我是 Android 开发新手。

我需要一个帮助来将我的当前时间转换为一个静态时间。

感谢您的帮助。

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 ，这意味着我的当前时间和created_at字符串之间的差异。

23 mins ago // Example

谢谢

只需使用我创建的以下实用程序类并在其构造函数中传递两个日期对象。随后使用 getDifferenceString() 方法获取相同的结果。

 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");

                                if (minuteDiff > 0) {
                                    minutes = minuteDiff;
                                    setDifferenceString(minutes + (minutes == 1 ? " minute" : " minutes") + " ago");
                                } else {
                                    int secondDiff =Math.round((diff / (1000f))>=1?(diff / (1000f)):0);
