// try this way i have gave demo code you have modify as per your requirement.

public class MyActivity extends Activity {


    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        try{
            JSONArray jsonArray = new JSONArray();
            JSONObject jsonObject = new JSONObject();
            jsonObject.put("name","Haresh");
            JSONObject jsonObject1 = new JSONObject();
            jsonObject1.put("name","Akash");
            JSONObject jsonObject2 = new JSONObject();
            jsonObject2.put("name","Biraj");
            JSONObject jsonObject3 = new JSONObject();
            jsonObject3.put("name","Salim");
            JSONObject jsonObject4 = new JSONObject();
            jsonObject4.put("name","Saloni");
            jsonArray.put(jsonObject1);
            jsonArray.put(jsonObject);
            jsonArray.put(jsonObject3);
            jsonArray.put(jsonObject2);
            jsonArray.put(jsonObject4);


            ArrayList> list = (ArrayList>)toList(jsonArray);
            Collections.sort(list,new Comparator>() {
                @Override
                public int compare(HashMap stringStringHashMap, HashMap stringStringHashMap2) {
                    return stringStringHashMap.get("name").compareTo(stringStringHashMap2.get("name"));
                }
            });
            for (HashMap row : list){
                System.out.println("Row :"+row.get("name"));
            }

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


    }

    private Object fromJson(Object json) throws JSONException {
        if (json == JSONObject.NULL) {
            return null;
        } else if (json instanceof JSONObject) {
            return jsonToMap((JSONObject) json);
        } else if (json instanceof JSONArray) {
            return toList((JSONArray) json);
        } else {
            return json;
        }
    }

    public Map jsonToMap(JSONObject object) throws JSONException {
        Map map = new HashMap();
        Iterator keys = object.keys();
        while (keys.hasNext()) {
            String key = (String) keys.next();
            map.put(key, fromJson(object.get(key)).toString());
        }
        return map;
    }

    @SuppressWarnings({ "rawtypes", "unchecked" })
    private List toList(JSONArray array) throws JSONException {
        List list = new ArrayList();
        int size = array.length();
        for (int i = 0; i < size; i++) {
            list.add(fromJson(array.get(i)));
        }
        return list;
    }
