im trying to figure out how i can make this work. I have perfectly working wallpaper selector, Which loads the wallpaper as a [1]:https://www.dropbox.com/s/phu0a6atue7vlsb/Screenshot_2013-01-03-23-35-06.png
However im trying to change the code to look something like this! The main interface like so. https://www.dropbox.com/s/0v0wd9sx41nh2oh/Screenshot_2013-01-03-23-38-34.png
And when the "Wallpaper" is selected it bring up a ImageView of the large wallpaper https://www.dropbox.com/s/dna7xxa1hzywwme/Screenshot_2013-01-03-23-38-55.png
Here is what i have for soure code.
Im suck on getting it changed from a Gallery to a GridView!

I've should some of the following resources GridView | Android Developers:http://developer.android.com/guide/topics/ui/layout/gridview.html And a few others, I attempt to change everything over put end up bricking the entire code.
Any Help by Tips, Code, Example, Links, Support i'd extremely appreciate it all, Thank you.
