我在 Android 应用程序中实现了应用程序内结算，有大约 6 种产品，它们就像用户为了在我的应用程序中购买商品而购买的硬币。 应用程序内的设置和测试工作完美我阅读了所有谷歌文档并按照他们说的做了但我的问题是我的产品显示在 ListView 中我根据在 Activity 列表中的位置，但项目总是被消耗或拥有这里是我的代码:

if (mHelper == null) return;
// Is it a failure?
if (result.isFailure()) {
complain("Failed to query inventory: " + result);
return;
}

* a different device, because on the other device you will not have access to the
* random string you originally generated.
*
* So a good developer payload has these characteristics:
*
* 1. If two different users purchase an item, the payload is different between them,
* so that one user's purchase can't be replayed to another user.
*
* 2. The payload must be such that you can verify it even when the app wasn't the
* one who initiated the purchase flow (so that items purchased by the user on
* one device work on other devices owned by the user).
*
* Using your own server to store and verify developer payloads across app
* installations is recommended.

如有任何帮助，我们将不胜感激。
Bank 类:
public class BankClass
{
public int itemID;
public int quantity;
public String price;
public BankClass(int itemID,int quantity,String price)
{
this.itemID=itemID;
this.quantity=quantity;
this.price=price;
}
}
这是我对多消费所做的。
List<Purchase> purchases = new ArrayList<>();
purchases.add(inventory.getPurchase(SKU_hundred));
purchases.add(inventory.getPurchase(SKU_two_hundred_twenty_five));
purchases.add(inventory.getPurchase(SKU_three_hundred_fifty));
purchases.add(inventory.getPurchase(SKU_four_hundred_seventy_five));
purchases.add(inventory.getPurchase(SKU_six_hundred));
purchases.add(inventory.getPurchase(SKU_one_thousand_two_hundred_twenty_five));
IabHelper.OnConsumeMultiFinishedListener onCusumeListner = new IabHelper.OnConsumeMultiFinishedListener()
{
@Override
public void onConsumeMultiFinished(List<Purchase> purchases, List<IabResult> results)
{
Log.d(TAG, "Consumption finished. Purchase: " + purchases + ", result: " + results);
// if we were disposed of in the meantime, quit.
if (mHelper == null) return;
// We know this is the "gas" sku because it's the only one we consume,
// so we don't check which sku was consumed. If you have more than one
// sku, you probably should check...
for(int i=0;i<results.size();i++)
{
if (results.get(i).isSuccess())
{
// successfully consumed, so we apply the effects of the item in our
// game world's logic, which in our case means filling the gas tank a bit
Log.d(TAG, "Consumption successful. Provisioning.");
} else {
complain("Error while consuming: " + results);
}
}
Log.d(TAG, "End consumption flow.");
}
};
mHelper.consumeAsync(purchases, onCusumeListner);
但结果我不知道如何根据那里的位置处理所有项目的结果是否成功，我应该为它运行 for 循环还是有另一种方法，但它仍然在所有方面崩溃。

最佳答案
由于您正在消费多个项目，因此建议通过传递您的购买列表来对多个项目使用 consumeAsync 方法。你可以在里面找到它 TrivialDrive Iab 版本 3 的示例应用程序
/**
* Same as {@link consumeAsync}, but for multiple items at once.
* @param purchases The list of PurchaseInfo objects representing the purchases to consume.
* @param listener The listener to notify when the consumption operation finishes.
*/
public void consumeAsync(List<Purchase> purchases, OnConsumeMultiFinishedListener listener) {
使用 onConsumeMultiFinished 作为回调
public void onConsumeMultiFinished(List<Purchase> purchases, List<IabResult> results);
它应该负责发送适当的异步消费请求。更新您的代码并发布任何问题。
