{"msg":[{"msg":[{"message":"hi","sender":"C"},{"message":"sd","sender":"A"},
{"message":"herold","sender":"C"},{"message":"s","sender":"A"},
{"message":"tu","sender":"A"},{"message":"xx","sender":"A"},{"message":"re","sender":"A"},

使用以下方法获取您的回复：

public static String getWebserviceResponse(String p_url) {
    String m_response = null;
    HttpClient client = new DefaultHttpClient();
    HttpGet httpget = new HttpGet(p_url);
    HttpResponse response;
    System.err.println("Request URL---------->"+ p_url);
    try {
        response = client.execute(httpget);
        if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
            InputStream in = response.getEntity().getContent();
            StringBuilder sb = new StringBuilder();
            String line = "";
            BufferedReader bf = new BufferedReader(
                    new InputStreamReader(in));
            while ((line = bf.readLine()) != null) {
                sb.append(line);
            }
            m_response = sb.toString();

        }
    } catch (ClientProtocolException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    } catch (IOException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
    return m_response;
}

解析您的回复如下：

 String response=getWebserviceResponse("your request Url");
    JSONObject jo = new JSONObject(response);

              JSONArray resultarr = jo.getJSONArray("msg");
        for (int i = 0; i < resultarr.length(); i++) 
                  {

                      JSONObject jObjresult = resultarr.getJSONObject(i);
                         String index = jObjresult .getString("index");
                         String userId=jObjresult .getString("uid"));
                     JSONArray jObj = jObjresult.getJSONArray("msg");
                        for (int j = 0; j < jObj.length(); j++) 
                        {
                  //Get the messages only from the Sender C.
                           String sender=jObj.getString("sender");
                            if(sender.equalsIgnoreCase("C")
                              { 
                                  String message = jObj.getString("message");
                               }
                       }
          }
