Add view to ViewGroup only if there is enough space left

I have scrollable horizontal RecyclerView filled with same size items.

I need to change behaviour of that ViewGroup and have 4 requirements:

• not scrollable
• as many items as space left (all items needs to be displayed with full size)
• if there is more items to display than space left - show "ellipsize" item at the end
• items takes equal space (similar to layout_constraintHorizontal_chainStyle=”spread”)

I tried to play with Flexbox-layout but I am not sure if this is a correct tool to achieve it. Also before I started trying to implement it by myself (measure; add item if space left > item.size), I wanted to ask if there is already easy solution for this.

I have created EllipsizeViewGroup for that. Layout is based on LinearLayout. You can add more views dynamically.
