I see in some applications, I can choose a date and write some data there. I can see that added this data into the graphic on another page(or activity).
For instance, I can choose the date:09/09/2017 and number:5 etc. When I open graph page, I can see both of them.
I am asking that how can I pass the date? or how can I match the same date between two different page?
(actually, I want to use CalendarView in android studio and when I select a date, I should pass data into my timestamp which I use in android studio.)
