For StickyHeadersLayoutManager to work, your recyclerview needs to have constant height, or match_parent or have a height of 0 and a layout_weight of some non-zero value. StickyHeadersLayoutManager expects to scroll, and if you use wrap_content, you will by definition not get scrolling behavior.

If you want sectioning layout but want wrap_content behavior, you can use SectioningAdapter, but use a vanilla LinearLayoutManager.
