Parse json before array

Question

I am studying. Please do not kick me ))) I was reading how to parse JSON from array to strings, but my document starts with 2 attributes and only then goes into an array.

"total": 56964,
"last": "2016-05-03 09:12:00",
"quotes": [
    {
        "id": 439124,
        "description": "Xxx: А давай какую-нибудь фирму заведем.<br>Yyy: o.O Зачем?<br>Xxx: Ну, у меня же аллергия. Кошек нельзя :)",
        "time": "2016-05-03 09:12:00",
        "rating": 0
    }

Here's my array "quotes". How i must to handle two items before array?

And last. Array has 50 items. Best way to show this on screen is use ListView with 2 textview for "total" and "last" + textviews for each item in array?

Valid JSON would look something like: { "total": 56964, "last": "2016-05-0309: 12: 00", "quotes": [ { "id": 439124, "description": "Xxx: Адавайкакую-нибудьфирмузаведем.<br>Yyy: o.OЗачем?<br>Xxx: Ну,уменяжеаллергия.Кошекнельзя: )", "time": "2016-05-0309: 12: 00", "rating": 0 } ] } — Junaid

To parse JSON you require valid JSON. You cannot parse a random string as JSON. — Junaid

Try this:

               try {
                    String json = ""; // This should be the JSON from Your API
                    JSONObject jObj = new JSONObject(json);
                    String total = jObj.optString("total");
                    String last = jObj.optString("last");
                    JSONArray jsonArray = jObj.getJSONArray("quotes");

                } catch (JSONException jex) {
                    jex.printStackTrace();
                }

jsonArray now holds the quotes array, use a for loop and extract the nested JSONObjects one by one.

total and last hold the two variables before your quotes array.

As a best practise you can define your JSON nodes as private static Strings just after your class declaration:

private static String TOTAL = "total"

"total" should be an int or a double

Can you support me with displaying infromation? ListView?

You can post that as a separate question, it also depends on your use case - DO you want to persist data? Do you want to use a content provider so that your views refresh automatically when your datasource refreshes. However if you google a simple example for JSON to ListView in Android, I am pretty sure you will find a lot of simple examples from where you can build up. For a starter, check this out.

@Skynet I used your solution in my code here stackoverflow.com/questions/37092206/… But i did something wrong. Please impart a second to review.

You could use gson to parse it to an object and then access the properties via that object. So that the "total" would be an int or a double. And the "last" would be a string. Then your quotes would be a List where object would have the properties of each json object item in the jsonarray.
