FirebaseRecyclerAdapter是否添加hasChild()方法？

FirebaseRecyclerAdapter adapter = new FirebaseRecyclerAdapter<YourModel, YourViewHolder>(options) {
    @Override
    protected void onBindViewHolder(@NonNull YourViewHolder holder, int position, @NonNull YourModel model) {
        // 绑定数据到ViewHolder
    }

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

// 获取指定位置的数据模型对象
YourModel model = adapter.getItem(position);

// 获取指定路径的引用
DatabaseReference reference = FirebaseDatabase.getInstance().getReference("yourPath");

// 判断指定路径下是否存在子节点
boolean hasChild = reference.hasChild("yourChildPath");
