        r.setPost(false);

        InfiniteProgress prog = new InfiniteProgress();

        Dialog dlg = prog.showInifiniteBlocking();

Hi,

Your response is in json array. So you need to get "root" value first. Check this code. 

JSONParser j = new JSONParser();

                        InputStreamReader isr = new InputStreamReader(input);

                        Map<String, Object> h = j.parseJSON(isr);

                        Log.p(h.toString()); // this will give value including root field

                        ArrayList<Map<String, String>> map = (ArrayList<Map<String, String>>) h

                                .get("root");

                        

                        Log.p(map.toString());

Now you can do whatever you like with the Arraylist map.

Thanks!

how to put the retrive data from json in list...

 m.put("Label1",h.toString());// Label1 is the label name from render

                   for (Object s : o.values()) {

                System.out.println(s);

                a.add(s);//here is my problem, how to display individual value of hashmap

This:

for (String key : m.keySet()) {                

    a.add(m);
    System.out.println("key: " + key );
 }

Is wrong if you just want the values... You are adding the entire hashmap to the ArrayList.

Use:

for (String key : m.keySet()) {                
    a.add(m.getValue());
}
