    Handler timeHandler = new Handler();    Runnable updateTimeThread = new Runnable() {        public void run() {            // TODO Auto-generated method stub            SimpleDateFormat df = new SimpleDateFormat("HH:mm:ss");            String date = df.format(new java.util.Date());            mTimeTv.setText(date);            timeHandler.postDelayed(updateTimeThread, 1000);        }    };
