Android: Auto Refresh Google Maps

Question

Hi all,

I want to ask about how to auto refresh the Google Maps?

So i have an activity with radio button inside that user can choose about the interval of the auto refresh. Then I create a class with a map view with class that extends the CountDownTimer. The problem is MyCountDownTimer has a constructor that display it own interface. Here is my CountDownTimer class.

public class MyCountDownTimer extends CountDownTimer{   

    public MyCountDownTimer(long millisInFuture, long countDownInterval) {
        super(millisInFuture, countDownInterval);
        // TODO Auto-generated constructor stub
    }
    @Override
    public void onFinish() {
    //do something when finish
    }
    @Override
    public void onTick(long millisUntilFinished) {
    //do something when the interval is choosen
        LocationManager.requestLocationUpdate(GPS_PROVIDER, userChoosenInterval, 0, LcoationListener)
    }
}

how can i modify this class so my user can choose their own interval of auto refresh, or is there any other way around of how to auto-refresh the goole maps? thanks.

~Regards~
