Android CalendarView how to detect Month change

Question

I need to search my database basing the query on the month returned from a CalendarView. My problem is that onSelectedDayChange() event fires only when clicking, actually selecting a date not when the month is changed by swiping CalendarView. How to set up something like "onSelectedMonthChange"?

You can't do it with the Android CalendarView. Look at this thread.

If you want to do it, you will have to make custom CalendarView class which will extend CalendarView and implement onGestureListener. Keep a variable curMonth to keep account of your month. Whenever swipe left/right happen, update your month variable accordingly.

Thank you, I agree with your suggestion . How to test a fling on my PC? – alberto Sep 10 '17 at 15:19
@alberto Fling should work on an emulator (PC) as it's not multi-touch gesture. However, I advice mobile device to test gesture related stuff :-) – Sachin Aggarwal Sep 10 '17 at 23:51
hmm bad start already! public class FlingCalendaView extends CalendarView implements MyGestureListener {} show error "there is no default constructor available in 'Android.widget.CalendarView'" – alberto Sep 11 '17 at 04:04
Make a constructor of your own which will have an argument as context. – Sachin Aggarwal Sep 11 '17 at 06:59

if you want to show next and previous months in your calendar based on some click event, then you can do it as:

Calendar c = Calendar.getInstance();

//for next month
btnNext.onClick(){
     c.add(Calendar.MONTH,1);
}
//previous month
btnPrevious.onClick(){
     c.add(Calendar.MONTH,-1);
}
