Simple use it inside onscrollchanged method of recyclerview

I have a RecylcerView and a view which is above it and I want to hide it when I scroll down. I have found a way which kind of works, but it’s pretty janky and sometimes takes the speed out of the scrolling action. How do I make it more fluent?

Layout:

I want to hide the ChipGroup. There are more Chips in the group, but I removed them here.

Hide Code right now:

    final ChipGroup chipGroup = (ChipGroup) root.findViewById(R.id.chipGroup);
    mRecyclerView.setPadding(0, chipGroup.getHeight(), 0,0);

    mRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
        @Override
        public void onScrollStateChanged(@NonNull RecyclerView recyclerView, int newState) {
            if(newState == RecyclerView.SCROLL_STATE_IDLE){
                if(!showFilteredResults) {
                    showFilteredResults = true;
                }
            } else {
                if(showFilteredResults) {
                    showFilteredResults = false;
                }
            }
            super.onScrollStateChanged(recyclerView, newState);
        }

        @Override
        public void onScrolled(@NonNull RecyclerView recyclerView, int dx, int dy) {
            FrameLayout frameLayout = (FrameLayout) root.findViewById(R.id.frameLayout);
            if (dy > 0 && HIDE_VIEWS_ON_SCOLL) {
                // scrolling up
                Log.i("scroll", "up");
                TransitionManager.beginDelayedTransition(frameLayout, new ChangeBounds());
                chipGroup.setVisibility(View.GONE);
                mRecyclerView.setPadding(0, 0,0,0);
            } else if (dy < 0 && HIDE_VIEWS_ON_SCOLL){
                // scrolling down
                Log.i("scroll", "down");
                TransitionManager.beginDelayedTransition(frameLayout, new ChangeBounds());
                chipGroup.setVisibility(View.VISIBLE);
                mRecyclerView.setPadding(0, chipGroup.getHeight(),0,0);
            }

            super.onScrolled(recyclerView, dx, dy);
        }
    });
