Pro RecyclerView
summary
Explains RecyclerView internals: a layout manager, item animator and adapter coordinate to position and animate items; stable IDs plus SortedList and upcoming DiffUtil calculate precise moves so updates animate instead of jumping; ItemTouchHelper and SnapHelper sit outside RecyclerView and reuse public APIs; common pitfalls include requestLayout from ImageView/TextView causing full relayout, asynchronous binding (use executePendingBindings), image aspect-ratio sizing to avoid jumps, and always update adapter on the main thread to avoid crashes.
