【问题描述】：
我正在学习为我的应用实施应用内结算，例如，人们可以在按下捐赠按钮时捐赠 $。
允许用户多次捐赠，即购买为消耗品。
以下代码来自 TrivalDrive 示例和网络上的一些教程：
代码：
IabHelper mHelper;
static final String ITEM_SKU = "android.test.purchased";
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_in_app_billing);
buy10Button = (Button) findViewById(R.id.buy10Button);
buy15Button = (Button) findViewById(R.id.buy15Button);
buy20Button = (Button) findViewById(R.id.buy20Button);
String base64EncodedPublicKey = "keykeykey";
mHelper = new IabHelper(this, base64EncodedPublicKey);
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener()
{
public void onIabSetupFinished(IabResult result)
{
if (!result.isSuccess())
{
Log.d(TAG, "In-app Billing setup failed: " + result);
return;
}
if (mHelper == null)
{
return;
}
Log.d(TAG, "In-app Billing is set up OK");
}
});
}
public void buy10Click(View view)
{
mHelper.launchPurchaseFlow(this, ITEM_SKU, 10001, mPurchaseFinishedListener, "");
}
public void buy15Click(View view)
{
}
public void buy20Click(View view)
{
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (mHelper == null) return;
if (!mHelper.handleActivityResult(requestCode, resultCode, data))
{
super.onActivityResult(requestCode, resultCode, data);
}
}
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener()
{
public void onIabPurchaseFinished(IabResult result, Purchase purchase)
{
if (mHelper == null) return;
if (result.isFailure())
{
// Handle error
return;
}
else if ((purchase.getSku().equals(ITEM_SKU)))
{
consumeItem();
}
}
};
public void consumeItem()
{
mHelper.queryInventoryAsync(mReceivedInventoryListener);
}
IabHelper.QueryInventoryFinishedListener mReceivedInventoryListener = new IabHelper.QueryInventoryFinishedListener()
{
public void onQueryInventoryFinished(IabResult result, Inventory inventory)
{
if (mHelper == null) return;
if (result.isFailure())
{
// Handle failure
}
else
{
mHelper.consumeAsync(inventory.getPurchase(ITEM_SKU), mConsumeFinishedListener);
}
}
};
IabHelper.OnConsumeFinishedListener mConsumeFinishedListener = new IabHelper.OnConsumeFinishedListener()
{
public void onConsumeFinished(Purchase purchase, IabResult result)
{
if (mHelper == null) return;
if (result.isSuccess())
{
Toast.makeText(InAppBillingActivity.this, "Thank you for your donation!!", Toast.LENGTH_LONG).show();
}
else
{
// handle error
}
}
};
问题：
但我不断收到E/IabHelper(13392): In-app billing error: Unable to buy item, Error response: 7:Item Already Owned 错误，而且 Google Play 的付款对话框没有弹出。
我研究了很多类似的情况，有的建议等几分钟，然后购买会自动重置，但我等了快一个小时，但还是很糟糕。
我还发现有人建议更改 IabResult public boolean isSuccess() { return mResponse == IabHelper.BILLING_RESPONSE_RESULT_OK; } 以将 BILLING_RESPONSE_RESULT_ITEM_ALREADY_OWNED 也返回为 isSuccess = true，但我不知道如何修改此类...
如何解决问题？谢谢！！

确保在启动时获取库存以检查是否拥有任何物品，如果有则消耗它。
