Problem with GridView

[Arash-gm]

i'm implementing Parallax effect on one of my fragments , that contains of an ImageView and a GridView below that. if i use wrap_content for my GridView it's height change to just one row of my grid and there is no parallax effect , but if i use a fixed height for GridView it would be working. how can i make it work with wrap_content?
