我嘗試創建一個custome過去的時間,它會啓動計時器,一旦我拿着音量鍵,並假設時間必須停止後,我釋放的鑰匙,但我有問題時,我釋放的關鍵定時器仍在移動。請什麼我失蹤感謝指教停止在Android的更新時間

公共布爾的onkeydown(INT的keyCode,KeyEvent的事件){ 如果((的keyCode == KeyEvent.KEYCODE_VOLUME_DOWN & & shouldCont ==真& & event.getAction()==的KeyEvent .ACTION_DOWN)){ startRecord(); repeat = true; 如果(重複==真& & event.getAction()== KeyEvent.ACTION_DOWN){ t.scheduleAtFixedRate(新的TimerTask(){

  public void run() { 
       runOnUiThread(new Runnable() { 

        public void run() { 
         long timeGoneMillis = System.currentTimeMillis() - startTime; 

         TextView tv = (TextView) findViewById(R.id.timer); 
         tv.setText(""+util.milliSecondsToTimer(timeGoneMillis));       
        } 

       }); 
      } 

     }, 
     //Set how long before to start calling the TimerTask (in milliseconds) 
     0, 
     //Set the amount of time between each execution (in milliseconds) 
     1000);} 
     shouldCont = false; 
    }

,我發現,我們不能真正殺死由定時器實例使用cancel(),所以我只是添加了t.cancel()並且定時器實例將停止。
