    public MenuAdapter(Context context, int resource, List<Menu> items) {
        super(context, resource, items);
    }

    @Override    public View getView(int position, View convertView, ViewGroup parent) {

        View v = convertView;

        if (v == null) {
            LayoutInflater vi;
            vi = LayoutInflater.from(getContext());
            v = vi.inflate(R.layout.dong_menu, null);
        }

        Menu mn = getItem(position);

        if (mn != null) {

            // Anh xa + Gan gia tri            TextView tt = (TextView) v.findViewById(R.id.textViewDongmenu);
            tt.setText(mn.Tieude.toString());
            ImageView imageView = (ImageView) v.findViewById(R.id.imageViewDongMenu);
