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; else seconds = 1; setDifferenceString(seconds + (seconds == 1 ? " second" : " seconds") + " ago"); } } } } } } } public String getDifferenceString() { return differenceString; } public void setDifferenceString(String differenceString) { this.differenceString = differenceString; } public int getYears() { return years; } public void setYears(int years) { this.years = years; } public int getMonths() { return months; } public void setMonths(int months) { this.months = months; } public int getDays() { return days; } public void setDays(int days) { this.days = days; } public int getHours() { return hours; } public void setHours(int hours) { this.hours = hours; } public int getMinutes() { return minutes; } public void setMinutes(int minutes) { this.minutes = minutes; } public int getSeconds() { return seconds; } public void setSeconds(int seconds) { this.seconds = seconds; } }
