在项目中需要获取各式各样的时间,而且也会有很多地方会调用到这些方法,所以我将它们归集于一个文件中,方便之后的使用。
现在我们需要了解一些相对基础获取时间的方法。
1.获取当前日历对象:
Calendar calendar = Calendar.getInstance();
2.获取当前时区下日期时间对应的时间戳:
calendar.getTimeInMillis();
3.获取标准格林尼治时间下日期时间对应的时间戳:
long unixTime = calendar.getTimeInMillis();
unixTime - TimeZone.getDefault().getRawOffset();
4.获取当前日期对象:
Date date = new Date();
5.获取当前时区下日期时间对应的时间戳:
date.getTimeInMillis();
6.设置日期时间格式:
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
7.获取当前时区下日期时间对应的时间戳:
format.format(date);
现在来实现具体的方法。
1.获取时间戳:
public static long getTime() {
Calendar calendar = Calendar.getInstance();// 获取当前日历对象
long unixTime = calendar.getTimeInMillis();// 获取当前时区下日期时间对应的时间戳
return unixTime;
}
2.获取标准的时间:
public static String getStandardTime() {
SimpleDateFormat formatter = new SimpleDateFormat(BaseApplication.getInstance().getString(R.string.date_show_type_one));
Date curDate = new Date(System.currentTimeMillis());// 获取当前时间
return formatter.format(curDate);
}
3.获取与现在时间的时间差(秒):
public static int getDurationSecond(String time) {
int durationSecond = 0;
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date;
try {
date = df.parse(time);
MyLog.i("TimeUtils getDurationSecond Date=" + new Date().toString());
durationSecond = (int) ((new Date().getTime() - date.getTime()) / 1000);
} catch (Exception e) {
MyLog.e("TimeUtils getDurationSecond error=" + e);
}
return durationSecond;
}
4.获取时间差:
public static String getDuration(String one, String two) {
String duration = "";
SimpleDateFormat df = new SimpleDateFormat(<span style="font-family: SimHei;">"yyyy-MM-dd HH:mm:ss"</span>);
Date date1;
Date date2;
try {
date1 = df.parse(one);
date2 = df.parse(two);
int l = (int) ((date2.getTime() - date1.getTime()) / 1000 / 60);
if (l > 60) {
int hr = l / 60;
int min = l % 60;
duration = hr + "小时" + min + "分钟";
} else {
duration = l + "分钟";
}
} catch (Exception e) {
e.printStackTrace();
}
return duration;
}

Calendar calendar = Calendar.getInstance();// 获取当前日历对象
long unixTime = calendar.getTimeInMillis();// 获取当前时区下日期时间对应的时间戳
return unixTime;

//获取标准时间
