enter image description here

let me explain this. need same layout. first grid cell rowspan = 2. can see on screenshot.
may ask me, why ask question if post desired result.
here 1 problem, current orientation of layout manager vertical, may notice gray space under layout. there 3 items in recycler view.
if add more 3 that, depending on specified height.
enter image description here

what need need have same result on first screenshot,but horizontal scroll.

if change layout manager orientation horizontal following result.

enter image description here

of course can play row , colspans desired result, different on each screen dimension.

i need first 3 items of list same on first screenshot, ability scroll horizontally if there more 3 items.
must scaled independently screen orientation, dimension, works vertical layout manager orientation. there shouldn't appear fourth, fifth item if there enough space 3 , in such layout.

i have tried play colspans , rowspans, layoutmanager implementation, layout params (match parent, wrap content) , other. haven't got desired result.

please such result, or @ least can set in code.
