这是我的代码,它工作正常。声明这些常量是类范围。注意:开发人员 Paypal 中的应用程序页面中有两个客户端 ID。一个在“测试凭据”中,另一个在“实时凭据”下,您应该单击“显示”链接才能看到它。如果您想发布您的应用程序,请选择“实时凭据”的客户端 ID。
private static final String PAYPAL_CLIENT_ID = "YOUR-CLIENT-IT";
private static final String PAYPAL_RECEIVER_EMAIL = "YOUR-EMAIL";
然后在 onCreate() 中定义服务:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// start Paypal service
Intent intent = new Intent(this, PayPalService.class);
// live: don't put any environment extra
// sandbox: use PaymentActivity.ENVIRONMENT_SANDBOX
intent.putExtra(PaymentActivity.EXTRA_PAYPAL_ENVIRONMENT, PaymentActivity.ENVIRONMENT_PRODUCTION);
intent.putExtra(PaymentActivity.EXTRA_CLIENT_ID, PAYPAL_CLIENT_ID);
startService(intent);
}
当用户点击按钮时,将运行以下方法:
private void openDonateBtnPressed(BigDecimal donation) {
PayPalPayment payment = new PayPalPayment(donation, "USD", "Donation");
Intent intent = new Intent(this, PaymentActivity.class);
// comment this line out for live or set to PaymentActivity.ENVIRONMENT_SANDBOX for sandbox
intent.putExtra(PaymentActivity.EXTRA_PAYPAL_ENVIRONMENT, PaymentActivity.ENVIRONMENT_PRODUCTION);
// it's important to repeat the clientId here so that the SDK has it if Android restarts your
// app midway through the payment UI flow.
intent.putExtra(PaymentActivity.EXTRA_CLIENT_ID, PAYPAL_CLIENT_ID);
// Provide a payerId that uniquely identifies a user within the scope of your system,
// such as an email address or user ID.
intent.putExtra(PaymentActivity.EXTRA_PAYER_ID, "<someuser@somedomain.com>");
intent.putExtra(PaymentActivity.EXTRA_RECEIVER_EMAIL, PAYPAL_RECEIVER_EMAIL);
intent.putExtra(PaymentActivity.EXTRA_PAYMENT, payment);
startActivityForResult(intent, 0);
}
这是 onActivityResult():
@Override
protected void onActivityResult (int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK) {
PaymentConfirmation confirm = data.getParcelableExtra(PaymentActivity.EXTRA_RESULT_CONFIRMATION);
if (confirm != null) {
try {
Toast.makeText(RateTheAppActivity.this, R.string.rate_donation_received, Toast.LENGTH_LONG).show();
Log.d(TAG, confirm.toJSONObject().toString(4));
} catch (JSONException e) {
Log.e(TAG, "an extremely unlikely failure occurred: ", e);
}
}
}
else if (resultCode == Activity.RESULT_CANCELED) {
Log.d(TAG, "The user canceled.");
}
else if (resultCode == PaymentActivity.RESULT_PAYMENT_INVALID) {
Log.e(TAG, "An invalid payment was submitted. Please see the docs.");
}
}
