Conflict between ViewPager swipe and RecyclerView scroll

In my app, I have a ViewPager that has different tabs. Each tab is composed only of a RecyclerView which can be scrolled vertically.

My problem is that when I try to navigate to other tab and swipe left or right, the RecyclerView's scroll is detected first and instead of going to another tab the RecyclerView gets scrolled.

I tried following property of recycler view:

         rv_home.setNestedScrollingEnabled(false);

that time ViewPager swipe works as expected But vertical scrolling of recycler view disabled. What should I do?

rv_home.setHasFixedSize(true);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getApplicationContext(),
LinearLayoutManager.VERTICAL, false);
layoutManager.setAutoMeasureEnabled(true);
rv_home.setNestedScrollingEnabled(false);
rv_home.setLayoutManager(layoutManager);

try this

 rootView.nested_scroll.setOnScrollChangeListener(object : NestedScrollView.OnScrollChangeListener {
        override fun onScrollChange(
            v: NestedScrollView?,
            scrollX: Int,
            scrollY: Int,
            oldScrollX: Int,
            oldScrollY: Int
        ) {

            if (v?.getChildAt(v.getChildCount() - 1) != null) {
                if ((scrollY >= (v.getChildAt(v.getChildCount() - 1).getMeasuredHeight() - v.getMeasuredHeight())) &&
                    scrollY > oldScrollY
                ) {
                    var visibleItemCount = (recyclerView.layoutManager as LinearLayoutManager).getChildCount()
                    var totalItemCount = (recyclerView.layoutManager as LinearLayoutManager).getItemCount()
                    var pastVisiblesItems =
                        (recyclerView.layoutManager as LinearLayoutManager).findFirstVisibleItemPosition()

                    if ((visibleItemCount + pastVisiblesItems) >= totalItemCount) {
                //Load Your Items Here

                    }
                }
            }
        }
    })

Its because you might have taken RecyclerView item as match parent in width. Take that wrap content and it might work for you as well as it worked for me.
