Color cell in calendar view

问题:

I use calendarView and now I want to change a background color in some calender cells. How can I do this? Or maybe somebody knows how to setting a listener in some cell in view? I tried like this:

(ListView) calendar.findViewById(android.R.id.list);

to find a list in widget, some id was back, but listener doesn't works. Same problem when I want to click on current day in view.
