我修改了@MyKuLLSKI的回答，增加了多元化支持。我去掉了几秒，因为我不需要它们，如果你需要的话，可以重新添加。

public static String intervalToHumanReadableTime(int intervalMins) {

    if(intervalMins <= 0) {
        return "0";
    } else {

        long intervalMs = intervalMins * 60 * 1000;

        long days = TimeUnit.MILLISECONDS.toDays(intervalMs);
        intervalMs -= TimeUnit.DAYS.toMillis(days);
        long hours = TimeUnit.MILLISECONDS.toHours(intervalMs);
        intervalMs -= TimeUnit.HOURS.toMillis(hours);
        long minutes = TimeUnit.MILLISECONDS.toMinutes(intervalMs);

        StringBuilder sb = new StringBuilder(12);

        if (days >= 1) {
            sb.append(days).append(" day").append(pluralize(days)).append(", ");
        }

        if (hours >= 1) {
            sb.append(hours).append(" hour").append(pluralize(hours)).append(", ");
        }

        if (minutes >= 1) {
            sb.append(minutes).append(" minute").append(pluralize(minutes));
        } else {
            sb.delete(sb.length()-2, sb.length()-1);
        }

        return(sb.toString());          

    }

}

public static String pluralize(long val) {
    return (Math.round(val) > 1 ? "s" : "");
}

long time = 1536259;

return (new SimpleDateFormat("mm:ss:SSS")).format(new Date(time));

打印:

25:36:259

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";

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);
}

这个答案与上面的一些答案相似。然而，我觉得这将是有益的，因为与其他答案不同，这将删除任何额外的逗号或空格，并处理缩写。

/**
 * Converts milliseconds to "x days, x hours, x mins, x secs"
 * 
 * @param millis
 *            The milliseconds
 * @param longFormat
 *            {@code true} to use "seconds" and "minutes" instead of "secs" and "mins"
 * @return A string representing how long in days/hours/minutes/seconds millis is.
 */
public static String millisToString(long millis, boolean longFormat) {
    if (millis < 1000) {
        return String.format("0 %s", longFormat ? "seconds" : "secs");
    }
    String[] units = {
            "day", "hour", longFormat ? "minute" : "min", longFormat ? "second" : "sec"
    };
    long[] times = new long[4];
    times[0] = TimeUnit.DAYS.convert(millis, TimeUnit.MILLISECONDS);
    millis -= TimeUnit.MILLISECONDS.convert(times[0], TimeUnit.DAYS);
    times[1] = TimeUnit.HOURS.convert(millis, TimeUnit.MILLISECONDS);
    millis -= TimeUnit.MILLISECONDS.convert(times[1], TimeUnit.HOURS);
    times[2] = TimeUnit.MINUTES.convert(millis, TimeUnit.MILLISECONDS);
    millis -= TimeUnit.MILLISECONDS.convert(times[2], TimeUnit.MINUTES);
    times[3] = TimeUnit.SECONDS.convert(millis, TimeUnit.MILLISECONDS);
    StringBuilder s = new StringBuilder();
    for (int i = 0; i < 4; i++) {
        if (times[i] > 0) {
            s.append(String.format("%d %s%s, ", times[i], units[i], times[i] == 1 ? "" : "s"));
        }
    }
    return s.toString().substring(0, s.length() - 2);
}

/**
 * Converts milliseconds to "x days, x hours, x mins, x secs"
 * 
 * @param millis
 *            The milliseconds
 * @return A string representing how long in days/hours/mins/secs millis is.
 */
public static String millisToString(long millis) {
    return millisToString(millis, false);
}

我的简单计算是:

String millisecToTime(int millisec) {
    int sec = millisec/1000;
    int second = sec % 60;
    int minute = sec / 60;
    if (minute >= 60) {
        int hour = minute / 60;
        minute %= 60;
        return hour + ":" + (minute < 10 ? "0" + minute : minute) + ":" + (second < 10 ? "0" + second : second);
    }
    return minute + ":" + (second < 10 ? "0" + second : second);
}

快乐编码:)
