Android CalendarView class cannot be found
I tried putting a Date Picker in my layout but instead of the DatePicker it only shows: DatePicker
and this error:
The following classes could not be found:
- DatePicker (Change to android.widget.DatePicker, Fix Build Path, Edit XML)
I don't know what this is because I already have a DatePicker in my app and it works fine just don't know why this one now isn't working.

I see what you are talking about in the Graphical Layout, but this won't affect your app. This error simply means Eclipse cannot build a preview of DatePicker for your layout. I bet if you run your app it will display just fine.
(As answered in this similar question)
You should change the api eclipse uses to graphically display your layout. You do this in the graphic view, in the top right, with the button that has the android logo. API 16 might give some problems, so try switching to 15 or 14 instead. (It will take a bit of time to load and refresh)
