FirestoreRecyclerAdapter 没有虚拟方法 getDocument

Question

我目前正在将我的 Firebase UI 组件转换为 Firestore UI 组件。在构建 FirestoreRecyclerAdapter 并手动调用 adapter.startListening() 或通过 new FirestoreRecyclerOptions.Builder().setLifeCycleOwner() 初始化它时，我偶然发现了以下致命异常。

FATAL EXCEPTION: main

错误指出 class DocumentSnapshot 不包含经检查正确的方法 getDocument。然而，这也是 FirebaseUI 在他们的文档中描述这个实现的方式，我不知道我哪里做错了。

回收商使用的查询 Query query = mFirestore.collection("spots");，集合存在，并且包含 documents。

带查询的适配器

mRecyclerView = (RecyclerView) view;
            mRecyclerView.setLayoutManager(new LinearLayoutManager(context));

            Query query = mFirestore.collection("spots");
            FirestoreRecyclerOptions<SpotModel> options = new FirestoreRecyclerOptions.Builder<SpotModel>().setQuery(query, SpotModel.class).setLifecycleOwner(this).build();

            mAdapter = new FirestoreRecyclerAdapter<SpotModel, SpotHolder>(options) {
                @Override
                public SpotHolder onCreateViewHolder(ViewGroup parent, int viewType) {
                    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_spot, parent, false);

                    return new SpotHolder(view);
                }

                @Override
                protected void onBindViewHolder(@NonNull SpotHolder holder, int position, @NonNull SpotModel model) {
                    holder.bind(model);
                }
            };

            mRecyclerView.setAdapter(mAdapter);

FirebaseUI 依赖项

implementation 'com.firebaseui:firebase-ui-auth:3.2.2'
implementation 'com.firebaseui:firebase-ui-database:3.2.2'
implementation 'com.firebaseui:firebase-ui-firestore:3.2.2'

正在片段的 onCreateView 方法中初始化适配器。我按照 FirebaseUI 的 Github 页面上的说明进行操作，但没有成功 (link)

请尽量不要加倍post。

对于其他所有人：这是一个 known issue，将在与 Play Services 12.0.1 配对的 FUI 3.3.0 中修复。目前，降级到 Play Services 11.8.0 即可。
