推荐答案

要解决此问题，请使用以下代码:

To solve this, please use the following code:

FirebaseRecyclerOptions<RecycleModel> firebaseRecyclerOptions = new FirebaseRecyclerOptions.Builder<RecycleModel>()
    .setQuery(muserDB, RecycleModel.class)
    .build();

recyclerViewadapter=new FirebaseRecyclerAdapter<RecycleModel, UserViewHolder>(firebaseRecyclerOptions) {
    @Override
    protected void onBindViewHolder(@NonNull UserViewHolder holder, int position, @NonNull RecycleModel model) {
            // set the model to the holder
    }

    @NonNull
    @Override
    public UserViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        return null;
    }
};

FirebaseRecyclerAdapter类在构造器中将最后一个版本的参数作为FirebaseRecyclerOptions对象的参数，而不再是这四个参数.

FirebaseRecyclerAdapter class takes in the last version as an argument in the constructor a FirebaseRecyclerOptions object not those 4 arguments anymore.

如果您有兴趣，请是推荐的方法，您可以从Firebase Realtime数据库中检索数据，并使用FirebaseRecyclerAdapter在RecyclerView中将其显示.

If you are interested, this is a recommended way in which you can retrieve data from a Firebase Realtime database and display it in a RecyclerView using FirebaseRecyclerAdapter.
