Try to use UpdateDisplay function like below:

private void updateDisplay() {
    Timer timer = new Timer();
    timer.schedule(new TimerTask() {

        @Override
        public void run() {
            Calendar c = Calendar.getInstance();
            mYear = c.get(Calendar.YEAR);
            mMonth = c.get(Calendar.MONTH);
            mDay = c.get(Calendar.DAY_OF_MONTH);
            mHour = c.get(Calendar.HOUR_OF_DAY);
            mMinute = c.get(Calendar.MINUTE);
            mSecond = c.get(Calendar.SECOND);

            cDateDisplay.setText(new StringBuilder()
                // Month is 0 based so add 1
                .append(mDay).append("/")
                .append(mMonth + 1).append("/")
                .append(mYear).append(" "));

            cTimeDisplay.setText(
                new StringBuilder()
                    .append(pad(mHour)).append(":")
                    .append(pad(mMinute)).append(":").append(pad(mSecond))
            );
        }

    },0,1000);//Update text every second
}

Finally, you must to call updateDisplay() in onCreate() function.
I hope this code would help you finish what you want !
