Question

The question is: How can I add or remove time from the CountDownTimer during the count down?

For example: The user does something good: +5sec, the user does something wrong: -5sec.

Can someone help me with some code?

Answer 1

Maybe something like this

abstract class MyTimer {

    public MyTimer(long deadline, long interval)
    {
        mDeadline = deadline;
        mInterval = interval; 

        mTimer = new MyCountDownTimer(mDeadline, mInterval);

    }

    public synchronized void start() {

       mTimer.start();

    }

    public abstract void onTick(long time);
    public abstract void onFinish();

    public synchronized void userDidRight() 
    {
        mTimer.cancel();
        mTimer = new MyCountDownTimer(mDeadline, mInterval += 5000);
        mTimer.start();
    }

    public synchronized void userDidWrong() 
    {
        mTimer.cancel();
        mTimer = new MyCountDownTimer(mDeadline, mInterfval -= 5000);
        mTimer.start();
    }


    private class MyCountDownTimer extends CountDownTimer() {

        private abstract void onFinish() {
            MyTimer.this.onFinish();
        }

        private abstract void onTick(long time) {
            MyTimer.this.onTick(time);
        }
    }

    private MyCountDownTimer mTimer;
}
