如何在日历中将时间设置为 24 小时格式

2022-01-11 00:00:00 calendar java

我需要将时间设置在当前日期.时间字符串始终为 24 小时格式，但我得到的结果是错误的:

I need to set the time on the current date. The time string is always in 24 hour format but the result I get is wrong:

  SimpleDateFormat df = new SimpleDateFormat("kk:mm");
  Date d1 = df.parse("10:30");
  Calendar c1 = Calendar.getInstance();
  c1.set(Calendar.HOUR, d1.getHours());
  c1.set(Calendar.MINUTE, d1.getMinutes());

日期应该是今天的日期，时间设置为 10:30.相反，c1 中的时间最终是 22:30.如何强制日历控件识别我的时间是 24 小时格式?

The date should be today's date and the time set to 10:30. Instead the time in c1 ends up being 22:30. How can I force the calendar control to recognize my time is 24 hour format?

如果我这样做:

Calendar c1 = Calendar.getInstance();
c1.set(Calendar.HOUR, 10);
c1.set(Calendar.MINUTE, 30);

这给了我同样的结果.为什么?

This gives me the same result. Why?

推荐答案

替换这个:

c1.set(Calendar.HOUR, d1.getHours());

用这个:

c1.set(Calendar.HOUR_OF_DAY, d1.getHours());

Calendar.HOUR 严格为 12 小时.

Calendar.HOUR is strictly for 12 hours.
