如何通过应用内购买购买 recyclerview 中的每件商品

Question

我正在尝试为我的应用添加应用内购买。问题是我需要为 recyclerview 中的每个项目购买。

private RecyclerView recyclerView;

//Billing
private BillingClient billingClient;
private List skuList = new ArrayList();
private String sku = "sk_peoplesio_new_connection";
SkuDetails skuDetails ;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_freelancer_order);

    Button button = findViewById(R.id.freelancer_purchased_order_btn);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            startActivity(new Intent(FreelancerOrderActivity.this,FreelancerPurchasedOrderActivity.class));
        }
    });
    recyclerView = findViewById(R.id.freelancer_order_list);
    recyclerView.setHasFixedSize(false);
    LinearLayoutManager layoutManager = new LinearLayoutManager(this);
    layoutManager.setReverseLayout(true);
    layoutManager.setStackFromEnd(true);
    recyclerView.setLayoutManager(layoutManager);

    Toast.makeText(this, "Long press on the item to view their request's...!", Toast.LENGTH_LONG).show();


    //Billing
    skuList.add(sku);

    setupBillingClient();
}


@Override
protected void onStart() {
    super.onStart();

    final DatabaseReference reference = FirebaseDatabase.getInstance().getReference().child("FreelancerOrders").child(Freevalent.currentOnlineFreelancer.getPhone());

    FirebaseRecyclerOptions<ClientOrders> options =
            new FirebaseRecyclerOptions.Builder<ClientOrders>()
                    .setQuery(reference,ClientOrders.class)
                    .build();

    FirebaseRecyclerAdapter<ClientOrders, TextViewHolder> adapter =
            new FirebaseRecyclerAdapter<ClientOrders, TextViewHolder>(options) {
                @Override
                protected void onBindViewHolder(@NonNull final TextViewHolder  textViewHolder, int i, @NonNull final ClientOrders requests) {

                    textViewHolder.name.setText("Do you want this order...?" + "\n\n"+"Long press to see the client's  requests's");


                    textViewHolder.itemView.setOnLongClickListener(new View.OnLongClickListener() {
                        @Override
                        public boolean onLongClick(View v) {
                            Intent i = new Intent(FreelancerOrderActivity.this,FreelancerParticularClientActivity.class);
                            i.putExtra("phone",requests.getPhone());
                            startActivity(i);
                            return true;
                        }
                    });

                    textViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View v) {
                            AlertDialog.Builder builder = new AlertDialog.Builder(FreelancerOrderActivity.this);
                            builder.setTitle("Do you want to buy this Connection...?")
                                    .setPositiveButton("Yes", new DialogInterface.OnClickListener() {

}

我关注了this youtube tutorial。我需要为每件商品进行购买，我会在同一频道的其他教程中确认。

我想在购买完成后将 requests.getPhone() 传递给 purchaseSingleClientInfo 方法。

Answer 1

一个应用内商品只能购买一次，用户不能拥有多个相同的商品，如果你想多次购买，你必须先消费。

您似乎想一次购买清单上的所有产品。

应用内计费库不提供同时购买多个产品的任何方法，唯一的方法是通过询问付款方式和其他选项的对话框逐个进行。
