从Firebase加载数据时，RecyclerView onBindViewHolder（）错误

Question

我在Firebase上拥有数据，我正在尝试使用自定义布局文件将其读入RecyclerView。我不知道代码出了什么问题。（手动添加数据）

我正在将约束布局用于自定义布局文件。

读取/写入权限为真，并且还应用了SHA1密钥。

这与布局有关吗？

activity_shop具有约束布局，在其中添加了固定大小的回收站视图，然后创建了具有约束布局的自定义布局文件。

这是我的ShopActivity.java代码。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_shop);
    recyclerView = findViewById(R.id.my_Rv);

    final LinearLayoutManager layoutManager = new LinearLayoutManager(ShopActivity.this);
    recyclerView.setLayoutManager(layoutManager);

    DataRef = FirebaseDatabase.getInstance().getReference().child("Products");

    DataRef.keepSynced(true);
    LoadData();
}

这是我的LoadData（）方法。

private void LoadData() {
        options = new FirebaseRecyclerOptions.Builder<Products>().setQuery(DataRef,Products.class).build();
        adapter = new FirebaseRecyclerAdapter<Products, MyViewHolder>(options) {

            @Override
            protected void onBindViewHolder(@NonNull MyViewHolder holder, int position, @NonNull Products model) {
                holder.product.setText(model.getName());
                holder.net.setText(model.getNetweight());
                holder.price.setText(model.getPrice());
                Picasso.with(getApplicationContext()).load(model.getImage()).into(holder.imageView);


            }

            @NonNull
            @Override
            public MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
                View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.blog_row,parent, false);
                return new MyViewHolder(v);
            }
        };
        adapter.startListening();
        recyclerView.setAdapter(adapter);
    }

这是我的自定义布局文件。

这是正在膨胀的blog_row.xml文件。

Answer 1

在onBindViewHolder中，您拥有：

holder.product.setText(model.getName());
holder.net.setText(model.getNetweight());
holder.price.setText(model.getPrice());

似乎model.getX()中的一个（根据堆栈跟踪，在第47行中的一个返回一个整数，然后您的文本视图尝试将其解析为字符串资源，从而导致异常。

您需要将其转换为String。
