Need help to parse the JSON in android

Question

I need to get the id from this JSON.

{"previous_cursor_str":"0","next_cursor":0,"ids":[494942776,459450174,446965652,413869166,230653243,303016940,301473992,299765702],"previous_cursor":0,"next_cursor_str":"0"}

This json is the response from a url.

I tried the following, to get the id.

JSONObject json = JSONfunctions.getJSONfromURL("url");  
            JSONObject  id = json.getJSONObject("ids");
                Log.v("id....>>",id+"");

got the error.

02-17 22:34:10.995: W/System.err(418): org.json.JSONException: JSONObject["id"] not found.

Answer 1

您的JSON使用的是“ id”而不是“ id”。

Answer 2

Replace:

JSONObject  id = json.getJSONObject("id");

with

JSONArray array = json.getJSONArray("ids");

Then loop through that...

Answer 3

You are getting "ids" JSONArrayObject.

JSONArray  ids = json.getJSONArray("ids");
id = ids.getString(0);

Answer 4

First create Json object, if you are getting response as string use this:

JSONObject obj = new JSONObject(responseString);

Then get ids JSONArray from it as :

JSONArray idArr = obj.getJSONArray("ids");

Now you have list of ids, to get first id use :

idArr.getLong(0)
