitems = jdata.getJSONArray("items"); 
       for (int i=0;i<aitems.length();i++) { 
        JSONObject item = aitems.getJSONObject(i); 
        JSONObject video = item.getJSONObject("video"); 
        String title = video.getString("title"); 
        JSONObject player = video.getJSONObject("player"); 
        String link = player.getString("default"); 
        String length = video.getString("duration"); 
        JSONObject thumbnail = video.getJSONObject("thumbnail"); 
        String thumbnailUrl = thumbnail.getString("hqDefault") 
        String[] deets = new String[4]; 
        deets[0] = title; 
        deets[1] = thumbnailUrl; 
        deets[2] = length; 
        links.add(link); 
        publishProgress(deets); 
       } 
      } catch (MalformedURLException e) { 
       e.printStackTrace(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } catch (JSONException e) { 
       e.printStackTrace(); 
      }  
      return null; 
     }  

     @Override 
     protected void onProgressUpdate(final String... deets) { 
      count++; 
      if (count == 1) { 
       MainActivity.setImageFromUrl(deets[1], mainThumb, Videos.this); 
       mainTitle.setText(deets[0]); 
       mainTime.setText(formatLength(deets[2]));

      } else {

       time.setText(formatLength(deets[2])); 
       video.setPadding(20, 20, 20, 20); 
       videos.addView(video);

    } 

    private CharSequence formatLength(String secs) {

     int hours = secsIn/3600, 
       remainder = secsIn % 3600,
