如何在倒数计时器中更改刻度

Question

I have the following CountDownTimer that helps me to set a button visible every 490 ms 30 seconds long.

Is it possible to say that the first 10 seconds the "tick" should be for example 1000ms, the next 10 seconds 700 ms and the last 10 seconds 490ms ?

new CountDownTimer(30000, 490) {

@Override
public void onTick(long millisUntilFinished) {
    for(int i = 0; i< arr.size(); i++){
        Button aga = arr.get(i);
        if(aga.getVisibility() == View.VISIBLE){
            aga.setVisibility(View.GONE);
        }
    }
    int zufall = (int) (Math.random()*23);
    setNextButton(arr.get(zufall));
}

Timer mTimer; // Global 

public void countDownTimerCaller()
{
     static int count = 0;

     int time;

    switch(count)
    {
    case 0:
        time = 1000;
        break;
    case 1:
        time = 700;
        break;
    case 2:
        time = 490;
        break;

        default:
                mTimer.cancel(); // stop timer
            return;
    }

       new CountDownTimer(10000, time) {

        @Override
        public void onTick(long millisUntilFinished) {
            for(int i = 0; i< arr.size(); i++){
                Button aga = arr.get(i);
                if(aga.getVisibility() == View.VISIBLE){
                    aga.setVisibility(View.GONE);
                }
            }
            int zufall = (int) (Math.random()*23);
            setNextButton(arr.get(zufall));

        }

    }

    count++;
}

mTimer = new Timer().schedule(countDownTimerCaller, 10000); // call from where ever you created CountDownTimer instance

除了按这些间隔启动新计时器来满足新要求外，最好的选择就是找到一个共同的除数并将其设置为间隔，然后使用具有模数的开关在所需的时间动作。

Hope this will helpful.

public void countDown(long time) {
        if (time == 490) {
            return;
        }

        new CountDownTimer(10000, time) {

            public void onTick(long millisUntilFinished) {
                // Do whatever you want
             }

             public void onFinish() {
                 countDown(nextTime); // nextTime can be 700, 100, ... It's up to you. (Your rule). :">
             }

        }.start();

    }
