[Solved] Android Countdown timer with double speed

by


You should actually try doing it yourself first, but:

new CountDownTimer(5000, 500) {

    public void onTick(long millisUntilFinished) {
        timerText.setText("Half-seconds remaining: " + millisUntilFinished / 500);
    }

    public void onFinish() {
        timerText.setText("done!");
    }
}.start();

The CountDownTimer has two parameters in its constructor, one for the length of the timer as a whole (called millisInFuture, the first parameter), and one for how often the onTick function is called (which is countDownInterval). Both of these parameters are of the long variable type.

Please see CountDownTimer in the Android API.
