LinearSmoothScroller

open class LinearSmoothScroller : RecyclerView.SmoothScroller(source)

RecyclerView.SmoothScroller implementation which uses a LinearInterpolator until the target position becomes a child of the RecyclerView and then uses a DecelerateInterpolator to slowly approach to target position.

If the RecyclerView.LayoutManager you are using does not implement the RecyclerView.SmoothScroller.ScrollVectorProvider interface, then you must override the computeScrollVectorForPosition method. All the LayoutManagers bundled with the support library implement this interface.
