当我想将时间设置为00:00:00时，日历总是得到12:00:00
Calendar currentDate = Calendar.getInstance();
// even set AM_PM it was still 12:00:00
// currentDate.set(Calendar.AM_PM, Calendar.AM);
// Calendar.HOUR still not work
currentDate.set(Calendar.HOUR_OF_DAY, 0);
currentDate.set(Calendar.MINUTE, 0);
currentDate.set(Calendar.SECOND, 0);
currentDate.set(Calendar.MILLISECOND, 0);
我该怎么做？提前致谢。
最佳答案
但是，何时真正是00:00:00，何时开始呢？是今天吗还是昨天？
为了消除混乱，请尝试类似
Calendar currentDate = Calendar.getInstance();
// even set AM_PM it was still 12:00:00
// currentDate.set(Calendar.AM_PM, Calendar.AM);
// Calendar.HOUR still not work
currentDate.set(Calendar.HOUR_OF_DAY, 0);
currentDate.set(Calendar.MINUTE, 0);
currentDate.set(Calendar.SECOND, 1);
currentDate.set(Calendar.MILLISECOND, 0);
