Prevent paging/swiping in cascaded ViewPager while handle scrolling of contained RecyclerView:

Question

I have a ViewPager with 3 Fragments contained in it. One of the Fragments contains another ViewPager. which makes it a cascaded ViewPager inside a ViewPager.

I need to prevent the inner ViewPager from swiping/paging while allow it to pass the scroll gestures to the contained RecyclerView.

Yes I'm well aware that a ViewPager inside a ViewPager is not a great idea, yet in this case the view pager should no swipe but pass the gestures down to the child views. So there should not be a problem of two swipe mechanism in the same directions.

I tried to use the following NonSwipeableViewPager code for the inner view pager:

public class NonSwipeableViewPager extends ViewPager {

  public NonSwipeableViewPager(Context context) {
        super(context);
    }

    public NonSwipeableViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        // Never allow swiping to switch between pages
        return false;
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        // Never allow swiping to switch between pages
        return false;
    }
}

And this indeed stops the ViewPager from paging/swiping but also prevents it from passing the touch events down to the RecyclerView.

How can I change this ViewPager to consume the swiping/paging gesture yet pass the scrolling gesture to the RecyclerView?
