easy hack : u can use linearlayout manager instead of gridlayoutmanager. u can change item layout (layout each item in adpater ie:recycler_view_items)

something this

<linearlayout  background: set ur image>    <linearlayout>     // first item     </linearlayout>     <linearlayout>      //2nd item    </linearlayout>  <linearlayout> 

and change adapter set values accordingly. requires changing layout , adapter codes. work u u can set background each row

(ps: each row considered single item)
