Question

如何计算两个日期之间的天数、小时数 (24)、分钟数 (60)、秒数 (60)。

我经历过

Android difference between Two Dates

How do I get difference between two dates in android?, tried every thing and post

但没有帮助，

这是我的代码..

  try {
        String FinalDate = "20-04-2018 08:00:00";
        String CurrentDate = "26-04-2018 10:10:30";
        Date date1;
        Date date2;

        SimpleDateFormat dates = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
        date1 = dates.parse(CurrentDate);
        date2 = dates.parse(FinalDate);

        /*long difference = date1.getTime() - date2.getTime();
        long differenceInMinutes = difference / (60 * 1000);
        long differenceInSeconds = difference / 1000;
        String strMinuteDifference = Long.toString(differenceInMinutes);
        String strSecondsDifference = Long.toString(differenceInSeconds);*/

        long difference = date1.getTime() - date2.getTime();
        long seconds = difference / 1000;
        long minutes = seconds / 60;
        long hours = minutes / 60;
        long days = hours / 24;


        Log.e("TAG_5", "CurrentDate is : " + date1);
        Log.e("TAG_5", "Final date is : " + date2);
        Log.e("TAG_5", "Day Difference: " + days);
        Log.e("TAG_5", "hours Difference: " + hours);
        Log.e("TAG_5", "Minute Difference: " + minutes);
        Log.e("TAG_5", "Seconds Difference: " + seconds);


    } catch (Exception exception) {
        Log.e("TAG_5", "exception " + exception);
    }

输出是

        E/TAG_5: CurrentDate is : Thu Apr 26 10:10:30 GMT+05:30 2018
        E/TAG_5: Demo date is : Fri Apr 20 08:00:00 GMT+05:30 2018
        E/TAG_5: Day Difference: 6
        E/TAG_5: hours Difference: 146
        E/TAG_5: Minute Difference: 8770
        E/TAG_5: Seconds Difference: 526230

代码似乎是计算这两个日期之间的所有小时、分钟、秒，但是

我希望输出像...小时应该是 2 小时、10 小时或 23 小时，但不能超过 24 小时，因为 25 小时将是新的一天，所以应该是 1 天 1 小时。

和分钟像 10 分钟 35 分钟或 59 分钟，但不超过 60

Seconds 也一样，应该是 12 秒、40 秒或 59 秒，但不能超过 60 秒。 那么我该如何实现呢？

Answer 1

像你说的那样计算“休息”时间。 (所以不到 24 小时)您可以使用模数。

In computing, the modulo operation finds the remainder after division of one number by another (sometimes called modulus).

int hours = theAmountOfHours % 24

在你的例子中

Log.e("TAG_5", "Day Difference: " + days);
Log.e("TAG_5", "hours Difference: " + hours % 24);
Log.e("TAG_5", "Minute Difference: " + minutes % 60);
Log.e("TAG_5", "Seconds Difference: " + seconds % 60);
