我是Android开发的新手。

我需要一个帮助来将当前时间转换为一个静态时间。

您的帮助将不胜感激。

我有一个这样的字符串

String created_at = "Wed Mar 03 19:37:35 +0000 2010";

我想将其转换为，这意味着当前时间和created_at字符串之间存在差异。

23 mins ago // Example

谢谢，

只需使用我创建的以下实用工具类并在其构造函数中传递两个date对象，然后使用getDifferenceString（）方法即可获取相同的对象。

 public class TimeDifference {
        int years;
        int months;
        int days;
        int hours;
        int minutes;
        int seconds;
        String differenceString;



        public TimeDifference(Date curdate, Date olddate) {

            float diff=curdate.getTime() - olddate.getTime();
            if (diff >= 0) {
                int yearDiff = Math.round( ( diff/ (365l*2592000000f))>=1?( diff/ (365l*2592000000f)):0);
                if (yearDiff > 0) {
                    years = yearDiff;
                    setDifferenceString(years + (years == 1 ? " year" : " years") + " ago");
                } else {
                    int monthDiff = Math.round((diff / 2592000000f)>=1?(diff / 2592000000f):0);
                    if (monthDiff > 0) {
                        if (monthDiff > 11)
                            monthDiff = 11;

                        months = monthDiff;
                        setDifferenceString(months + (months == 1 ? " month" : " months") + " ago");
                    } else {
                        int dayDiff = Math.round((diff / (86400000f))>=1?(diff / (86400000f)):0);
                        if (dayDiff > 0) {
                            days = dayDiff;
                            if(days==30)
                                days=29;
                            setDifferenceString(days + (days == 1 ? " day" : " days") + " ago");
                        } else {
                            int hourDiff = Math.round((diff / (3600000f))>=1?(diff / (3600000f)):0);
                            if (hourDiff > 0) {
                                hours = hourDiff;
                                setDifferenceString( hours + (hours == 1 ? " hour" : " hours") + " ago");
                            } else {
                                int minuteDiff = Math.round((diff / (60000f))>=1?(diff / (60000f)):0);
                                if (minuteDiff > 0) {
                                    minutes = minuteDiff;
                                    setDifferenceString(minutes + (minutes == 1 ? " minute" : " minutes") + " ago");
                                } else {
                                    int secondDiff =Math.round((diff / (1000f))>=1?(diff / (1000f)):0);
                                    if (secondDiff > 0)
                                        seconds = secondDiff;
