我不确定这是你想要的，但检查这个Android helper类

import android.text.format.DateUtils

例如:DateUtils.formatElapsedTime()

Android date duration elapsedtime

我使用Apache common的DurationFormatUtils，就像这样:

DurationFormatUtils.formatDuration(millis, "**H:mm:ss**", true);

下面是另一个如何格式化持续时间的示例。 注意，这个示例将正持续时间和负持续时间都显示为正持续时间。

import static java.time.temporal.ChronoUnit.DAYS;
import static java.time.temporal.ChronoUnit.HOURS;
import static java.time.temporal.ChronoUnit.MINUTES;
import static java.time.temporal.ChronoUnit.SECONDS;

import java.time.Duration;

public class DurationSample {
    public static void main(String[] args) {
        //Let's say duration of 2days 3hours 12minutes and 46seconds
        Duration d = Duration.ZERO.plus(2, DAYS).plus(3, HOURS).plus(12, MINUTES).plus(46, SECONDS);

        //in case of negative duration
        if(d.isNegative()) d = d.negated();

        //format DAYS HOURS MINUTES SECONDS 
        System.out.printf("Total duration is %sdays %shrs %smin %ssec.\n", d.toDays(), d.toHours() % 24, d.toMinutes() % 60, d.getSeconds() % 60);

        //or format HOURS MINUTES SECONDS 
        System.out.printf("Or total duration is %shrs %smin %sec.\n", d.toHours(), d.toMinutes() % 60, d.getSeconds() % 60);

        //or format MINUTES SECONDS 
        System.out.printf("Or total duration is %smin %ssec.\n", d.toMinutes(), d.getSeconds() % 60);

        //or format SECONDS only 
        System.out.printf("Or total duration is %ssec.\n", d.getSeconds());
    }
}

这个答案只使用Duration方法，适用于Java 8:

public static String format(Duration d) {
    long days = d.toDays();
    d = d.minusDays(days);
    long hours = d.toHours();
    d = d.minusHours(hours);
    long minutes = d.toMinutes();
    d = d.minusMinutes(minutes);
    long seconds = d.getSeconds() ;
    return 
            (days ==  0?"":days+" days,")+ 
            (hours == 0?"":hours+" hours,")+ 
            (minutes ==  0?"":minutes+" minutes,")+ 
            (seconds == 0?"":seconds+" seconds,");
}

在scala中，不需要库:

def prettyDuration(str:List[String],seconds:Long):List[String]={
  seconds match {
    case t if t < 60 => str:::List(s"${t} seconds")
    case t if (t >= 60 && t< 3600 ) => List(s"${t / 60} minutes"):::prettyDuration(str, t%60)
    case t if (t >= 3600 && t< 3600*24 ) => List(s"${t / 3600} hours"):::prettyDuration(str, t%3600)
    case t if (t>= 3600*24 ) => List(s"${t / (3600*24)} days"):::prettyDuration(str, t%(3600*24))
  }
}
val dur = prettyDuration(List.empty[String], 12345).mkString("")

在java8中还有另一种方法。但如果持续时间不超过24小时，则有效

public String formatDuration(Duration duration) {
    DateTimeFormatter formatter = DateTimeFormatter.ofPattern("h:mm.SSS");
    return LocalTime.ofNanoOfDay(duration.toNanos()).format(formatter);
}
