how to change format of chronometer?

Question

One of my problem is of changing the format of chronometer in android. i have the problem that chronometer shows its time in 00:00 format and i want it to come in 00:00:00 f

Answer 1

In Kotlin, found a better solution with no memory allocation for the String every second

cm_timer.format = "00:%s"
cm_timer.setOnChronometerTickListener({ cArg ->
            val elapsedMillis = SystemClock.elapsedRealtime() - cArg.base
            if (elapsedMillis > 3600000L) {
                cArg.format = "0%s"
            }
            else {
                cArg.format = "00:%s"
            }
        })

where cm_timer is Chronometer
