parsing json object to android string

Question

I have tried to parse a JSON object by lot of ways but can't figure out how to parse that.

This is my json string:

 {
  "JSONDataResult":

        {"Messages":
                   [{ "Id":"0",
                      "Category":"Sport",
                      "Title":"It's a goal",
                      "Content":"sport content"
                    }]
        }
 }

I tried this:

        JSONArray arr = result.getJSONArray("Messages\\");
        for (int j = 0; i < arr.length(); j++)
        {
            String post_id = arr.getJSONObject(i).getString("post_id");
            Id = result.getString("Id\\");
            Title = result.getString("Title\\");
            Content = result.getString("Content\\");   
        }

Is that a json coming from api or a static string, api wont return '\' in result. — Harin

there must be a lot of answers out there but this is the one i did. guess we have a String coming from server or getting it from android cache where you stored before..

String listdata = "some kind of json data, might be your sample..";
JSONObject jsnobject = new JSONObject(listdata);
System.out.println("jsnobject: " + jsnobject);
return jsnobject.getJSONArray("Messages");

or you already have the reponse as a list structured

JSONArray jsonArray = new JSONArray(response.toString());
for (int i = 0; i < jsonArray.length(); i++) {
       .....
}

First you convert it to a valid json object that a json array. where you want the list starts, Messages etc.. so that you can get each elements id, title .. by getString in you example..

Slash is not required. You simply do this

  JSONArray arr = result.getJSONArray("Messages");
    for (int j = 0; i < arr.length(); j++)
    {
        JsonObject object = arr.getJSONObject(i);
       Strng id = object .optString("Id");
      String Title = object .optString("Title");

    }
