如何获得视频列表， HTTP：/ /gdata.youtube.com/feeds/api/playlists/EL5BQGc0nPiVI?v=2&alt=json

我已经作出了计划，对此我能够使用这种URL的抓取视频列表：请检查的这个但这次我想在Android中使用播放列表来获取视频（S）的名单像使用的这个 URL，实际的YouTube视频的网址：

下面我使用JSON但现在我不知道什么样的变化，我的codeI需要做的就是用上面的播放列表中的网址视频列表。

  @覆盖
公共无效的run（）{
    尝试 {

        HttpClient的客户端=新DefaultHttpClient（）;

        HttpUriRequest请求=新HTTPGET（http://gdata.youtube.com/feeds/api/playlists/EL5BQGc0nPiVI?v=2&alt=json）;





        //获取响应YouTube上发回
        HTT presponse响应= client.execute（要求）;
        //将这个响应为可读的字符串
    字符串jsonString = StreamUtils.convertToString
            （response.getEntity（）的getContent（））;
        //创建一个我们可以从字符串中使用JSON对象
        JSONObject的JSON =新的JSONObject（jsonString）;



        //获取的搜索结果项目
    JSONArray jsonArray = json.getJSONObject（数据）getJSONArray（项目）。

        //创建一个列表存储在视频
        名单＆LT;视频＆GT;视频=新的ArrayList＆LT;视频＆GT;（）;

        的for（int i = 0; I＆LT; jsonArray.length（）;我++）{
            的JSONObject的JSONObject = jsonArray.getJSONObject（我）;
            //视频的标题
            字符串标题= jsonObject.getString（标题）;

            字符串URL;
            尝试 {
    URL = jsonObject.getJSONObject（玩家）的getString（默认）。
    }赶上（JSONException忽略）{
    URL = jsonObject.getJSONObject（玩家）的getString（默认）。
            }


            字符串thumbUrl = jsonObject.getJSONObject（缩略图）的getString（sqDefault）。


            videos.add（新的视频（标题，URL，thumbUrl））;
        }

        库LIB =新库（用户名，视频）;

        捆绑数据=新包（）;
        data.putSerializable（图书馆，LIB）;

        消息味精= Message.obtain（）;
        msg.setData（数据）;
        replyTo.sendMessage（MSG）;

    }赶上（ClientProtocolException E）{
        Log.e（Feck，E）;
    }赶上（IOException异常E）{
        Log.e（Feck，E）;
    }赶上（JSONException E）{
        Log.e（Feck，E）;
    }
}
 

解决方案

 字符串JKYouTubeActivity.YOUTUBE_INFO_URL=http://gdata.youtube.com/feeds/api/playlists/_ID_?v=2&alt=json

 私人字符串的getURL（字符串ID）抛出IOException异常，JSONException {
        HttpClient的客户端=新DefaultHttpClient（）;
        HTTPGET clientGetMethod =新HTTPGET（JKYou​​TubeActivity.YOUTUBE_INFO_URL.replace（_ ID_，ID））;
        HTT presponse clientResponse = NULL;
        clientResponse = client.execute（clientGetMethod）;
        字符串infoString = _convertStreamToString（clientResponse.getEntity（）的getContent（））;
        字符串urldata =新JSONObject(infoString).getJSONObject("entry").getJSONObject("media$group").getJSONArray("media$content").getJSONObject(0).getString("url");
        返回新JSONObject(infoString).getJSONObject("entry").getJSONObject("media$group").getJSONArray("media$content").getJSONObject(0).getString("url");
    }

    私人字符串_convertStreamToString（InputStream的IS）{
        的BufferedReader读卡器=新的BufferedReader（新InputStreamReader的（是））;
        StringBuilder的S B =新的StringBuilder（）;
        串线= NULL;
        尝试 {
            而（（行= reader.readLine（））！= NULL）
            {
                sB.append（线）.append（\ N）;
            }
        }赶上（IOException异常E）{
            e.printStackTrace（）;
        } 最后 {
            尝试 {
                iS.close（）;
            }赶上（IOException异常E）{
                e.printStackTrace（）;
            }
        }
        返回sB.toString（）;
    }

}
 

获取urldata后，您可以流，或做任何你想做的。同样也可以得到缩略图和标题太

How to get list of videos from http://gdata.youtube.com/feeds/api/playlists/EL5BQGc0nPiVI?v=2&alt=json

I have made a program in which i am able to fetch list of videos by using this kind of URL : please check this but this time I want to get list of video(s) using Playlist in Android like using this URL, actual YouTube videos URL:

Here i am using JSON but now i don't know what are the changes in my code i need to do to get the list of videos using above playlist URL.

  @Override
public void run() {
    try {

        HttpClient client = new DefaultHttpClient();

        HttpUriRequest request = new HttpGet("http://gdata.youtube.com/feeds/api/playlists/EL5BQGc0nPiVI?v=2&alt=json"); 





        // Get the response that YouTube sends back
        HttpResponse response = client.execute(request);
        // Convert this response into a readable string
    String jsonString = StreamUtils.convertToString
            (response.getEntity().getContent());
        // Create a JSON object that we can use from the String
        JSONObject json = new JSONObject(jsonString);



        // Get are search result items
    JSONArray jsonArray = json.getJSONObject("data").getJSONArray("items");

        // Create a list to store are videos in
        List<Video> videos = new ArrayList<Video>();

        for (int i = 0; i < jsonArray.length(); i++) {
            JSONObject jsonObject = jsonArray.getJSONObject(i);
            // The title of the video
            String title = jsonObject.getString("title");

            String url;
            try {
    url = jsonObject.getJSONObject("player").getString("default");
    } catch (JSONException ignore) {
    url = jsonObject.getJSONObject("player").getString("default");
            }


            String thumbUrl = jsonObject.getJSONObject("thumbnail").getString("sqDefault");


            videos.add(new Video(title, url, thumbUrl));
        }

        Library lib = new Library(username, videos);

        Bundle data = new Bundle();
        data.putSerializable(LIBRARY, lib);

        Message msg = Message.obtain();
        msg.setData(data);
        replyTo.sendMessage(msg);

    } catch (ClientProtocolException e) {
        Log.e("Feck", e);
    } catch (IOException e) {
        Log.e("Feck", e);
    } catch (JSONException e) {
        Log.e("Feck", e);
    }
}

 String JKYouTubeActivity.YOUTUBE_INFO_URL=http://gdata.youtube.com/feeds/api/playlists/_ID_?v=2&alt=json

 private String getUrl(String id) throws IOException, JSONException {
        HttpClient client = new DefaultHttpClient();
        HttpGet clientGetMethod = new HttpGet(JKYouTubeActivity.YOUTUBE_INFO_URL.replace("_ID_", id));
        HttpResponse clientResponse = null;
        clientResponse = client.execute(clientGetMethod);
        String infoString = _convertStreamToString(clientResponse.getEntity().getContent());
        String urldata=new JSONObject(infoString).getJSONObject("entry").getJSONObject("media$group").getJSONArray("media$content").getJSONObject(0).getString("url");
        return new JSONObject(infoString).getJSONObject("entry").getJSONObject("media$group").getJSONArray("media$content").getJSONObject(0).getString("url");
    }

    private String _convertStreamToString(InputStream iS) {
        BufferedReader reader = new BufferedReader(new InputStreamReader(iS));
        StringBuilder sB = new StringBuilder();
        String line = null;
        try {
            while ((line = reader.readLine()) != null)
            {
                sB.append(line).append("\n");
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                iS.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return sB.toString();
    }

}

After getting the urldata you can streamed it or do whatever you want to. Same as well you can get Thumbnails and title too
