I'm also trying to integrate the support library for GridLayout into my
application. To test the integration I created a small project where I
copied the layout from the previous post into the layout file. There are no
errors or anything but when I check the layout in the visual editor or by
running the test app on a device all 3 the elements (button, checkbox and
button) are placed on the first row side by side. But if I interpret the
XML correctly each element should be displayed on a single row and column.
So I'm wondering why the layout_column and layout_row attributes are
ignored.
Any suggestion how to fix this or what I'm doing wrong?
