android按鈕啓動2個定時器

Question

我想在按下一個啓動按鈕時啓動2個倒計時定時器。 當按下啓動，maxTimer設置爲minTimer的價值，他們都倒計數以相同的值。 我該如何分開2？我需要minTimer和maxTimer的倒計時功能。

你需要創建2個CounterClass定時器...

final CounterClass timer = new CounterClass(minTid, 1000); 
    final CounterClass timer2 = new CounterClass(maxTid, 1000); 
     tv_start.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       timer.start(); 
       timer2.start() 
      } 




    }); 
     tv_stop.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       timer.cancel(); 
       timer2.cancel() 

      } 

     }); 
    }
