I need help to add a space inside a GridView at the bottom of it. This Space should be below the last Element of the GridView, inside of it. This space shouldn't work like a margin to the next element, it should be only visible, when the user scrolles to the bottom of the GridView. The reason for this is an ad banner which partly covers the bottom of the GridView. Besides this obstruction, the user should still be able to see the whole content of the GridView, that's why the space at the bottom of the GridView is needed.
left: ad (blue) covers part of GridView elements (orange); right: ad covers the space in the bottom of the GridView
Example, how it will look like, just imagine that the space is at the bottom, not at the top.
So far I tried to work with the Padding and Marging Variables for Bottom, but they are not the right variables for the problem. I also searched through stackoverflow, I found some similar questions like: Add extra space to bottom of a GridView or ListView or: Adding a footer View to a multi-column GridView in Android?. But the solutions doesn't seem to fit my case and furthermore I am searching for a solution inside the layout file and not inside the source code (if there is any of course).
Your help is very much appreciated.
