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.
