How To Make Gridlayout Scrollable

Question

I Have created a GridLayout with CardView inside a Viewpager. My layout was linear layout and to make it scrollable I wrapped whole in a ScrollView. But I can't scroll my screen. When I try to scroll nothing happens. How I can make these grids items scrollable. I am a beginner at android.

My Gridlayout XML File.
