            HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
            is = httpURLConnection.getInputStream();
            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
            StringBuilder sb = new StringBuilder();
            while((line = bufferedReader.readLine()) != null)
            {
                sb.append(line + "\n");
            }
            is.close();
            result = sb.toString();
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        try
        {
            JSONArray JA = new JSONArray(result);
            JSONObject json;

            s_name = new String[JA.length()];
            s_gender = new String[JA.length()];

            for(int i = 0; i<JA.length(); i++)
            {
                json        =  JA.getJSONObject(i);
                s_gender[i] =  json.getString("s_gender");
                s_name[i]   =  json.getString("s_name");
            }
            list1.add("All");
            for(int i = 0; i<s_name.length; i++)
            {
                list1.add(s_name[i] + " "+s_gender[i]);
            }



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


    }

To use hashmap with arrayadapter you need list with hashmap type:

List<Object> list = new ArrayList<>();

And pass this list to your adapter:

ArrayAdapter<Object> spinner = new ArrayAdapter<>(Games.this, layout.simple_spinner_dropdown_item, list);

hope this may helps you.
