如何使用firebase UI在recyclerView中显示时从Firebase数据库中的子项引用父项

implementation 'com.firebaseui:firebase-ui-database:8.0.0'

FirebaseDatabase database = FirebaseDatabase.getInstance();
DatabaseReference parentRef = database.getReference("父项路径");
DatabaseReference childRef = parentRef.child("子项路径");

FirebaseRecyclerOptions<数据模型类> options = new FirebaseRecyclerOptions.Builder<数据模型类>()
        .setQuery(childRef, 数据模型类.class)
        .build();

FirebaseRecyclerAdapter<数据模型类, ViewHolder类> adapter = new FirebaseRecyclerAdapter<数据模型类, ViewHolder类>(options) {
    @Override
    protected void onBindViewHolder(@NonNull ViewHolder类 holder, int position, @NonNull 数据模型类 model) {
        // 在这里设置ViewHolder中的视图内容
    }

    @NonNull
    @Override
    public ViewHolder类 onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        // 创建ViewHolder并返回
    }
};

recyclerView.setAdapter(adapter);
recyclerView.setLayoutManager(new LinearLayoutManager(this));

adapter.startListening();
