Answer 1

Use this method:

private void showJSON(String response) {
        list = new ArrayList<>();
        String name = null;
        try {

            JSONArray jsonObject = new JSONArray(response);
            for(int i = 0; i < jsonObject.length(); i++) {
                JSONObject obj = jsonObject.getJSONObject(i);
                //store your variable
                list.add(obj.getString("Name"));
            }
//            JSONArray result = jsonObject.getJSONArray("");
//            JSONObject collegeData = result.getJSONObject(0);
//            list.add(jsonObject.getString(collegeData.getString("Name")));
            Toast.makeText(getActivity(), name, Toast.LENGTH_LONG).show();
            city_list.addAll(list);
            adapter.notifyDataSetChanged();
        } catch (JSONException e) {
            e.printStackTrace();
            // Toast.makeText(getApplicationContext(), response, Toast.LENGTH_LONG).show();
        }

    }

Answer 2

data is an array, not an object:

JSONArray data = jsonObj.getJSONArray("data"); 

Answer 3

Change

JSONObject data = jsonObj.getJSONObject("data"); 

to

JSONArray data = jsonObj.getJSONArray("data");

As value of data is JsonArray not JSONObject.

And to Get individual Ids and Field Names, you should loop through this JSONArray, as follows:

for(int i=0; i<data.length(); i++)
{
     JSONObject obj=data.getJSONObject(i);
     String id = obj.getString("Id"); 
        String value = obj.getString("FieldName"); 
        Log.d("Item name: ", value);
}
