Question

My goal is simple:

In my xml file,I have a textview called: textView2.

What I need is a countdown,that countsdown from 15 to 0,and every time a second passes

Answer 1

Try this:----

TextView textic = (TextView) findViewById(R.id.textView2);

CountDownTimer Count = new CountDownTimer(30000, 1000) {
    public void onTick(long millisUntilFinished) {
        textic.setText("Seconds remaining: " + millisUntilFinished / 1000);
    }

    public void onFinish() {
        textic.setText("Finished");
    }
};

Count.start();
