我正在开发一个应用程序，该应用程序的需求是需要在线支付。
我想用印度货币（卢比）从我的申请中向店主支付账单金额。我尝试了一个使用 MPL 的演示示例。
我创建了一个类：
public class MainActivity extends Activity implements OnClickListener {
private boolean _paypalLibraryInit = false;
final static public int PAYPAL_BUTTON_ID = 10001;
CheckoutButton launchPayPalButton;
public static String resultTitle;
public static String resultInfo;
public static String resultExtra;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initLibrary();
if (_paypalLibraryInit) {
showPayPalButton();
} else {
finish();
}
}
/** init method **/
public void initLibrary() {
PayPal pp = PayPal.getInstance();
if (pp == null) {
// This is the main initialization call that takes in your Context,
// the Application ID, and the server you would like to connect to.
pp = PayPal.initWithAppID(this, "APP-80W284485P519543T",PayPal.ENV_SANDBOX);
// -- These are required settings.
pp.setLanguage("en_US"); // Sets the language for the library.
// --
// -- These are a few of the optional settings.
// Sets the fees payer. If there are fees for the transaction, this
// person will pay for them. Possible values are FEEPAYER_SENDER,
// FEEPAYER_PRIMARYRECEIVER, FEEPAYER_EACHRECEIVER, and
// FEEPAYER_SECONDARYONLY.
pp.setFeesPayer(PayPal.FEEPAYER_EACHRECEIVER);
// Set to true if the transaction will require shipping.
pp.setShippingEnabled(true);
// Dynamic Amount Calculation allows you to set tax and shipping
// amounts based on the user's shipping address. Shipping must be
// enabled for Dynamic Amount Calculation. This also requires you to
// create a class that implements PaymentAdjuster and Serializable.
pp.setDynamicAmountCalculationEnabled(false);
// --
_paypalLibraryInit = true;
}
}
private void showPayPalButton() {
// Generate the PayPal checkout button and save it for later use
PayPal pp = PayPal.getInstance();
launchPayPalButton = pp.getCheckoutButton(this, PayPal.BUTTON_278x43,CheckoutButton.TEXT_PAY);
// Add the listener to the layout
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
params.bottomMargin = 10;
params.leftMargin= 50;
launchPayPalButton.setLayoutParams(params);
launchPayPalButton.setId(PAYPAL_BUTTON_ID);
// The OnClick listener for the checkout button
launchPayPalButton.setOnClickListener(this);
//((RelativeLayout) findViewById(R.id.RelativeLayout01)).addView(launchPayPalButton);
((RelativeLayout) findViewById(R.id.rl)).addView(launchPayPalButton);
}
@Override
public void onClick(View v) {
// Use our helper function to create the simple payment.
PayPalButtonClick(v);
// Use checkout to create our Intent.
// Intent checkoutIntent = PayPal.getInstance().checkout(payment, this,
// new ResultDelegate());
// Use the android's startActivityForResult() and pass in our Intent.
// This will start the library.
// startActivityForResult(checkoutIntent, request);
}
public void PayPalButtonClick(View arg0) {
// Create a basic PayPal payment
PayPalPayment payment = new PayPalPayment();
// Set the currency type
payment.setCurrencyType("USD");
// Set the recipient for the payment (can be a phone number)
payment.setRecipient("abc@gmail.com");
// Set the payment amount, excluding tax and shipping costs
payment.setSubtotal(new BigDecimal("1.0"));
// Set the payment type--his can be PAYMENT_TYPE_GOODS,
// PAYMENT_TYPE_SERVICE, PAYMENT_TYPE_PERSONAL, or PAYMENT_TYPE_NONE
payment.setPaymentType(PayPal.PAYMENT_TYPE_GOODS);
// PayPalInvoiceData can contain tax and shipping amounts, and an
// ArrayList of PayPalInvoiceItem that you can fill out.
// These are not required for any transaction.
PayPalInvoiceData invoice = new PayPalInvoiceData();
// Set the tax amount
invoice.setTax(new BigDecimal("0"));
Intent checkoutIntent = PayPal.getInstance().checkout(payment, this /*, new ResultDelegate()*/);
this.startActivityForResult(checkoutIntent, 1);
}
public void PayPalActivityResult(int requestCode, int resultCode, Intent intent) {
if(requestCode != 1)
return;
Toast.makeText(getApplicationContext(),resultTitle , Toast.LENGTH_SHORT).show();
}
}
结果委托类为：
public class ResultDelegate implements PayPalResultDelegate, Serializable {
private static final long serialVersionUID = 10001L;
/**
* Notification that the payment has been completed successfully.
*
* @param payKey the pay key for the payment
* @param paymentStatus the status of the transaction
*/
public void onPaymentSucceeded(String payKey, String paymentStatus) {
MainActivity.resultTitle = "SUCCESS";
MainActivity.resultInfo = "You have successfully completed your transaction.";
MainActivity.resultExtra = "Key: " + payKey;
}
/**
* Notification that the payment has failed.
*
* @param paymentStatus the status of the transaction
* @param correlationID the correlationID for the transaction failure
* @param payKey the pay key for the payment
* @param errorID the ID of the error that occurred
* @param errorMessage the error message for the error that occurred
*/
public void onPaymentFailed(String paymentStatus, String correlationID,
String payKey, String errorID, String errorMessage) {
MainActivity.resultTitle = "FAILURE";
MainActivity.resultInfo = errorMessage;
MainActivity.resultExtra = "Error ID: " + errorID + "\nCorrelation ID: "
+ correlationID + "\nPay Key: " + payKey;
}
/**
* Notification that the payment was canceled.
*
* @param paymentStatus the status of the transaction
*/
public void onPaymentCanceled(String paymentStatus) {
MainActivity.resultTitle = "CANCELED";
MainActivity.resultInfo = "The transaction has been cancelled.";
MainActivity.resultExtra = "";
}
}
还下载了 Paypal_MPL.jar 文件并在应用程序中导入并创建了一个 paypal 个人帐户。
1.现在的问题是如何测试应用程序？
2. 我在正确的轨道上吗？
3. 我还需要做什么？
我不清楚 MPL 的实施步骤以及如何在 Paypal 上创建帐户、测试帐户、将帐户链接到应用程序等。
请建议我并指导我。
