如何停止CountDownTimer？

Question

我应该在哪里编辑这段代码，我可以阻止CountDown？

如何在开始下一个新的CountDown之前删除旧的？

public void MyCounter1(){ 
 
     new CountDownTimer(60000, 1000) { 
 
      public void onTick(long millisUntilFinished) { 
 
       txt_timer.setText("Left time : " + millisUntilFinished/1000);       
 
      } 
 
      public void onFinish() { 
 
       txt_timer.setText("done"); 
 
      } 
 
     }.start(); 
 

 
    }

这里是代码：

CountDownTimer timer= null; 
      public void MyCounter1(){ 
       timer =new CountDownTimer(60000, 1000) { 
        public void onTick(long millisUntilFinished) { 
         txt_timer.setText("Left time : " + millisUntilFinished/1000); 
        } 
        public void onFinish() { 
         txt_timer.setText("done"); 
        } 
       }; 
       timer.start(); 

      } 

// To stop & start new timer check not null of timer instance first then cancel existing timer & start new one 
      if(timer != null){ 
       timer.cancel(); 
       MyCounter1(); 
      } 

此外，如果你想取消一审并开始新的一个，你可以添加上述onFinish方法线，将被调用时，计时器完成他的时间。 检查此：

CountDownTimer timer= null; 
     public void MyCounter1(){ 
          timer =new CountDownTimer(60000, 1000) { 
           public void onTick(long millisUntilFinished) { 
            txt_timer.setText("Left time : " + millisUntilFinished/1000); 
           } 
           public void onFinish() { 
            txt_timer.setText("done"); 
            if(timer != null){ 
             timer.cancel(); 
             MyCounter1(); 
            } 
           } 
          }; 
          timer.start(); 

         }

我做了这2行。我工作在罚款时：

public void MyCounter1(){ 
     CountDownTimer countDownTimer = new CountDownTimer(60000, 1000) { 
      public void onTick(long millisUntilFinished) { 
       if(my_condition=1){ //1- just make my_condition<>1 to stop the counter 
       txt_timer.setText("Left time : " + millisUntilFinished/1000); }      
      } 
      public void onFinish() { 
       countDownTimer.cacel(); // 2- delete old one 
       txt_timer.setText("done"); 
      } 
     }.start(); 

    } 

Answer 3

private int time = 10; //example 10 min.  

CountDownTimer(60000 * time, 1000) 

@Override 
      public void onFinish() { 
       txt_timer.setText("done"); 
       cancel(); 
       time = 0;
