                android:scrollbars="vertical"
                android:id="@+id/recyclerView"
                />

In Fragment you must use getActivity() or getContext(). [for details refer this link.](https://stackoverflow.com/questions/8215308/using-context-in-a-fragment) — vignesh, Oct 22 '19 at 06:45

Try this,

RecyclerView recyclerView = root.findViewById(R.id.recyclerView); 
RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getActivity());
Rcv_Results.setLayoutManager(mLayoutManager);

You have to use 

recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));

instead of

recyclerView.setLayoutManager(new LinearLayoutManager(this));
