here countdown timer:

questioncountdowntimer

public class questioncountdowntimer extends countdowntimer { private textview remainingtimedisplay; private context context; public questioncountdowntimer(context context,long millisinfuture, long countdowninterval,textview remainingtimedisplay) { super(millisinfuture, countdowninterval); this.context = context; this.remainingtimedisplay = remainingtimedisplay; } @override public void ontick(long millisuntilfinished) { long millis = millisuntilfinished; string hms = string.format("%02d:%02d", timeunit.milliseconds.tominutes(millis) - timeunit.hours.tominutes(timeunit.milliseconds.tohours(millis)), timeunit.milliseconds.toseconds(millis) - timeunit.minutes.toseconds(timeunit.milliseconds.tominutes(millis))); remainingtimedisplay.settext(hms); } @override public void onfinish() { toast.maketext(context,"countdown finish :)",toast.length_short).show(); } }

note: textview remainingtimedisplay

remainingtimedisplay.settext(hms); utilize display remaining time using textview

here phone call timer:

//start quiz timer questioncountdowntimer timer = new questioncountdowntimer(this,10000, 1000, remainingtimedisplay); timer.start();

-first parameter: - utilize context show toast message

-second parameter: 10000 - total time (10 sec)

-third parameter: 1000 - countdown interval (1 sec)

-last parameter: dispaly remaining time in real time
