Here's a simple program that puts a bunch of GridViews inside a
ListView. My original question was about how the list item that has no
GridView entries, or one row of entries, still has two rows. But, upon
further examination of the included program, the worse problem is that
the GridView items that have 3 rows are cut off. The ListView is not
giving enough space to include the entire height of the taller
GridView.
Sometimes the GridViews with 3 rows can be scrolled, sometimes not.
The intention, in my real code, is to put out a variable length list
in a grid fashion and it mostly works, but for the scrolling that is
sometimes required.
Is it possible to get the GridViews to come out full size, even at the
expense of all the item views in the ListView being larger? How could
I do that?
