Countdown timer with pause and resume

Question

I want to do countdown timer with pause and restart.Now i am displaying countdown timer By implenting ontick() and onfinish().please help me out.HEre is th code for countdow

Answer 1

I am afraid that it is not possible to pause or stop CountDownTimer and pausing or stopping in onTick has no effect whatsoever user TimerTask instead.

Set up the TimerTask

class UpdateTimeTask extends TimerTask {
   public void run() {
       long millis = System.currentTimeMillis() - startTime;
       int seconds = (int) (millis / 1000);
       int minutes = seconds / 60;
       seconds     = seconds % 60;

       timeLabel.setText(String.format("%d:%02d", minutes, seconds));
   }

}
if(startTime == 0L) {
   startTime = evt.getWhen();
   timer = new Timer();
   timer.schedule(new UpdateTimeTask(), 100, 200);
}

You can add event listener's like this..

private Handler mHandler = new Handler();

...

OnClickListener mStartListener = new OnClickListener() {
   public void onClick(View v) {
       if (mStartTime == 0L) {
            mStartTime = System.currentTimeMillis();
            mHandler.removeCallbacks(mUpdateTimeTask);
            mHandler.postDelayed(mUpdateTimeTask, 100);
       }
   }
};

OnClickListener mStopListener = new OnClickListener() {
   public void onClick(View v) {
       mHandler.removeCallbacks(mUpdateTimeTask);
   }
};
