String str ="[{\"Category_Id\":\"C1 \",\"Category_Name\":\"breakfast\"},{\"Category_Id\":\"C2 \",\"Category_Name\":\"appetizers & snacks\"},{\"Category_Id\":\"C3 \",\"Category_Name\":\"sandwiches & more\"},{\"Category_Id\":\"C4 \",\"Category_Name\":\"burgers & wraps\"},{\"Category_Id\":\"C5 \",\"Category_Name\":\"salads\"},{\"Category_Id\":\"C6 \",\"Category_Name\":\"soup\"},{\"Category_Id\":\"C7 \",\"Category_Name\":\"pizza & pasta\"},{\"Category_Id\":\"C8 \",\"Category_Name\":\"kids menu\"},{\"Category_Id\":\"C9 \",\"Category_Name\":\"main dishes\"},{\"Category_Id\":\"C10 \",\"Category_Name\":\"oriental cuisine\"},{\"Category_Id\":\"C11 \",\"Category_Name\":\"desserts\"},{\"Category_Id\":\"C12 \",\"Category_Name\":\"shakes & smoothies\"},{\"Category_Id\":\"C13 \",\"Category_Name\":\"drinks\"},{\"Category_Id\":\"C14\",\"Category_Name\":\"333\"}]";
        JSONArray jarray;
        try{
            jarray = new JSONArray("");
            for(int i = 0; i < jarray.length(); i++)
            {
                String id = jarray.getJSONObject(i).getString("Category_Id");
                String name = jarray.getJSONObject(i).getString("Category_Name");
            }
        }catch(Exception e){}

Answer 3

For this all you need to do is a for loop to go through the Json response. Something like this should do the trick.

    JSONArray jsonArray;
    try{
        jsonArray = new JSONArray(myJsonResponse);
        for(int i = 0; i < jsonArray.length(); i++)
        {

JsonObject object = new JsonObject(jsonArray.getJsonObject(i));
            buttonTextString = object.getString("Category_Name);
        }
    } catch(Exception e) {}

You can parse JSONArray before then parse JSONObject to parse each element on your json data. And final setText for button each element you can parse
