Formatting seconds and minutes

Question

I need to format seconds and minutes from milliseconds. I am using countdownTimer. does anyone have sugestions? I looked at joda time. But all i need is a format so i have 1:05 and not 1:5. thanks

private void walk() {
    new CountDownTimer(15000, 1000) {
        @Override
        public void onFinish() {
            lapCounter++;
            lapNumber.setText("Lap Number: " + lapCounter);
            run();
        }

        @Override
        public void onTick(long millisUntilFinished) {
            text.setText("Time left:" + millisUntilFinished/1000);
        }
    }.start();
}

You could do it using the standard Date formatting classes, but that might be a bit heavy-weight. I would just use the String.format method. For example:

int minutes = time / (60 * 1000);
int seconds = (time / 1000) % 60;
String str = String.format("%d:%02d", minutes, seconds);
