RecyclerView - How to smooth scroll to top of item on a certain position?

RecyclerView is designed to be extensible, so there is no need to subclass the LayoutManager (as droidev suggested) just to perform the scrolling.

Instead, just create a SmoothScroller with the preference SNAP_TO_START:

RecyclerView.SmoothScroller smoothScroller = new LinearSmoothScroller(context) {  @Override protected int getVerticalSnapPreference() {    return LinearSmoothScroller.SNAP_TO_START;  }};

Now you set the position where you want to scroll to:

smoothScroller.setTargetPosition(position);

and pass that SmoothScroller to the LayoutManager:

layoutManager.startSmoothScroll(smoothScroller);

for this you have to create a custom LayoutManager

public class LinearLayoutManagerWithSmoothScroller extends LinearLayoutManager {    public LinearLayoutManagerWithSmoothScroller(Context context) {        super(context, VERTICAL, false);    }    public LinearLayoutManagerWithSmoothScroller(Context context, int orientation, boolean reverseLayout) {        super(context, orientation, reverseLayout);    }    @Override    public void smoothScrollToPosition(RecyclerView recyclerView, RecyclerView.State state,                                       int position) {        RecyclerView.SmoothScroller smoothScroller = new TopSnappedSmoothScroller(recyclerView.getContext());        smoothScroller.setTargetPosition(position);        startSmoothScroll(smoothScroller);    }    private class TopSnappedSmoothScroller extends LinearSmoothScroller {        public TopSnappedSmoothScroller(Context context) {            super(context);        }        @Override        public PointF computeScrollVectorForPosition(int targetPosition) {            return LinearLayoutManagerWithSmoothScroller.this                    .computeScrollVectorForPosition(targetPosition);        }        @Override        protected int getVerticalSnapPreference() {            return SNAP_TO_START;        }    }}

use this for your RecyclerView and call smoothScrollToPosition.

example :

 recyclerView.setLayoutManager(new LinearLayoutManagerWithSmoothScroller(context)); recyclerView.smoothScrollToPosition(position);

this will scroll to top of the RecyclerView item of specified position.

hope this helps.

This is an extension function I wrote in Kotlin to use with the RecyclerView (based on @Paul Woitaschek answer):

fun RecyclerView.smoothSnapToPosition(position: Int, snapMode: Int = LinearSmoothScroller.SNAP_TO_START) {  val smoothScroller = object : LinearSmoothScroller(this.context) {    override fun getVerticalSnapPreference(): Int = snapMode    override fun getHorizontalSnapPreference(): Int = snapMode  }  smoothScroller.targetPosition = position  layoutManager?.startSmoothScroll(smoothScroller)}

Use it like this:

myRecyclerView.smoothSnapToPosition(itemPosition)
