How to make Horizontal Scroll View inside Horizontal Recycler View work?

I have searched in similar questions and tried several answer without solving .. I have Horizontal Recycler View displaying city names and some data the problem is that I put canvas bar chart or RV chart as figure below inside Main Recycler View adapter at every position and to scroll this chart horizontally I put the chart in Horizontal Scroll View to see data of chart in long Horizontal direction while scrolling this chart from right to left and vise versa but actually it doesn't scroll Horizontal only Main Recycler view scroll Horizontal to display city when touch it and for this chart inside RV didn't scroll when touch it to scroll (freeze) is recycler view only scroll in horizontal and prevent any other scroll inside its child??

here is my recycler view item layout

I have tried to make Recycler View layout manger scroll vertically and the horizontal chart succeed to scroll horizontal but when make RV Horizontal the chart freeze without scrolling although it is inside Horizontal Scroll View

here is my RV

  recyclerViewWeather.setLayoutManager(new LinearLayoutManager(this, RecyclerView.HORIZONTAL, 
  false));
    adapter = new WeatherAdapter(this, cityList, dataManager);
   recyclerViewWeather.setHasFixedSize(true);
    recyclerViewWeather.setAdapter(adapter);

   recyclerViewWeather.addOnScrollListener(new RecyclerView.OnScrollListener() {
        @Override
        public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
            super.onScrollStateChanged(recyclerView, newState);
            if (newState == RecyclerView.SCROLL_STATE_IDLE){
               position = getCurrentItem();
               

                try {
                    UpdateDailyWeather();
                } catch (JSONException e) {
                    e.printStackTrace();
                }

            }
        }
    });
    PagerSnapHelper snapHelper = new PagerSnapHelper();
    snapHelper.attachToRecyclerView(recyclerViewWeather);

Wrap your WeatherChartViewBars in Horizontal LinearLayout inside HorizontalScrollView. It will work.
