public class CalendarView extends android.view.View implements View.OnCreateContextMenuListener, View.OnClickListener
This is the base class for a set of classes that implement views (day view and week view to start with) that share some common code.

mLastReloadMillis
This variable helps to avoid unnecessarily reloading events by keeping track of the start millis parameter used for the most recent loading of events. If the next reload matches this, then the events are not reloaded. To force a reload, set this to zero (this is set to zero in the method clearCachedEvents()).
