Android: simple time counter

Question

I have a simple program with one TextView and two Buttons: Button1 and Button2.

Clicking on Button 1 will start a counter, increasing by 1 every 1 second and show res

Answer 1

This way it is much simpler. It is a feature made available on the android developer site. Link

public void initCountDownTimer(int time) {
    new CountDownTimer(30000, 1000) {

        public void onTick(long millisUntilFinished) {
            textView.setText("seconds remaining: " + millisUntilFinished / 1000);
        }

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