Android应用程序内购买易耗品

问题描述：

问题是，该应用程序不允许用户购买多次。我需要让我的物品消耗，答案全部解释为here。Android应用程序内购买易耗品

我需要知道的是正是我不得不把这个部分：

mHelper.consumeAsync(purchase, mConsumeFinishedListener);

在我的代码？

@Override 
    public void onDestroy() { 
     super.onDestroy(); 
     if (mHelper != null) mHelper.dispose(); 
     mHelper = null; 
    } 

    protected void onActivityResult(int requestCode, int resultCode, 
            Intent data) 
    { 
     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 (result.isFailure()) { 
       // Handle error 
       return; 
      } 
      else if (purchase.getSku().equals(ITEM_SKU)) { 
       consumeItem(); 
       buyButton.setEnabled(false); 
      } 

     } 
    }; 





    public void consumeItem() { 
     mHelper.queryInventoryAsync(mReceivedInventoryListener); 


    } 

    IabHelper.QueryInventoryFinishedListener mReceivedInventoryListener 
      = new IabHelper.QueryInventoryFinishedListener() { 

     public void onQueryInventoryFinished(IabResult result, 
              Inventory inventory) 

     { 

      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 (result.isSuccess()) { 
         clickButton.setEnabled(true); 

        } else { 
         // handle error 
        } 
       } 
      }; 




    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     setContentView(R.layout.activity_in_app_billing); 

     buyButton = (Button)findViewById(R.id.buyButton); 
     clickButton = (Button)findViewById(R.id.clickButton); 



     String base64EncodedPublicKey = 
       "MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA3F8aC2kUFQHf/X3xnfgulD0UpgrQifcjZ66zzhUPhQ/TcrONl22V74Q/Uj57rCwSUfdzz7wbUPxuPayGKBozzoH+2vhMGSetgCFZLcrNbRpBBbihOZrj//GTXMa6VkpUPTAqthEF0oI1M/bW9vF75xZI3u2KAS/AYDfqLTRZ6mh+xh6n/3i0ntSZT+UwzguwyHfS9JwuGGg5AKSutaWhnvOTNeQjsxTskc483h9DfvvRiwdiQPlv7wJRSSIc3RHVwDHleEJ8rsRa8JTypBJuL5oRZSGePUlejWhJvs23tgy5xrvGsMgsICssGzIem2XXSUWm/NDjeO0v2Eh+quQKVQIDAQAB"; 

     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); 
       } else 
       { 
        Log.d(TAG, "In-app Billing is set up OK"); 
       } 
      } 


     }); 

    } 

}

因为在other answer Haxis说：“你要调用刚刚购买后的消费功能。”

任何人都可以帮助我吗？

请不要发布垃圾填充物。解释你的问题，而不是.. –

我有完全相同的问题。但规则说避免“寻求帮助，澄清或回答其他答案”，所以我提出了另一个问题。 – James

答

，你可以在谷歌样品中检查 - https://github.com/googlesamples/android-play-billing/blob/master/TrivialDrive/app/src/main/java/com/example/android/trivialdrivesample/MainActivity.java

consumeAsync（）被调用两次：

- 当购买完成后，在OnIabPurchaseFinishedListener

- 当库存在查询活动的开始，在QueryInventoryFinishedListener

您还需要在购买成功时以及查询库存并查找时调用它（因为如果物品被消耗，那么它不会出现在库存中）
