Answer 1

I used Apache Commons StopWatch class. The default output of it's toString method is ISO8601-like, hours:minutes:seconds.milliseconds.

Example of Apache StopWatch

Answer 2

A real lazy way of doing this as long as you know you won't have more than 60 minutes is to just make a date and use SimpleDateFormat

public void onTick(long millisUntilFinished) {
     SimpleDateFormat dateFormat = new SimpleDateFormat("mm:ss");
     dateFormat.setTimeZone(TimeZone.getTimeZone("GMT"));
     Date date = new Date(millisUntilFinished);
     text.setText("Time left:" + dateFormat.format(date));
}

Answer 3

i'd use

org.apache.commons.lang.time.DurationFormatUtils.formatDuration(millisUntilFinished, "mm:ss")

Answer 4

You could do it using the standard Date formatting classes, but that might be a bit heavy-weight. I would just use the String.format method. For example:

int minutes = time / (60 * 1000);
int seconds = (time / 1000) % 60;
String str = String.format("%d:%02d", minutes, seconds);
