How to detect that RecyclerView rendered all holder?
Essence - I need to know when RecyclerView displayed to the user all visible elements
Why to set focus on the newly otrisovany element
The problem is that after calling notifyDatasetChanged from adapter RecyclerView redraw all of its elements, and they lose focus, it is transferred to the first element of activiti, and I need to fix it while drawing another element, then programmatically return on svezheokrashennym holder in the RecyclerView, but a full rendering it can be done. Accordingly, the focus should be set after everything is displayed on the screen.
