java - 如何将YouTube播放列表解析为ArrayList

Question

我是parsing简单 JSON ，如下所示:

if (status == 200) {
    HttpEntity entity = response.getEntity();
    String data = EntityUtils.toString(entity);                 

    JSONObject jsono = new JSONObject(data);
    JSONArray jarray = jsono.getJSONArray("actors");

    for (int i = 0; i < jarray.length(); i++) {
        JSONObject object = jarray.getJSONObject(i);

        Actors actor = new Actors();

        actor.setName(object.getString("name"));                        
        actor.setImage(object.getString("image"));

        actorsList.add(actor);
    }
    return true;
}

这是使用 AsyncTask 执行的 JSON链接:

 new JSONAsyncTask().execute("http://microblogging.wingnity.com/JSONParsingTutorial/jsonActors");

但是现在我必须 parse Youtube JSON Playlist:

 http://gdata.youtube.com/feeds/api/playlists/PLWz5rJ2EKKc9ofd2f-_-xmUi07wIGZa1c?v=2&alt=jsonc

我需要获取一些东西，例如:每个 ，每个视频的 Title， Thumbnail和 Link
Pojo:

public class Actors {

    private String name;    
    private String image;

    public Actors() {

    }

    public Actors(String name, String image) {
        super();
        this.name = name;
        this.image = image;
    }


    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getImage() {
        return image;
    }

    public void setImage(String image) {
        this.image = image;
    }

}

您会收到这样的响应(使用ChannelId(查询参数)的 IMPT PlayingList响应)

{
 "kind": "youtube#playlistListResponse",
 "etag": "\"Y3xTLFF3RLtHXX85JBgzzgp2Enw/O8-3nTBpPVrsEjyg6BXeSSO2pU0\"",
 "pageInfo": {
  "totalResults": 3,
  "resultsPerPage": 5
 },
 "items": [
  {

   "kind": "youtube#playlist",
   "etag": "\"Y3xTLFF3RLtHXX85JBgzzgp2Enw/06IYq1oWiveiXSEbF8J6Ucf9LYs\"",
   "id": "PLFE56E5CE58D71A55",
   "snippet": {
    "publishedAt": "2012-04-05T17:01:18.000Z",
    "channelId": "UCjXfkj5iapKHJrhYfAF9ZGg",
    "title": "T&T Elite Canada 2012, April 4, 2012",
    "description": "",
    "thumbnails": {
     "default": {
      "url": "https://i.ytimg.com/vi/default.jpg"
     },
     "medium": {
      "url": "https://i.ytimg.com/vi/default.jpg"
     },
     "high": {
      "url": "https://i.ytimg.com/vi/default.jpg"
     }
    },
    "channelTitle": "AlbertaGymnastics",
    "localized": {
     "title": "T&T Elite Canada 2012, April 4, 2012",
     "description": ""
    }
   }
  }, ... and more items..}

现在为上述json响应创建一个pojo，并从 items数组中读取视频详细信息
