我想用OnChronometerTickListener實現計時器

Question

我基本上希望在我的應用程序中有一個秒錶活動，它會在30秒過後振動設備，並在60秒時發出通知提醒。我是新開發的應用程序，所以請不要因爲錯過一個明顯的答案而對我產生影響。

我知道我需要Chronometer.OnChronometerTickListener - 但不知道如何實現？

public void shotClockStart(View v) { 

     Chronometer shotclock = (Chronometer) findViewById(R.id.chrono1); 
     shotclock.start(); 
     long timeElapsed = SystemClock.elapsedRealtime() - shotclock.getBase(); 
     if (timeElapsed >= 30000) { 
      // HERE I WANT A VIBRATION ON THE DEVICE. 
     }else if(timeElapsed>=60000){ 
      //HERE I WANT A NOTIFICATION ALERT 
     } 
    } 

Answer 1

必須設置監聽器上Chronometer

public void shotClockStart(View v) { 
    Chronometer shotclock = (Chronometer) findViewById(R.id.chrono1); 
    shotclock.setOnChronometerTickListener(new Chronometer.OnChronometerTickListener() { 
     @Override 
     public void onChronometerTick(Chronometer chronometer) { 
      long timeElapsed = SystemClock.elapsedRealtime() - chronometer.getBase(); 
      if (timeElapsed >= 30000) { 
       // HERE I WANT A VIBRATION ON THE DEVICE. 
      }else if(timeElapsed>=60000){ 
       //HERE I WANT A NOTIFICATION ALERT 
      } 
     } 
    }); 
    shotclock.setBase(SystemClock.elapsedRealtime()); 
    shotclock.start(); 
}
