android格式化时间中文版,Android小工具之智能格式化时间

看着别人的应用的时间显示着“刚刚”、“2分钟之前”、“下午 2:00”是不是很羡慕？但是常常因为项目时间紧凑，没空去扣这些细节的你一定很想要一个这样的小工具啦，这里就送大家一个这样的格式化时间小工具：

Gist点这里

import java.text.SimpleDateFormat;

import java.util.Calendar;

import java.util.Date;

import java.util.GregorianCalendar;

import java.util.Locale;

/**

* Created by solo on 15/4/11.

*/

public class DateUtils {

public static String formatDateTime(Date date) {

String text;

long dateTime = date.getTime();

if (isSameDay(dateTime)) {

Calendar calendar = GregorianCalendar.getInstance();

if (inOneMinute(dateTime, calendar.getTimeInMillis())) {

return "刚刚";

} else if (inOneHour(dateTime, calendar.getTimeInMillis())) {

return String.format("%d分钟之前", Math.abs(dateTime - calendar.getTimeInMillis()) / 60000);

} else {

calendar.setTime(date);

int hourOfDay = calendar.get(Calendar.HOUR_OF_DAY);

if (hourOfDay > 17) {

text = "晚上 hh:mm";

} else if (hourOfDay >= 0 && hourOfDay <= 6) {

text = "凌晨 hh:mm";

} else if (hourOfDay > 11 && hourOfDay <= 17) {

text = "下午 hh:mm";

} else {

text = "上午 hh:mm";

}

}

} else if (isYesterday(dateTime)) {

text = "昨天 HH:mm";

} else if (isSameYear(dateTime)) {

text = "M月d日 HH:mm";

} else {

text = "yyyy-M-d HH:mm";

}

// 注意，如果使用android.text.format.DateFormat这个工具类，在API 17之前它只支持adEhkMmszy

return new SimpleDateFormat(text, Locale.CHINA).format(date);

}

private static boolean inOneMinute(long time1, long time2) {

return Math.abs(time1 - time2) < 60000;

}

private static boolean inOneHour(long time1, long time2) {

return Math.abs(time1 - time2) < 3600000;

}

private static boolean isSameDay(long time) {

long startTime = floorDay(Calendar.getInstance()).getTimeInMillis();

long endTime = ceilDay(Calendar.getInstance()).getTimeInMillis();

return time > startTime && time < endTime;

}

private static boolean isYesterday(long time) {

Calendar startCal;

startCal = floorDay(Calendar.getInstance());

startCal.add(Calendar.DAY_OF_MONTH, -1);

long startTime = startCal.getTimeInMillis();

Calendar endCal;

endCal = ceilDay(Calendar.getInstance());

endCal.add(Calendar.DAY_OF_MONTH, -1);

long endTime = endCal.getTimeInMillis();

return time > startTime && time < endTime;

}

private static boolean isSameYear(long time) {

Calendar startCal;

startCal = floorDay(Calendar.getInstance());

startCal.set(Calendar.MONTH, Calendar.JANUARY);

startCal.set(Calendar.DAY_OF_MONTH, 1);

return time >= startCal.getTimeInMillis();

}

private static Calendar floorDay(Calendar startCal) {

startCal.set(Calendar.HOUR_OF_DAY, 0);

startCal.set(Calendar.MINUTE, 0);

startCal.set(Calendar.SECOND, 0);

startCal.set(Calendar.MILLISECOND, 0);

return startCal;

}

private static Calendar ceilDay(Calendar endCal) {

endCal.set(Calendar.HOUR_OF_DAY, 23);

endCal.set(Calendar.MINUTE, 59);

endCal.set(Calendar.SECOND, 59);

endCal.set(Calendar.MILLISECOND, 999);

return endCal;

}

}

代码很简单，一看就懂的。
