    mediaAdapter = new MediaDiscoverAdapter(getActivity(), mediaCallbackListener);
    discoverBinding.rcMedia.setNestedScrollingEnabled(false);
    discoverBinding.nestedScroll.setFillViewport(true);
    discoverBinding.rcMedia.setAdapter(mediaAdapter);
    layoutManager = new StickyHeaderLayoutManager();
    layoutManager.setAutoMeasureEnabled(true);
    discoverBinding.rcMedia.setLayoutManager(layoutManager);

I figure out the solution with the help of StackOverFlow. I just make Viewpager part of RecycleView as row item using getItemViewType and removed the NestedScrollView so now layout looks like..

mainLayout.xml

<data>

    <variable
        name="MediaDiscoverFragmentNew"
        type="com.hpc.fragments.media.MediaDiscoverFragmentNew" />
</data>


<android.support.v4.widget.SwipeRefreshLayout
    android:id="@+id/swipe_refresh"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">


    <android.support.v7.widget.RecyclerView
        android:id="@+id/rc_media"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />


</android.support.v4.widget.SwipeRefreshLayout>

and created two separate item xmls raw_media_top.xml for top Viewpager and another raw_media.xml for rest of items.

      if(viewType == HEADER_VIEW) {
        RawMediaTopBinding mediaTopBinding = 
        DataBindingUtil.inflate(mLayoutInflater, R.layout.raw_media_top, parent, false);
        mediaTopBinding.setMediaDiscoverAdapterNew(this);
        return new HeaderViewHolder(mediaTopBinding);
    } else {
        RawMediaBinding inspirationItemsBinding = DataBindingUtil.inflate(mLayoutInflater, R.layout.raw_media, parent, false);
        inspirationItemsBinding.setMediaDiscoverAdapterNew(this);
        return new ItemViewHolder(inspirationItemsBinding);
    }

Cheers!
