FriendsFragment.class

public class FriendsFragment extends Fragment{

    private static final String TAG = "FriendsFragment";

    public FriendsFragment() {
    }

    FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
    CollectionReference friends = FirebaseFirestore.getInstance().collection("Users").document(user.getUid()).collection("friends");

    RecyclerView recyclerView;


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

        Log.d(TAG, "onCreateView: "+ friends);
        final Query query = friends.limit(2);
        recyclerView = view.findViewById(R.id.id_recycleViewFriends);
        recyclerView.setLayoutManager(new LinearLayoutManager(getApplicationContext()));

        FirestoreRecyclerOptions<FriendModel> options = new FirestoreRecyclerOptions.Builder<FriendModel>()
                .setQuery(query,FriendModel.class)
                .setLifecycleOwner(this)
                .build();

        FirestoreRecyclerAdapter<FriendModel,FriendHolder> adapter = new FirestoreRecyclerAdapter<FriendModel, FriendHolder>(options) {
            @Override
            protected void onBindViewHolder(FriendHolder holder, int position, FriendModel model) {
                   holder.setName(model.getName());
            }

            @Override
            public FriendHolder onCreateViewHolder(ViewGroup parent, int viewType) {
                return new FriendHolder(LayoutInflater.from(parent.getContext())
                        .inflate(R.layout.single_friend_row_test,parent,false));
            }
        };
        recyclerView.setAdapter(adapter);
        return view;
    }
}

FriendModel.class

public class FriendModel
     {
        private String name;


        public FriendModel() {
        }


        public FriendModel(String name) {
            this.name = name;
        }

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

    }

FriendHolder.class

public class FriendHolder extends RecyclerView.ViewHolder {

    private TextView name;

    public FriendHolder(View itemView) {
        super(itemView);
        name = itemView.findViewById(R.id.id_name);
    }

    public void setName(String sName) {
      name.setText(sName);
    }

}

我找到了解决方案，问题在于

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

应该{{1}}作为参数而不是getActivity() 虽然问题已经解决，但如果有人知道为什么会这样运作，我将非常感激。
