How to filter what will appear in the recyclerview

Question

I want to filter what gonna appear in the recyclerview is it possible ?

There is a CalendarView and i want that when someone clicks in a day from the calendarview, it shows itemviews just from that date, for example when someone click in day 15 of the month may, it shows just the tasks that is for that day

I do not know if is it possible. If someone can help me, it would be great.

Sorry for my english, it's google translate
