在代碼開發(fā)的時候，特別是那種論壇啊什么的要返回“幾秒前景馁，幾分鐘前板壮，幾小時前，幾天前合住，幾月前晶通，幾年前”這樣的時間格式汁针，服務(wù)端那邊只肯返回yyyy-MM-dd HH:mm:ss的格式哥遮，沒辦法镀裤，只能客戶端加個轉(zhuǎn)換了。

public class RelativeDateFormat {
    private static final long ONE_MINUTE = 60000L;
    private static final long ONE_HOUR = 3600000L;
    private static final long ONE_DAY = 86400000L;
    private static final long ONE_WEEK = 604800000L;

    private static final String ONE_SECOND_AGO = "秒前";
    private static final String ONE_MINUTE_AGO = "分鐘前";
    private static final String ONE_HOUR_AGO = "小時前";
    private static final String ONE_DAY_AGO = "天前";
    private static final String ONE_MONTH_AGO = "月前";
    private static final String ONE_YEAR_AGO = "年前";

    public static String format(String time) {
        SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        Date date = null;
        try {
            date = format.parse(time);
        } catch (ParseException e) {
            e.printStackTrace();
        }
        long delta = new Date().getTime() - date.getTime();
        if (delta < 1L * ONE_MINUTE) {
            long seconds = toSeconds(delta);
            return (seconds <= 0 ? 1 : seconds) + ONE_SECOND_AGO;
        }
        if (delta < 45L * ONE_MINUTE) {
            long minutes = toMinutes(delta);
            return (minutes <= 0 ? 1 : minutes) + ONE_MINUTE_AGO;
        }
        if (delta < 24L * ONE_HOUR) {
            long hours = toHours(delta);
            return (hours <= 0 ? 1 : hours) + ONE_HOUR_AGO;
        }
        if (delta < 48L * ONE_HOUR) {
            return "昨天";
        }
        if (delta < 30L * ONE_DAY) {
            long days = toDays(delta);
            return (days <= 0 ? 1 : days) + ONE_DAY_AGO;
        }
        if (delta < 12L * 4L * ONE_WEEK) {
            long months = toMonths(delta);
            return (months <= 0 ? 1 : months) + ONE_MONTH_AGO;
        } else {
            long years = toYears(delta);
            return (years <= 0 ? 1 : years) + ONE_YEAR_AGO;
        }
    }

    private static long toSeconds(long date) {
        return date / 1000L;
    }

    private static long toMinutes(long date) {
        return toSeconds(date) / 60L;
    }

    private static long toHours(long date) {
        return toMinutes(date) / 60L;
    }

    private static long toDays(long date) {
        return toHours(date) / 24L;
    }

    private static long toMonths(long date) {
        return toDays(date) / 30L;
    }

    private static long toYears(long date) {
        return toMonths(date) / 365L;
    }
}

調(diào)用的時候僚害，傳入時間String

        mTimeText.setText(RelativeDateFormat.format(time));
        System.out.print("time=" + time);
        System.out.print("format time=" + RelativeDateFormat.format(time));
