Show float number of pages

I need to show 1 row of elements but in this order: the first, and half of the second... or the first, the second and half of the third... but without loses the scale of the element... is possible to do that?

Start by reading the pager-layoutmanager Android library and its RecyclerView layout behavior; the issue provides no file or test entry point. Compare the layout with the attached screenshot and determine how to show a partial next item without changing item scale. Done means the requested ordering and partial-page display are supported.
