Try This :

recyclerViewOne.addOnItemTouchListener(new RecyclerTouchListener(this, recyclerView, new RecyclerTouchListener.ClickListener() {
    @Override
    public void onClick(View view, int position) {

        Product allEventDatum = productList.get(position);
        categoryss = allEventDatum.getCategory();

        // get your first item from first recycler view and save it in string/int
        // then pass that stored value to your API to get data according to get relevant data in the second recycler view

    }

    @Override
    public void onLongClick(View view, int position) {

    }
}));
