firestoreRecyclerAdapter无虚拟方法getDocument

Question

我当前正在将firebase UI组件转换为firestore UI组件。构建FirestoreRecyclerAdapter并手动致电adapter.startListening()或通过new FirestoreRecyclerOptions.Builder().setLifeCycleOwner()初始化它时，我偶然发现了以下致命例外。

错误指出类DocumentSnapshot不包含方法getDocument，该方法在检查后正确。但是，这也是Firebaseui在其文档中陈述该实现的方式，我无法弄清楚我在哪里做错了什么。

用于回收器的查询 Query query = mFirestore.collection("spots");，该集合存在，并在内部具有documents。

带有查询的适配器

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依赖关系

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'

适配器正在以片段的onCreateView方法初始化。我遵循Firebaseui的GitHub页面上的说明，但没有成功(link(

请尽量不要双重发帖。

对于其他所有人：这是一个已知的问题，将在FUI 3.3.0与Play Services 12.0.1配对。目前，降级到播放服务11.8.0将做到这一点。
