解决E / RecyclerView问题：未连接适配器；在应用打开期间跳过布局。

private RecyclerView recyclerView;

private UserAdapter userAdapter;
private List<User> mUsers;

FirebaseUser fuser;
DatabaseReference reference;

private List<Chatlist> usersList;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_chats, container, false);

    recyclerView = view.findViewById(R.id.recycler_view);
    recyclerView.setHasFixedSize(true);
    recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));

    fuser = FirebaseAuth.getInstance().getCurrentUser();

请帮助

您似乎在文件顶部声明了一个适配器，但是我看不到您是在适配器上设置数据源，然后在回收站上设置适配器，如下所示：

userAdapter = new UserAdapter(mUsers);
recyclerView.setAdapter(userAdapter);

还，您编写了完整的UserAdapter吗？

Google提供了一些出色的文档，其中包含有关如何实现Recyclerview的示例： https://developer.android.com/guide/topics/ui/layout/recyclerview
