Android应用内结算 - 如何多次购买单个应用内购买？

Question

我该如何多次购买一件东西？这里是我的代码：

// [...] 
    String base64EncodedPublicKey = 
       "MIIB...; 

     mHelper = new IabHelper(this, base64EncodedPublicKey); 

     mHelper.startSetup(new 
            IabHelper.OnIabSetupFinishedListener() { 
             public void onIabSetupFinished(IabResult result) { 
              if (!result.isSuccess()) { 
               Toast.makeText(gift.this, "Setup no Success", Toast.LENGTH_SHORT).show(); 
               Log.d(TAG, "In-app Billing setup failed: " + result); 
              } else { 
               Toast.makeText(gift.this, "Setup Success", Toast.LENGTH_SHORT).show(); 
              } 
             } 
            }); 


    } 


    public void insert(View view) { 
     mHelper.launchPurchaseFlow(this, ITEM_SKU, 10001, 
       mPurchaseFinishedListener, "mypurchasetoken"); 
    } 

    @Override 
    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()) { 
       Toast.makeText(gift.this, "Error 1", Toast.LENGTH_SHORT).show(); 
      } 
      else if (purchase.getSku().equals(ITEM_SKU)) { 
       consumeItem(); 
       Toast.makeText(gift.this, "OK 1", Toast.LENGTH_SHORT).show(); 
       // mHelper.consumeAsync(purchase, mConsumeFinishedListener); 
      } 

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

    IabHelper.QueryInventoryFinishedListener mReceivedInventoryListener 
      = new IabHelper.QueryInventoryFinishedListener() { 
     public void onQueryInventoryFinished(IabResult result, 
              Inventory inventory) { 

      if (result.isFailure()) { 
       Toast.makeText(gift.this, "Error 2", Toast.LENGTH_SHORT).show(); 
      } else { 
       mHelper.consumeAsync(inventory.getPurchase(ITEM_SKU), 
         mConsumeFinishedListener); 
       Toast.makeText(gift.this, "OK 2", Toast.LENGTH_SHORT).show(); 
      } 
     } 
    }; 
    IabHelper.OnConsumeFinishedListener mConsumeFinishedListener = 
      new IabHelper.OnConsumeFinishedListener() { 
       public void onConsumeFinished(Purchase purchase, 
               IabResult result) { 

        if (result.isSuccess()) { 
         Toast.makeText(gift.this, "Success 1", Toast.LENGTH_SHORT).show(); 
         // mHelper.consumeAsync(purchase, mConsumeFinishedListener); 
        } else { 
         Toast.makeText(gift.this, "Error 3", Toast.LENGTH_SHORT).show(); 
        } 
       } 
      }; 

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

当我在我的按钮，点击它说：“支付成功”之后，当我点击我的按钮，再不会做任何事情。

我有2个问题：

1. 如何购买一个应用程序内购买多次吗？
2. 如何在支付成功后显示Toast？

感谢您的回答。

Answer 1

1. 购买必须在每次购买后消耗，然后可以再次购买。如果您能够购买一次，但不能再次购买，那么几乎可以肯定的是，问题在于您没有正确使用它。

2. 你的代码似乎没有任何问题，Toast.makeText（...）应该可以正常工作。
