Question

我正在设置带有产品列表的recyclerview，当我向上/向下滚动时，其中的某些项会更改其内容。

我已经调试了我的代码，但是产品列表没有更改。它仅出现在此回收站视图中。

我的问题在这里是视觉的。

这是适配器代码

@Override
public ProductViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {

    productItemBinding = DataBindingUtil.inflate(inflater, R.layout.product_item, parent, false);
    return new ProductViewHolder(productItemBinding);
}

@Override
public void onBindViewHolder(@NonNull ProductViewHolder holder, int position) {
    Product product = mProductList.get(position);
    holder.bindHolder(product);
}



public void setData(List<Product> productList) {

    mProductList = productList;
    notifyDataSetChanged();
}

class ProductViewHolder extends RecyclerView.ViewHolder {

    ProductViewHolder(@NonNull ProductItemBinding productItemBinding) {
        super(productItemBinding.getRoot());
    }

    void bindHolder(Product product) {
        productItemBinding.setProducts(product);
        productItemBinding.setAdapter(ProductAdapter.this);
        productItemBinding.executePendingBindings();
    }
}

这是我给适配器的电话

    productViewModel.getActionProducts("sale", parameter).observe(this, productsContainer -> {

        productsArrayList = new ArrayList<>();
        productsArrayList = actionProductsContainer.getData().getProducts();

        activityProductListingBinding.rvProducts.setLayoutManager(new GridLayoutManager(this, 2));

        productsAdapter = new ProductsAdapter(this, this);
        activityProductListingBinding.rvProducts.setAdapter(productsAdapter);
        productsAdapter.setData(productsArrayList);

        activityProductListingBinding.pbLoadingActionProducts.setVisibility(View.GONE);
    });

这是我用于recyclerview的XML。

            tools:text="@tools:sample/us_zipcodes" />

    </LinearLayout>
</androidx.constraintlayout.widget.ConstraintLayout>

这是自定义绑定以加载图像

@BindingAdapter("setProductImage")
public static void setImageFromServer(ImageView imageView, String imageName) {

    String imageSrc = PRODUCT_STORAGE_BASE_URL.concat(imageName);
    Glide
            .with(imageView.getContext())
            .load(imageSrc)
            .placeholder(R.drawable.place_holder)
            .fitCenter()
            .apply(RequestOptions.centerInsideTransform())
            .diskCacheStrategy(DiskCacheStrategy.AUTOMATIC)
            .into(imageView);
}

一些项目更改了它在recyclerview中的内容
