Countdown Timer keeps starting over on button press

Okay, so I have a countdown timer, and my app requires the user to tap a button numerous times, however the timer starts ON that button tap. My problem is:

I have a 10 second countdown timer that starts at the press of the button, but instead of just continuing down to 0, it restarts at 10 everytime the user taps the button. How do I make it so when the user taps it the first time, it keeps counting down?

My code:

private Button tapBtn;
TextView cm;

tapBtn = (Button) findViewById(R.id.Tap);
cm = (TextView) findViewById(R.id.Timer);

final CountDownTimer aCounter = new CountDownTimer(10000, 1000) {

         public void onTick(long millisUntilFinished) {
            cm.setText("Time Left: " + millisUntilFinished / 1000);
         }

         public void onFinish() {
             cm.setText("Time's Up!");
         }
      };
      aCounter.cancel();

tapBtn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            scr = scr - 1;
            TextView Score = (TextView) findViewById(R.id.Score);
            Score.setText(String.valueOf(scr));
            aCounter.start();
        }
    });
}

Are you trying to make it so that if the user has already started the timer, subsequent button presses don't restart it from the first tap? If so, all you should have to do is put an if statement in your onclick that checks to see if the timer is still counting down, i.e. check and see if the current time is greater than 0 on the counter.

Edit: here's code

final CountDownTimer aCounter = new CountDownTimer(10000, 1000) {

         private long timeLeft;

         public long getTimeLeft() {
            return timeLeft;
         }

         public void onTick(long millisUntilFinished) {
            timeLeft = millisUntilFinished / 1000;

            cm.setText("Time Left: " + timeLeft);

         }

         public void onFinish() {
             cm.setText("Time's Up!");
         }
      };
      aCounter.cancel();

tapBtn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            if (aCounter.getTimeLeft() == 0) {
               scr = scr - 1;
               TextView Score = (TextView) findViewById(R.id.Score);
               Score.setText(String.valueOf(scr));
               aCounter.start();
            }
        }
    });
}

one way to do it is to create a flag that gets set on the first tap and have the onclick event flip the flag on the first click, and put the timer start inside of an if statement that only occurs if the flag hasn't been set.
