Implementing counter in Android

Question

I have got an application where I need to show counter from 3 to 1 then quickly switch to another activity. Will TimerTask will be suitable for doing this? Can anybody show

Answer 1

Use CountDownTimer as shown below.

Step1: create CountDownTimer class

class MyCount extends CountDownTimer {
        public MyCount(long millisInFuture, long countDownInterval) {
            super(millisInFuture, countDownInterval);
        }

        public void onFinish() {
            dialog.dismiss();
           // Use Intent to Navigate from this activity to another
        }

        @Override
        public void onTick(long millisUntilFinished) {
            // TODO Auto-generated method stub
        }
}

Step2: create an object for that class

MyCount counter = new MyCount(2000, 1000); // set your seconds
counter.start();

Answer 2

I would better use a CountDownTimer.

If you want for example your counter to count 3 seconds:

//new Counter that counts 3000 ms with a tick each 1000 ms
CountDownTimer myCountDown = new CountDownTimer(3000, 1000) {
    public void onTick(long millisUntilFinished) {
        //update the UI with the new count
    }

    public void onFinish() {
        //start the activity
   }
};
//start the countDown
myCountDown.start();
