Android ArrayAdapter and JSONArray

Question

I am new to Android Development.

I purely like to work with JSON Objects and Arrays for my simple application considering the lightness of the JSON Carrier compared

I would advise you to use google GSON instead JSON. It is a library that gives you a create objects from JSON-request, and you don't need to parse JSON everymore. Just create an object which contains all the fields from your JSON request and are named the same, and do with it whatever you want - for example:

Your JSON request
{
    [
        {
            "id": "2663",
            "title":"qwe"

        },
        {
            "id": "1234",
            "title":"asd"
        },
        {
            "id": "5678",
            "title":"zxc"
        }

    ]
}

Your class - item of JSON-Array

 public class MyArrayAdapterItem{
     int id;
     String title;
 }

Somwhere in your code where you downloading data. I didn't know how are you doing it so i'll post my code for example:

mGparser = new JsonParser();
Gson mGson = new Gson();

Url url = "http://your_api.com"
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestProperty("Connection", "close");
conn.connect();
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));

JsonArray request = (JsonArray) mGparser.parse(in.readLine());
in.close();
ArrayList items = mGson.fromJson(request, new TypeToken>() {}.getType());

So that's all, for now just put "items" instead JSON-array in your adapter's constructor
