i find this , but this doesn't help me. Any help would be appreciated.

Add this where ever you want to scroll your recycler view

 recyclerView.scrollToPosition(position)
    recyclerView.post {
        var view = recyclerView.layoutManager?.findViewByPosition(position);
        if (view == null) {
          // do nothing
        }

        var snapDistance = snapHelper.calculateDistanceToFinalSnap(recyclerView.layoutManager!!, view!!)
        if (snapDistance?.get(0)   != 0 || snapDistance[1] != 0) {
            recyclerView.scrollBy(snapDistance?.get(0)!!, snapDistance?.get(1));
        }
    }

By using this LinearSnap Helper which is attached to your recycler view

  var snapHelper = LinearSnapHelper()
    snapHelper.attachToRecyclerView(recyclerView)
