因为最近项目中需要集成paypal，所以集成了一下，发现网上的有些文章过于老旧，所以自己写一篇踩坑记，首先是去官网申请账号，到时候会分配给你一个client_id
以上准备都做好了 就新建一个项目
- 引入paypel的包
compile('com.paypal.sdk:paypal-android-sdk:2.15.3')
{ exclude group: 'io.card' }// 如果不想支持信用卡支付 就加上这句话
- 新建一个activity 配置
private static PayPalConfiguration config =
new PayPalConfiguration()
.environment(PayPalConfiguration.ENVIRONMENT_SANDBOX)
.clientId("<YOUR_CLIENT_ID>");
这里就输入你的client_id
3.然后在oncreate中开启服务
// 开启PayPal服务
Intent intent = new Intent(this, PayPalService.class);
intent.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION, paypalConfig);
startService(intent);
4.买东西
public void onBuyPressed(View pressed) {
//创建支付对象，用于传过去给PayPal服务器进行收款
PayPalPayment thingToBuy = getThingToBuy(PayPalPayment.PAYMENT_INTENT_SALE);
Intent intent = new Intent(this, PaymentActivity.class);
intent.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION, paypalConfig);
intent.putExtra(PaymentActivity.EXTRA_PAYMENT, thingToBuy);
//这里直接调起PayPal的sdk进行付款操作
startActivityForResult(intent, 1);
}
//这里只传一个总价格或者单个产品的信息收款情况
private PayPalPayment getThingToBuy(String paymentIntent) {
return new PayPalPayment(new BigDecimal("0.01"), "USD", "sample item",
paymentIntent);
}
//这里是购买一系列产品创建购买对象
private PayPalPayment getStuffToBuy(String paymentIntent) {
PayPalItem[] items =
{
new PayPalItem("sample item #1", 2, new BigDecimal("87.50"), "USD",
"sku-12345678"),
new PayPalItem("free sample item #2", 1, new BigDecimal("0.00"),
"USD", "sku-zero-price"),
new PayPalItem("sample item #3 with a longer name", 6, new BigDecimal("37.99"),
"USD", "sku-33333")
};
BigDecimal subtotal = PayPalItem.getItemTotal(items);
BigDecimal shipping = new BigDecimal("7.21");
BigDecimal tax = new BigDecimal("4.67");
PayPalPaymentDetails paymentDetails = new PayPalPaymentDetails(shipping, subtotal, tax);
BigDecimal amount = subtotal.add(shipping).add(tax);
PayPalPayment payment = new PayPalPayment(amount, "USD", "sample item", paymentIntent);
payment.items(items).paymentDetails(paymentDetails);
//--- set other optional fields like invoice_number, custom field, and soft_descriptor
payment.custom("This is text that will be associated with the payment that the app can use.");
return payment;
}
5.接收回调
/**
* 接收支付结果的回调.
*/
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1 && resultCode == Activity.RESULT_OK) {
PaymentConfirmation confirm =
data.getParcelableExtra(PaymentActivity.EXTRA_RESULT_CONFIRMATION);
if (confirm != null) {
try {
//这里可以把PayPal带回来的json数据传给服务器以确认你的款项是否收到或者收全
//可以直接把 confirm.toJSONObject() 这个带给服务器，
//得到服务器返回的结果，你就可以跳转成功页面或者做相应的处理了
Log.i(TAG, confirm.toJSONObject().toString(4));
// confirm.toJSONObject().toString();
Log.i(TAG, confirm.getPayment().toJSONObject().toString(4));
Log.i(TAG, confirm.toJSONObject().toString());
} catch (JSONException e) {
Log.e(TAG, "an extremely unlikely failure occurred: ", e);
}
}
} else if (resultCode == Activity.RESULT_CANCELED) {
Log.i(TAG, "The user canceled.");
} else if (resultCode == PaymentActivity.RESULT_EXTRAS_INVALID) {
Log.i(
TAG,
"An invalid Payment or PayPalConfiguration was submitted. Please see the docs.");
}
}
6.注销service
@Override
protected void onStop() {
stopService(new Intent(this, PayPalService.class));
super.onStop();
}
