Java简单的时间戳到日期转换

问题描述

我今天一直在努力寻找这个问题的答案，但有很多相互矛盾的信息......

I've been trying to find the answer to this for a while today and there's just so much contradictory information....

我想做的是在 android 中获取当前的 unix 时间戳，然后将其转换为允许我 getHours() 和 getMinutes() 的格式.

What I'd like to do is get a current unix timestamp in android, and then convert it to a format that allows me to getHours() and getMinutes().

我目前正在这样做:

int time = (int) (System.currentTimeMillis());
Timestamp ts = new Timestamp(time);
mHour = ts.getHours();
mMinute = ts.getMinutes();

但它没有给我一个正确的小时或分钟值(它返回 03:38 代表当前东海岸时间 13:33).

But it's not giving me a correct value for hour or minute (it's returning 03:38 for the current East-coast time of 13:33).

推荐答案

这可行:

final Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(System.currentTimeMillis());
Date date = cal.getTime();
mHour = date.getHours();
mMinute = date.getMinutes();
