(Smooth)ScrollToPosition doesn't work properly with RecyclerView

Question

Finally I was able to make it work! LinearLayoutManager.scrollToPositionWithOffset(int, int) did the trick.

I also have same issue, but managed to fix the issue by Customizing SmoothScroller

let Custom LayoutManager as below

public class CustomLayoutManager extends LinearLayoutManager {
    private static final float MILLISECONDS_PER_INCH = 50f;
    private Context mContext;

    public CustomLayoutManager(Context context) {
        super(context);
        mContext = context;
    }

    @Override
    public void smoothScrollToPosition(RecyclerView recyclerView,
        RecyclerView.State state, final int position) {

        LinearSmoothScroller smoothScroller = 
            new LinearSmoothScroller(mContext) {

            //This controls the direction in which smoothScroll looks
            //for your view
            @Override
            public PointF computeScrollVectorForPosition
            (int targetPosition) {
                return CustomLayoutManager.this
                    .computeScrollVectorForPosition(targetPosition);
            }

            //This returns the milliseconds it takes to 
            //scroll one pixel.
            @Override
            protected float calculateSpeedPerPixel
                (DisplayMetrics displayMetrics) {
                return MILLISECONDS_PER_INCH/displayMetrics.densityDpi;
            }
        };

        smoothScroller.setTargetPosition(position);
        startSmoothScroll(smoothScroller);
    }
}

(documentation commented inside the code given above)Please set the above LayoutManager to the recyerview

CustomLayoutManagerlayoutManager = new CustomLayoutManager(getActivity());
recyclerView.setLayoutManager(layoutManager);
recyclerView.smoothScrollToPosition(position);

by using the custom Layout manager

scrollToPosition also working well in my case u can use

recyclerView.scrollToPosition(position)

also if you want to adjust the speed of smoothScrollToPosition please override the

private static final float MILLISECONDS_PER_INCH = 50f;

in CustomLayoutManager. So if we put the value as 1f the smoothScrollToPosition will be faster like scrollToPosition.increasing value make delay and decreasing will make the speed of scroll. Hope this will useful.

In My case,

`mRecyclerView.scrollToPosition(10);` 

also did not work. But

`mRecyclerView.smoothScrollToPosition(10);` 

works fine for me...

To scroll down smoothly to bottom from any position in the RecyclerView on clicking EditText.

edittext.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                rv_commentList.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                      rv_commentList.scrollToPosition(rv_commentList.getAdapter().getItemCount() - 1);
                    }
                }, 1000);
            }
        });

Another reason why any of the before mentioned solutions may not work is if your RecyclerView is embedded in a NestedScrollView. In this case you have to call the scroll action on the NestedScrollView.

for example:

nestedScrollview.smoothScrollTo(0,0)
