java - 在倒数计时器中启动另一个计时器

Question

我在回合结束时设置暂停时遇到问题。当用户单击按钮时，它开始倒计时计时器，当完成的文本返回到我想要的值时。但我希望在倒计时(计时器)完成时启动另一个 timer2。现在它同时开始计数。每个计时器在屏幕上都有自己的 textView。 这是代码:

    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            long roundtime= Long.parseLong(String.valueOf(msg1))*1000; //User set Time for Round
            long pause= Long.parseLong(String.valueOf(msg2))*1000; //User set Time for Pause
            Counting timer = new Counting(roundtime, 1000); // class CountdownTimer
            Counting2 timer2 = new Counting2(pause, 1000); // class CountdownTimer

            timer.start(); // I want to start with this timer first
            timer2.start(); // And when timer is finished start with this in own textView
        }

使用CountDownTimer .这正是您所需要的。只需启动一个计时器，然后在该计时器的 onFinish() 方法上启动新计时器。像这样的东西:

CountDownTimer timer1 = new CountDownTimer(30000, 1000) {

 public void onTick(long millisUntilFinished) {
//do whatever you need here, this gets called every 1000 milliseconds (the 2nd parameter
of the constructor, the first is total time in ms
 }

 public void onFinish() {
    CountDownTimer timer2 = new CountDownTimer(5000, 1000) {
        //same logic
        };
        timer2.start();
    }
};

timer1.start();
