Question

我在圆桌时间结束时遇到暂停问题。当用户点击按钮时，它开始倒计时，当完成的文本返回到我想要的值时。但是当倒计时（计时器）结束时，我希望启动另一个timer2。现在它开始计数了。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
        }

Answer 1

使用CountDownTimer。这是你所需要的。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。类似的东西：

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();

Answer 2

如果我已正确理解您的问题，您需要这样的东西。一旦您的活动开始，必须在＆x; xx＆＃39;之后发生一些事情。秒。然后必须暂停一下＆＃39; yy＆＃39;秒，然后同样的事情必须＆＃39; xx＆＃39;秒。正确？

您可以使用Handler.postDelayed()

static boolean pause = false;

onCreate(){
    if (pause) {
        delay = xx + yy;
else
       delay = xx;


Handler.postdelay(new ... , delayTime);

然后很明显，在PostDelay的内部类中生成pause = true

在倒计时器中启动另一个计时器
