Simple Gridview Tutorial Android Studio

If you are interested to create an application to donwload wallpaper or create your own gallery application you can use this tutorial as a base, maybe a lot of tutorials that you can get but this time I am trying to share some information about making custom adapter for gridview and send data int from activity to other activity then make the image feel full with CenterCrop ImageView.

I have a GridView in android which I fill it with data retrieved from a xml resource. For example I have 15 items in the GridView which are placed in order. The overall height exceeds the Screen height so i have to scroll to see the rest of the items. The problem is when I scroll back up, the order of the invisible rows have changed. It's a mysterious behavior as sometimes items swap rows with each other. 

Sir please help
