Question

我有整数字段：

currentYear，currentMonth，currentDay，currentHour，currentMinute和nextYear，nextMonth，nextDay，nextHour，nextMinute。

如何以毫秒为单位及时获得这两个点之间的差异。我找到了一种使用Date（）对象的方法，但是这些函数似乎被删除了，所以风险很小。

还有其他方式吗？

Answer 1

使用GregorianCalendar创建日期，然后按照原样使用差异。

GregorianCalendar currentDay=new  GregorianCalendar (currentYear,currentMonth,currentDay,currentHour,currentMinute,0);
GregorianCalendar nextDay=new  GregorianCalendar (nextYear,nextMonth,nextDay,nextHour,nextMinute,0);

diff_in_ms=nextDay. getTimeInMillis()-currentDay. getTimeInMillis();

Answer 2

为Calendar和currenDay创建一个nextDay对象，将其转换为long，然后减去。例如：

Calendar currentDate = Calendar.getInstance();
Calendar.set(Calendar.MONTH, currentMonth - 1); // January is 0, Feb is 1, etc.
Calendar.set(Calendar.DATE, currentDay);
// set the year, hour, minute, second, and millisecond
long currentDateInMillis = currentDate.getTimeInMillis();

Calendar nextDate = Calendar.getInstance();
// set the month, date, year, hour, minute, second, and millisecond
long nextDateInMillis = nextDate.getTimeInMillis();

return nextDateInMillis - currentDateInMillis; // this is what you want

如果您不喜欢Calendar课程的混淆，可以查看Joda时间库。
