我不会为此引入额外的依赖项(毕竟，除法并不那么难)，但如果您无论如何都在使用Commons Lang，还有DurationFormatUtils。

用法示例(从这里改编):

import org.apache.commons.lang3.time.DurationFormatUtils

public String getAge(long value) {
    long currentTime = System.currentTimeMillis();
    long age = currentTime - value;
    String ageString = DurationFormatUtils.formatDuration(age, "d") + "d";
    if ("0d".equals(ageString)) {
        ageString = DurationFormatUtils.formatDuration(age, "H") + "h";
        if ("0h".equals(ageString)) {
            ageString = DurationFormatUtils.formatDuration(age, "m") + "m";
            if ("0m".equals(ageString)) {
                ageString = DurationFormatUtils.formatDuration(age, "s") + "s";
                if ("0s".equals(ageString)) {
                    ageString = age + "ms";
                }
            }
        }
    }
    return ageString;
}   

例子:

long lastTime = System.currentTimeMillis() - 2000;
System.out.println("Elapsed time: " + getAge(lastTime)); 

//Output: 2s

注意:从两个LocalDateTime对象中获取millis可以使用:

long age = ChronoUnit.MILLIS.between(initTime, LocalDateTime.now())

对于那些寻找Kotlin代码的人:

fun converter(millis: Long): String =
        String.format(
            "%02d : %02d : %02d",
            TimeUnit.MILLISECONDS.toHours(millis),
            TimeUnit.MILLISECONDS.toMinutes(millis) - TimeUnit.HOURS.toMinutes(
                TimeUnit.MILLISECONDS.toHours(millis)
            ),
            TimeUnit.MILLISECONDS.toSeconds(millis) - TimeUnit.MINUTES.toSeconds(
                TimeUnit.MILLISECONDS.toMinutes(millis)
            )
        )

示例输出:09:10:26

适用于API 9以下的Android

(String.format("%d hr %d min, %d sec", millis/(1000*60*60), (millis%(1000*60*60))/(1000*60), ((millis%(1000*60*60))%(1000*60))/1000)) 

    long startTime = System.currentTimeMillis();
    // do your work...
    long endTime=System.currentTimeMillis();
    long diff=endTime-startTime;       
    long hours=TimeUnit.MILLISECONDS.toHours(diff);
    diff=diff-(hours*60*60*1000);
    long min=TimeUnit.MILLISECONDS.toMinutes(diff);
    diff=diff-(min*60*1000);
    long seconds=TimeUnit.MILLISECONDS.toSeconds(diff);
    //hour, min and seconds variables contains the time elapsed on your work

这在Java 9中更容易:

    Duration elapsedTime = Duration.ofMillis(millisDiff );
    String humanReadableElapsedTime = String.format(
            "%d hours, %d mins, %d seconds",
            elapsedTime.toHours(),
            elapsedTime.toMinutesPart(),
            elapsedTime.toSecondsPart());

这将生成像0小时39分9秒这样的字符串。

如果你想在格式化前舍入整秒:

    elapsedTime = elapsedTime.plusMillis(500).truncatedTo(ChronoUnit.SECONDS);

如果小时数为0，则省略:

    long hours = elapsedTime.toHours();
    String humanReadableElapsedTime;
    if (hours == 0) {
        humanReadableElapsedTime = String.format(
                "%d mins, %d seconds",
                elapsedTime.toMinutesPart(),
                elapsedTime.toSecondsPart());

    } else {
        humanReadableElapsedTime = String.format(
                "%d hours, %d mins, %d seconds",
                hours,
                elapsedTime.toMinutesPart(),
                elapsedTime.toSecondsPart());
    }

现在我们有39分9秒。

要打印前导0的分钟和秒，使它们始终是两个数字，只需在相关的格式说明符中插入02，如下所示:

    String humanReadableElapsedTime = String.format(
            "%d hours, %02d mins, %02d seconds",
            elapsedTime.toHours(),
            elapsedTime.toMinutesPart(),
            elapsedTime.toSecondsPart());

现在我们有0小时39分09秒。

对于一小时以内的小时间，我更喜欢:

long millis = ...

System.out.printf("%1$TM:%1$TS", millis);
// or
String str = String.format("%1$TM:%1$TS", millis);

对于较长的间隔:

private static final long HOUR = TimeUnit.HOURS.toMillis(1);
...
if (millis < HOUR) {
    System.out.printf("%1$TM:%1$TS%n", millis);
} else {
    System.out.printf("%d:%2$TM:%2$TS%n", millis / HOUR, millis % HOUR);
}
