CountDownTimer不能正確顯示時間

我正在爲Android開發。我正在使用倒數計時器來顯示某個日期的倒計時。在這篇文章的時候，它應該顯示接近18dys 12hrs 30min 55s的東西。但我得到49dys 19hrs 28min 31s。我相信我的轉換到可讀的日期是正確的，但是再次，我沒有這個計時器的經驗。我的研究正在圈選我。請看看我的代碼，發現我可能有的任何錯誤。提前致謝。CountDownTimer不能正確顯示時間

private void startCountdown() { 
    CountDownTimer mCountDownTimer; 
     Calendar cal1 = Calendar.getInstance(); 
     Calendar cal2 = Calendar.getInstance(); 
     cal2.set(Calendar.YEAR, 2013); 
     cal2.set(Calendar.MONTH, 8); 
     cal2.set(Calendar.DAY_OF_MONTH, 23); 
     cal2.set(Calendar.HOUR_OF_DAY, 7); 
     cal2.set(Calendar.MINUTE, 0); 

    long diffInMillis = cal2.getTimeInMillis() - cal1.getTimeInMillis(); 



     tvCount = (TextView) findViewById(R.id.tvCountdown); 

     mCountDownTimer = new CountDownTimer(diffInMillis, 1000) { 


      @Override 
      public void onFinish() { 
       tvCount.setText("VIEW FIGHT CARD"); 

      } 

      @Override 
      public void onTick(long millisUntilFinished) { 

       String days = null, hours = null, minutes = null, seconds = null; 
       long count = millisUntilFinished/DateUtils.DAY_IN_MILLIS; 
       if(millisUntilFinished > DateUtils.DAY_IN_MILLIS) { 

        if(count > 1) 
         days = (count)+("dys "); 
        else 
         days = (count)+("dy "); 

        millisUntilFinished %= DateUtils.DAY_IN_MILLIS; 
       } 
       if(millisUntilFinished > DateUtils.HOUR_IN_MILLIS) { 
        count = millisUntilFinished/DateUtils.HOUR_IN_MILLIS; 
        if(count > 1) 
         hours = (count) + "hrs "; 
        else 
         hours = count + "hr "; 

        millisUntilFinished %= DateUtils.HOUR_IN_MILLIS; 
       } 
       if(millisUntilFinished > DateUtils.MINUTE_IN_MILLIS) { 
        count = millisUntilFinished/DateUtils.MINUTE_IN_MILLIS; 

        minutes = count + "min"; 

        millisUntilFinished %= DateUtils.MINUTE_IN_MILLIS; 
       } 
       if(millisUntilFinished > DateUtils.SECOND_IN_MILLIS) { 
        count = millisUntilFinished/DateUtils.SECOND_IN_MILLIS; 

        seconds = count + "s"; 

        millisUntilFinished %= DateUtils.SECOND_IN_MILLIS; 
       } 



       tvCount.setText(days + hours + minutes +seconds + ""); 
      } 
     }; 
    mCountDownTimer.start(); 
    }

在Java中，一個月不要忘記爲0索引，以便

一月= 0，日= 1，...，月= 7

更安全的使用

cal2.set(Calendar.MONTH, Calendar.AUGUST);

甚至沒有想到這一點。謝謝。不久，我會接受你的回答。任何想法，爲什麼我的小時休息？也許因爲它假設是24小時制？ –

哦，我是個白癡。我的代碼有錯誤。再次感謝 –
