Why isn't the onDraw() method of my custom view being called when the size
of the view is set larger than the screen (it is inside a scroll...

Inside a method of my Fragment, I do the following in order to add a
custom calendar to a container:
container.addView(calView = new CalendarView(x, y, z));
calView.setMinimumHeight(height);
If "height" is large enough that container is expanded to larger than the
scrollview, the scroll bar appears as it should, but the calendar is not
drawn (the onDraw() method is never called).
