如何在片段中使用onActivityResult（）？

Question

在我的应用程序中，我想使用InAppBillling购买一些功能！
我将付款方式写入fragment但是在显示付款dialog并由用户付款之后，我没有向onActivityResult显示任何数据！
我将log.e写入onActivityResult ，但再次未显示。
我认为不参加onActivityResult ！

我的片段代码：

public class ServicesFragment extends BaseFragment implements IabHelper.OnIabSetupFinishedListener,
        IabHelper.QueryInventoryFinishedListener, IabHelper.OnIabPurchaseFinishedListener, IabHelper.OnConsumeFinishedListener {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_services, container, false);

...

}

    @Override
    public void onIabSetupFinished(IabResult result) {
        if (iabHelper != null) {
            iabHelper.flagEndAsync();
            //This is call for payment
            iabHelper.queryInventoryAsync(ServicesFragment.this);
        }
    }

    @Override
    public void onIabPurchaseFinished(IabResult result, final Purchase info) {
        //After payment call this
        if (result.isSuccess() && info != null) {
            handler.post(new Runnable() {
                @Override
                public void run() {
                    getCheckBuyFromBazaar(jwtToken, packageName, productId, purchaseToken, buyID, 0, info);
                }
            });
        }
    }

    @Override
    public void onQueryInventoryFinished(IabResult result, Inventory inv) {
        if (result.isSuccess()) {
            bazaarProgressDialog.dismiss();
            //Run bazaar dialog
            if (iabHelper != null) {
                iabHelper.flagEndAsync();
                iabHelper.launchPurchaseFlow(activity, bazaarSKU, bazaarRequestCode,
                        ServicesFragment.this, bazaarHashCode);
            }
        }
    }

    @Override
    public void onConsumeFinished(Purchase purchase, IabResult result) {
        if (result.isSuccess() && purchase != null) {
            if (purchase.getSku().equalsIgnoreCase(bazaarSKU)) {
                //When purchase consumed
                finishPage();
                loadingProgressDialog.dismiss();
            }
        }
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        Log.e("BazaarPaymentLog", "Result");
        if (iabHelper == null) return;

        if (requestCode == bazaarRequestCode) {
            String purchaseData = data.getStringExtra("INAPP_PURCHASE_DATA");
            if (resultCode == RESULT_OK) {
                try {
                    JSONObject jo = new JSONObject(purchaseData);
                    purchaseToken = jo.getString("purchaseToken");
                    productId = jo.getString("productId");
                    packageName = jo.getString("packageName");

                    Log.e("BazaarPaymentLog", "purchaseToken : " + purchaseToken);
                    if (iabHelper != null) {
                        iabHelper.handleActivityResult(requestCode, resultCode, data);
                    }
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
        } else {
            super.onActivityResult(requestCode, resultCode, data);
        }
    }

}

显示付款对话框，然后我付款，但是不转到onActivityResult ！

我将上面的代码写到activity 就可以了，然后运行onActivityResult但是fragment不会进入onActivityResult ！

我该如何解决？

实际上，将结果传递给Activity的onActivtyResult以便获得Fragment的方法，您需要将reult fron Activity传递给Fragment，如下所示

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.frame);
    fragment.onActivityResult(requestCode, resultCode, data);
}

并在Fragment中调用它与您当前正在调用的相同

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

}

如果您使用的是ViewPager，则可以获取如下片段

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        Fragment mFragment = myPagerAdapter.getItem(mViewPager.getCurrentItem());
        if (fragment instanceof ServiccesFragment){
            ((ServiccesFragment)fragment).onActivityResult(requestCode, resultCode, data);
        }

    }
