Options for DatePicker to display or hide calendar view and spinners

The former exercise show a "Simple example of using DatePicker with both calendar view and spinners". We can show/hide calendar view and spinners individually in XML with android:calendarViewShown and android:spinnersShown attributes. Introduced in API level 11, we can also program it using Java code with setCalendarViewShown() and setSpinnersShown() methods.
