Question

我在我的应用程序中使用CountDownTimer，它显示错误的时间。这就是我的尝试。

long miliSecsDate = milliseconds ("2017-11-18 12:35");

将日期和时间转换为毫秒

public long milliseconds(String date)
            {
                SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm");
                try
                {
                    Date mDate = sdf.parse(date);
                    long timeInMilliseconds = mDate.getTime();
                    return timeInMilliseconds;
                }
                catch (ParseException e)
                {
                    e.printStackTrace();
                }
                return 0;
            }

倒数计时器

public void showCountdown(long miliSecsDate){
        new CountDownTimer(miliSecsDate, 1000) {
            public void onTick(long millisUntilFinished) {
                long seconds= TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished);

                int minutes = (int)(seconds % 3600) / 60;
                int hours = (int)seconds / 3600;
                seconds = seconds % 60;
                Log.d("time",""+hours+" : "+minutes+" : "+seconds);
          }
            public void onFinish() {
                txtRemainingTime.setText("done!");
            }

        }.start();
    }

我的Log cat如下所示

D/time: 419719 : 3 : 43

尝试使用：

    String myDate = "2017-11-18 12:35";
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm");
    Date date = sdf.parse(myDate);
    long millis = date.getTime();

    long seconds = millis/1000;
    long sec = seconds % 60;
    long min = (seconds / 60) % 60;
    long hrs = (seconds / (60 * 60)) % 24;


    Log.d("time",""+hrs+" : "+min+" : "+sec);
