Problems with Json receiving inner value

I have this code which in turn what it does is fetch an id from the database but the first value it fetches is 0 passed 1 second it fetches the correct value I tested with an output text.

Example First id it will fetch: 0

After 1 second, you have id: 33

Click again to get a close id or 34 it will fetch: 33

After 1 second I get id: 34

I used a dialog to try to solve the problem but it did not work.

 JSONObject jsa = null;
    try {
        jsa = new JSONObject(myJSON);


        favId = jsa.getInt("FavoritoId");



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

        dialog.dismiss();
