I have a RecyclerView with a fixed height inside a NestedScrollView with a few other layouts inside it. The recycler view won't scroll, but it scrolls fine if I set its height to wrap_content.
I cannot make the RecyclerView use wrap_content because there is an issue with EndlessRecyclerViewScrollListener that it keeps loading data from the server and pushing it into my Adapter even if the user has not scrolled down at all.
Most are suggesting to set nested scrolling to false, but if I disable nested scrolling, the NestedScrollView does not allow me to scroll my RecyclerView. But if I leave nested scrolling enabled, the scroll view does not scroll unless I start touching from outside the RecyclerView.
My layout code:

What do I have to modify so that the RecyclerView is scrollable, but the whole NestedScrollView also scrolls along with it, so that if the user is scrolling back up (swiping from top to bottom), the RecyclerView will scroll along with the NestedScrollView, which will bring the layouts above RecyclerView.
To visualize:
The layout I'm trying to achieve is similar to that of facebook's. When you scroll down, the timeline will scroll down, and the search bar with the messenger icon at the top is also scrolled so that it is hidden when scrolling down. When you scroll up, the timeline is being scrolled back up, and showing the search bar again.
