手工划分，或者使用SimpleDateFormat API。

long start = System.currentTimeMillis();
// do your work...
long elapsed = System.currentTimeMillis() - start;
DateFormat df = new SimpleDateFormat("HH 'hours', mm 'mins,' ss 'seconds'");
df.setTimeZone(TimeZone.getTimeZone("GMT+0"));
System.out.println(df.format(new Date(elapsed)));

Edit by Bombe:评论中显示，这种方法只适用于较短的持续时间(即少于一天)。

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。

对于正确的字符串(“1小时，3秒”，“3分钟”，而不是“0小时，0分钟，3秒”)，我写这样的代码:

int seconds = (int)(millis / 1000) % 60 ;
int minutes = (int)((millis / (1000*60)) % 60);
int hours = (int)((millis / (1000*60*60)) % 24);
int days = (int)((millis / (1000*60*60*24)) % 365);
int years = (int)(millis / 1000*60*60*24*365);

ArrayList<String> timeArray = new ArrayList<String>();

if(years > 0)   
    timeArray.add(String.valueOf(years)   + "y");

if(days > 0)    
    timeArray.add(String.valueOf(days) + "d");

if(hours>0)   
    timeArray.add(String.valueOf(hours) + "h");

if(minutes>0) 
    timeArray.add(String.valueOf(minutes) + "min");

if(seconds>0) 
    timeArray.add(String.valueOf(seconds) + "sec");

String time = "";
for (int i = 0; i < timeArray.size(); i++) 
{
    time = time + timeArray.get(i);
    if (i != timeArray.size() - 1)
        time = time + ", ";
}

if (time == "")
  time = "0 sec";

回顾@brent-nash的贡献，我们可以使用模函数代替减法并使用String。结果字符串的格式方法:

  /**
   * Convert a millisecond duration to a string format
   * 
   * @param millis A duration to convert to a string form
   * @return A string of the form "X Days Y Hours Z Minutes A Seconds B Milliseconds".
   */
   public static String getDurationBreakdown(long millis) {
       if (millis < 0) {
          throw new IllegalArgumentException("Duration must be greater than zero!");
       }

       long days = TimeUnit.MILLISECONDS.toDays(millis);
       long hours = TimeUnit.MILLISECONDS.toHours(millis) % 24;
       long minutes = TimeUnit.MILLISECONDS.toMinutes(millis) % 60;
       long seconds = TimeUnit.MILLISECONDS.toSeconds(millis) % 60;
       long milliseconds = millis % 1000;

       return String.format("%d Days %d Hours %d Minutes %d Seconds %d Milliseconds",
                            days, hours, minutes, seconds, milliseconds);
   }

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)) 

这个主题已经被很好地覆盖了，我只是想分享我的函数，也许你可以使用这些函数，而不是导入整个库。

    public long getSeconds(ms) {
        return (ms/1000%60);
    }
    public long getMinutes(ms) {
        return (ms/(1000*60)%60);
    }
    public long getHours(ms) {
        return ((ms/(1000*60*60))%24);
    }
