问题描述

我正在尝试创建一种自定义格式来显示经过的时间.

I'm trying to create an custom format to display the elapsed time.

现在我正在使用:

CharSequence relativeTimeSpan = DateUtils.getRelativeTimeSpanString(
     dateObject.getTime(), 
     System.currentTimeMillis(), 
     DateUtils.SECOND_IN_MILLIS,
     flags);

这会返回像这样的相对时间跨度:

This returns relative time spans like this:

• 1 分钟前
• 36 分钟前
• 4 小时前

...

我想要做的是显示这个，像这样:

What I'm trying to do is display this, like this:

• 1m
• 36m
• 4 小时

...

我知道 DateUtils 有 FORMAT_ABBREV_ALL 标志，但这并没有像我想要的那样缩写字符串......

I know DateUtils has FORMAT_ABBREV_ALL flag, but this doesn't abbreviate the string like I want to...

我怎样才能为此创建一些自定义的东西?

How can I create something custom for this ?

推荐答案

我已经在我的 twitter 模块中完成了这个

i have done this in my twitter module

public static String getTimeString(Date fromdate) {

    long then;
    then = fromdate.getTime();
    Date date = new Date(then);

    StringBuffer dateStr = new StringBuffer();

    Calendar calendar = Calendar.getInstance();
    calendar.setTime(date);
    Calendar now = Calendar.getInstance();

    int days = daysBetween(calendar.getTime(), now.getTime());
    int minutes = hoursBetween(calendar.getTime(), now.getTime());
    int hours = minutes / 60;
    if (days == 0) {

        int second = minuteBetween(calendar.getTime(), now.getTime());
        if (minutes > 60) {

            if (hours >= 1 && hours <= 24) {
                dateStr.append(hours).append("h");
            }

        } else {

            if (second <= 10) {
                dateStr.append("Now");
            } else if (second > 10 && second <= 30) {
                dateStr.append("few seconds ago");
            } else if (second > 30 && second <= 60) {
                dateStr.append(second).append("s");
            } else if (second >= 60 && minutes <= 60) {
                dateStr.append(minutes).append("m");
            }
        }
    } else

    if (hours > 24 && days <= 7) {
        dateStr.append(days).append("d");
    } else {
        dateStr.append(twtimeformat.format(date));
    }

    return dateStr.toString();
}

public static int minuteBetween(Date d1, Date d2) {
    return (int) ((d2.getTime() - d1.getTime()) / DateUtils.SECOND_IN_MILLIS);
}

public static int hoursBetween(Date d1, Date d2) {
    return (int) ((d2.getTime() - d1.getTime()) / DateUtils.MINUTE_IN_MILLIS);
}

public static int daysBetween(Date d1, Date d2) {
    return (int) ((d2.getTime() - d1.getTime()) / DateUtils.DAY_IN_MILLIS);
}
