درخواست راهنمایی برای رفع باگ روزشمار

اون عبارتی که گفتید فرمت تاریخ هست که باید تعیین کنم:

 ("SimpleDateFormat") SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date futureDate = dateFormat.parse(examTime);
Date currentDate = new Date();

public void countDownStart(final String examTime) {
   handler = new Handler();
   runnable = new Runnable() {
    @SuppressLint("DefaultLocale")
    @Override
    public void run() {
      handler.postDelayed(this, 1000);
      try {
        @SuppressLint("SimpleDateFormat") SimpleDateFormat dateFormat = new SimpleDateFormat(
          "yyyy-MM-dd HH:mm:ss");

        Date futureDate = dateFormat.parse(examTime);
        Date currentDate = new Date();
        if (!currentDate.after(futureDate)) {
          long difference = futureDate.getTime() - currentDate.getTime();

          long months = difference / (30 * 24 * 60 * 60 * 1000);
          difference -= months * (30 * 24 * 60 * 60 * 1000);
          long days = difference / (24 * 60 * 60 * 1000);
          difference -= days * (24 * 60 * 60 * 1000);
          long hours = difference / (60 * 60 * 1000);
          difference -= hours * (60 * 60 * 1000);
          long minutes = difference / (60 * 1000);
          difference -= minutes * (60 * 1000);
          long seconds = difference / 1000;

          txt_month.setText("" + String.format("%02d", months));
          txt_day.setText("" + String.format("%02d", days));
          txt_hour.setText("" + String.format("%02d", hours));
          txt_min.setText("" + String.format("%02d", minutes));
          txt_scd.setText("" + String.format("%02d", seconds));

        }
      } catch (Exception e) {
        e.printStackTrace();
      }
    }
  };
  handler.postDelayed(runnable, 1000);
}

راه حلش رو پیدا کردم.کد رو قرار میدم اگر کسی نیاز داشت استفاده کنه

public void countDownStart(final String examTime) {
  handler = new Handler();
  runnable = new Runnable() {
    @SuppressLint("DefaultLocale")
    @Override
    public void run() {
      handler.postDelayed(this, 1000);
      try {
        @SuppressLint("SimpleDateFormat") SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

        Date futureDate = dateFormat.parse(examTime);
        Date currentDate = new Date();
        if (!currentDate.after(futureDate)) {
          long difference = futureDate.getTime() - currentDate.getTime();

          long totalDays = difference / (24 * 60 * 60 * 1000);

          long day = TimeUnit.MILLISECONDS.toDays(difference);
          day %= 365;
          long month = day / 30;
          day %= 30;
          long hour = TimeUnit.MILLISECONDS.toHours(difference) - TimeUnit.DAYS.toHours(TimeUnit.MILLISECONDS.toDays(difference));
          long min = TimeUnit.MILLISECONDS.toMinutes(difference) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(difference));
          long sec = TimeUnit.MILLISECONDS.toSeconds(difference) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(difference));



          txt_month.setText("" + String.format("%02d", month));
          txt_day.setText("" + String.format("%02d", day));
          txt_hour.setText("" + String.format("%02d", hour));
          txt_min.setText("" + String.format("%02d", min));
          txt_scd.setText("" + String.format("%02d", sec));
          txt_mandeh.setText("" + String.format("%02d", totalDays) + " " + "روز تا زمان تعیین شده باقی‌ مانده است!");
          
        }
      } catch (Exception e) {
        e.printStackTrace();
      }
    }
  };
  handler.postDelayed(runnable, 1000);
}
