            }.getType());
    mAdapter = new AdapterAppointment(getActivity(), listItemService);
    listView.setAdapter(mAdapter);

Answer 1

You should be able to use Collections.sort(...) passing in a Comparator that will compare 2 AppointmentInfoDto objects.

Collections.sort(listItemService, new Comparator<AppointmentInfoDto>() {

    @Override public int compare(AppointmentInfoDto l, AppointmentInfoDto r) {
        // Compare l.ScheduleOn and r.ScheduleOn
    }

}
