You would normally parse the data this way:

try {
    JSONObject jsonObject = new JSONObject(rawData);
    JSONArray jsonArray = jsonObject.getJSONArray("result");
    for (int i = 0; i < jsonArray.length(); i++) {
        JSONObject mealObject = jsonArray.getJSONObject(i);
        String id = mealObject.getString("id");
        String expendName = mealObject.getString("ExpendName");
        String cost = mealObject.getString("Cost");
        String date = mealObject.getString("Dates");

        //Do whatever you want with the data
     }
 } catch (JSONException e) {
    e.printStackTrace();
 }

Here "rawData" is it the "response" of Json object? – Taufiq Jan 12 '18 at 08:34
It's the JSON data that you posted above. `rawData` is the `String` object storing the above JSON response. – Pulak Jan 12 '18 at 08:54
See the answers [here](https://stackoverflow.com/questions/9605913/how-to-parse-json-in-android) for more information on parsing JSON – Pulak Jan 12 '18 at 08:56
It shows error in this line as I requested json object request `JSONObject jsonObject = new JSONObject(response);` Can you please help!! – Taufiq Jan 12 '18 at 10:38
`final JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener() {@Overridepublic void onResponse(JSONObject response)` – Taufiq Jan 12 '18 at 10:51
Here `response` is a `JSONObject`. You can do `JSONObject jsonObject = response;` in the above code and everything else remain be same. – Pulak Jan 12 '18 at 10:54
It is showing error, Would you check it. `try { JSONObject jsonObject = response; JSONArray jsonArray = jsonObject.getJSONArray("result"); for (int i = 0; i < jsonArray.length(); i++) { JSONObject mealObject = jsonArray.getJSONObject(i); Dataset dataSet = new Dataset(); dataSet.setName(mealObject.getString("ExpendName")); dataSet.setWorth(mealObject.getInt("Cost")); list.add(dataSet); }` – Taufiq Jan 12 '18 at 11:00
Yes, the code should be like this along with the `catch` block – Pulak Jan 12 '18 at 11:03
How do you expect help when you are not clear about the error message you are getting? It's not a site having magicians – Pulak Jan 12 '18 at 11:09
