我如何解决，E / RecyclerView：未连接适配器；跳过布局？

Question

我不断得到

  

E/RecyclerView: No adapter attached; skipping layout

  View rooView=inflater.inflate( R.layout.fragment_users , container, false );
        mUsers=new ArrayList<>(  );
        readUsers();
        recyclerView=(RecyclerView) rooView.findViewById( R.id.recycler_View );
        recyclerView.setHasFixedSize( true );
        recyclerView.setLayoutManager( new LinearLayoutManager( getContext() ) );
        return rooView;
