Question

我在网上关注了一个教程。我把所有这些代码都放在了我的onCreate

之前

IabHelper.OnConsumeFinishedListener mConsumeFinishedListener =
        new IabHelper.OnConsumeFinishedListener() {
            public void onConsumeFinished(Purchase purchase,
                                          IabResult result) {

                if (result.isSuccess()) {
                        btnPurchase.setEnabled(false);
                    btnStats.setBackgroundResource(R.drawable.purchasepressed);
                    test.setText("IT WORKS!!!");

                } else {
                    // handle error
                }
            }
        };
public void consumeItem() throws IabHelper.IabAsyncInProgressException {
    mHelper.queryInventoryAsync(mReceivedInventoryListener);

}




@Override
protected void onActivityResult(int requestCode, int resultCode,
                                Intent data) {
    try {
        if (!mHelper.handleActivityResult(requestCode,
                resultCode, data)) {
            super.onActivityResult(requestCode, resultCode, data);
        }
    } catch (IabHelper.IabAsyncInProgressException e) {
        e.printStackTrace();
    }
}




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


        if (result.isFailure()) {
            // Handle failure
        } else {
            mHelper.consumeAsync(inventory.getPurchase(ITEM_SKU), mConsumeFinishedListener);
        }
    }
};


public void buyClick(View view) throws IabHelper.IabAsyncInProgressException {


 mHelper.launchPurchaseFlow(this, ITEM_SKU, 10001,
            mPurchaseFinishedListener, "mypurchasetoken");
}

IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener
        = new IabHelper.OnIabPurchaseFinishedListener() {
    public void onIabPurchaseFinished(IabResult result,
                                      Purchase purchase) throws IabHelper.IabAsyncInProgressException {
        if (result.isFailure()) {
            // Handle error
            return;
        } else if (purchase.getSku().equals(ITEM_SKU)) {

            btnPurchase.setEnabled(false);
            btnPurchase.setBackgroundResource(R.drawable.purchasepressed);
            test.setText("IT WORKS!!!");


        }

    }
};

我的印象是购买后.getSKU（）。equals（ITEM_SKU）如果购买成功，你可以放置任何应该执行的代码。

正如您在此处所见，如果购买成功，我的购买按钮应被禁用并更改其背景图像。我还添加了一个测试文本标签，以查看错误是否在我的代码中的其他位置。

当我在手机上运行代码时，我会看到购买对话框并取得成功，但按钮和文字不会改变。

请帮忙。

为什么我的消耗品不起作用？
