Json_response is

{"NameAllList":[{"Current":{"time":"2012-02-21T08:04:21","Name":"abcd"},
    "Next":{"Name":"data1","StartTime":"2012-02-21T08:06:21"}},{"Current":{"time":"2012-02-21T08:14:21","Name":"defg"},

JSONObject subObj = jsonObj.getJSONObject("Current");
String name_current =subObj.getString("Name");

but i am not able to get the value of “Name”. what mistake i have done. provide the link to do the above parsing.

Answer 1

You are not parsing json properly, so you are not able to fetch value of Name. Please note JSON Annotation [] represent JSONArray, and {} respresent JSONObject, so method to get current item’s name is:

JSONObject jsonObj = new JSONObject(json_response_string);
JSONArray jsonArr=jsonObj.getJSONArray("NameAllList");
String Hora_name_current="";
for(int i=0;i<jsonArr.length();i++)
{
     JSONObject obj=jsonArr.get(i);
     try{
           JSONObject subObj = obj.getJSONObject("Current");
           Hora_name_current =subObj.getString("Name");
           break;
     }catch(JSONException ex)
     {

     }
