簡單使用Countdown計時器：

new CountDownTimer(30000, 1000) { 

     public void onTick(long millisUntilFinished) { 

       // Here whatever you want to process in the mean time. 
      mTextField.setText("seconds remaining: " + millisUntilFinished/1000); 

     } 

     public void onFinish() { 

      // Here you can set your button to off state. 

     } 
     }.start();
