回收器视图或Firebase收集查询的问题

Question

我被困在将数据获取到回收器视图上，我不知道问题到底在哪里 如果它来自firebase查询或设置回收器视图的适配器，则回收库会创建燃烧箱中存在的项目的确切数字，但是，没有任何信息显示这是我尝试的

firebase

fun GetProductsList (fragment : Fragment) {
        var productList: ArrayList<Products> = ArrayList()
        mFireStore.collection("products")
            .get()
            .addOnSuccessListener { docSnapshot ->

                for (document in docSnapshot.documents) {
                    val productToAddToList : Products = document.toObject(Products::class.java)!!
                    productList.add(productToAddToList!!)
                }
                when (fragment) {
                    is AdminProductFragment -> {
                        fragment.SuccesProductListFromFireStore(productList)
                    }
                }

适配器

toverride fun onBindViewHolder(holder: RecyclerView.ViewHolder, position: Int) {
            val Model = productsList[position]
        if (holder is MyViewHolder ) {
            GlideLoader(context).loadProductPicture(Model.Image, holder.itemView.iv_item_image)
            holder.itemView.tv_item_name.text = Model.Name.toString()
            holder.itemView.tv_item_price.text = "${Model.Price.toString()} DZA"
        }
    }

，这是我尝试的。

if (productList.size > 0 ) {
            recyclerViewProduct.visibility = View.VISIBLE
            text_no_productFounds.visibility = View.GONE
            recyclerViewProduct.layoutManager = LinearLayoutManager(activity)
            recyclerViewProduct.setHasFixedSize(true)
            val adapterProduct = MyProductsListAdapter(requireActivity(), productList)
            recyclerViewProduct.adapter = adapterProduct
        }else{
            recyclerViewProduct.visibility = View.GONE
            text_no_productFounds.visibility = View.VISIBLE
        }
