Android Studio获取购买的计费项目的参考

Question

如何获取用户使用Google结算购买的产品/商品的参考信息？然后还可以参考商品说明

包含付款部分的活动

public class ponerDineroActivity extends AppCompatActivity implements PurchasesUpdatedListener {

产品适配器类

public class MyProductAdapter extends RecyclerView.Adapter<MyProductAdapter.MyViewHolder> {

    ponerDineroActivity ponerDineroActivity;
    List<SkuDetails>  skuDetailsList;
    BillingClient billingClient;

    public MyProductAdapter(com.aplicacion.vivaluganoapp.ar.ponerDineroActivity ponerDineroActivity, List<SkuDetails> skuDetailsList, BillingClient billingClient) {
        this.ponerDineroActivity = ponerDineroActivity;
        this.skuDetailsList = skuDetailsList;
        this.billingClient = billingClient;
    }

    @NonNull
    @Override
    public MyViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
        View itemView = LayoutInflater.from(ponerDineroActivity.getBaseContext())
                .inflate(R.layout.layout_product_item, viewGroup, false);
        return new MyViewHolder(itemView);
    }

    @Override
    public void onBindViewHolder(@NonNull MyViewHolder myViewHolder, final int i) {
        myViewHolder.txt_product.setText(skuDetailsList.get(i).getTitle());

        //Product Click
        myViewHolder.setiProductClickListener(new IProductClickListener() {
            @Override
            public void onProductClickListener(View view, int position) {
                //Launch Billing  follow
                BillingFlowParams billingFlowParams = BillingFlowParams.newBuilder()
                        .setSkuDetails(skuDetailsList.get(i))
                        .build();
                billingClient.launchBillingFlow(ponerDineroActivity,billingFlowParams);
            }
        });
    }

    @Override
    public int getItemCount() {
        return skuDetailsList.size();
    }

    public class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

        TextView txt_product;

        IProductClickListener iProductClickListener;

        public void setiProductClickListener(IProductClickListener iProductClickListener) {
            this.iProductClickListener = iProductClickListener;
        }

        public MyViewHolder(@NonNull View itemView) {
            super(itemView);
            txt_product = (TextView) itemView.findViewById(R.id.txt_product_name);

            itemView.setOnClickListener(this);
        }

        @Override
        public void onClick(View v) {
            iProductClickListener.onProductClickListener(v,getAdapterPosition());
        }
    }
}

我需要的是能够识别用户购买了哪些产品/商品，然后获取产品说明，并将其添加到用户的当前积分（currentusermoney）中
