Question

我有一个倒数计时器，我想在几小时，几分钟和几秒钟内打印。我有以下代码，但我得到的输出没有在几分钟内正确转换我不明白我哪里出错了。

enter code here 
CountDownTimer countDownTimer = new CountDownTimer(millisset3, 1000) 

          {
               TextView  tv = (TextView) context.findViewById(R.id.textView2); 
               public void onFinish() {

                     tv.setText("Time finished!");   }

                     public void onTick(long millisUntilFinished) {

                         tv.setText("Time left for Isha:   " +String.format(" %d hours, %d min, %d sec", 
                                    TimeUnit.MILLISECONDS.toHours(millisUntilFinished),
                                    TimeUnit.MILLISECONDS.toMinutes( millisUntilFinished) - 
                                    TimeUnit.MINUTES.toMinutes(TimeUnit.MILLISECONDS.toHours( millisUntilFinished)),
                                    TimeUnit.MILLISECONDS.toSeconds( millisUntilFinished) - 
                                    TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes( millisUntilFinished)))); 
                                 }

       }.start(); 

        }

Answer 1

试试这个

    private long startTime = 0L;
         private Handler myHandler = new Handler();
         long timeInMillies = 0L;
         long timeSwap = 0L;
         long finalTime = 0L;


        //on button click(timer start)

         startTime = SystemClock.uptimeMillis();
            myHandler.postDelayed(updateTimerMethod, 0);

        //=====

//on button click (timer stop)

 timeSwap += timeInMillies;
    myHandler.removeCallbacks(updateTimerMethod);

//==================


        private Runnable updateTimerMethod = new Runnable() {

          public void run() {
           timeInMillies = SystemClock.uptimeMillis() - startTime;
           finalTime = timeSwap + timeInMillies;

           int seconds = (int) (finalTime / 1000);
           int minutes = seconds / 60;
           seconds = seconds % 60;
           int milliseconds = (int) (finalTime % 1000);
           Log.e("" + minutes + ":"
             + String.format("%02d", seconds) + ":"
             + String.format("%03d", milliseconds));
           myHandler.postDelayed(this, 0);
          }

         };

您可以将毫秒传递给此函数，您将获得格式的字符串。

public static String getFormat(long millis)
    {

        DateFormat outFormat = new SimpleDateFormat("hh:mm:ss");
        outFormat.setTimeZone(TimeZone.getTimeZone("UTC"));

        Date d = new Date(millis);
        String result = outFormat.format(d);

        return result;
    }
