我正在制作一个计费应用程序，从firestore加载产品数据。我已将属性设置为“活动-非活动”产品。但当我加载所有产品并隐藏非活动产品时，它显示的是空白。


加载gridlayoutmanager的代码：

GridLayoutManager gridLayoutManager = new GridLayoutManager(getApplicationContext(), 2);
    recyclerView.setLayoutManager(gridLayoutManager); // set LayoutManager to RecyclerView
    recyclerView.setHasFixedSize(false);

具有以下条件的适配器：

@Override
public void onBindViewHolder(@NonNull final PosProductAdapter.MyViewHolder holder, int position) {
    String pcode = productData.get(position).getProduct_code();
    String productId = productData.get(position).getProductId();
    firebaseFirestore.collection("products")
            .document(pcode)
            .get()
            .addOnSuccessListener(new OnSuccessListener<DocumentSnapshot>() {
                @Override
                public void onSuccess(DocumentSnapshot documentSnapshot) {
                    if (documentSnapshot.exists())
                    {
                        String s = documentSnapshot.getString("pStatus");
                        Toast.makeText(context, s, Toast.LENGTH_SHORT).show();
                        if (s.equals("inactive"))
                        {
                            holder.pos_product_ll.setVisibility(View.GONE);
                            holder.btnAddToCart.setVisibility(View.GONE);
                        }
                    }
                }
            });
