基本上我正在使用平台通道在本机 android(kotlin) 中调用支付 sdk。SDK 初始化成功。付款交易后,我将在 kotlin 文件中收到付款状态,该文件实际上扩展了 sdk 类文件(不是活动)。从这个回调方法中,我需要将状态传递给颤振飞镖代码。一切都成功运行,没有任何错误,但在传递支付状态时不会调用颤振方法。
颤振飞镖代码。
@override
void initState() {
// TODO: implement initState
super.initState();
platform.setMethodCallHandler(_handlePaymentResponse); // To call from native android after payment response.
}
// Invoked from Native Android after payment response.
Future<dynamic> _handlePaymentResponse(MethodCall call) async {
print('_handlePaymentResponse method called');
switch(call.method) {
case "message":
debugPrint('From Native====' + call.arguments);
return new Future.value("");
}
}
// On button click this method will be invoked.
Future<void> _initializeSDK() async {
print('Token $token');
try {
await platform.invokeMethod('callPaymentSDK');
} on PlatformException catch (e) {
print("Failed to initialize SDK : '${e.message}'.");
}
}
Native Android : Paymentstatus.kt
class PaymentResponse() : LibraryPaymentStatusProtocol, Parcelable {
//val channel = MethodChannel(flutterView, MainActivity.CHANNEL)
var backgroundFlutterView: FlutterNativeView? = null
override fun paymentStatus(p0: String?, p1: Activity?) {
if (p1 != null) {
Handler(Looper.getMainLooper()).post {
Log.v("PaymentResponse", "Main thread called")
backgroundFlutterView = FlutterNativeView(p1, true)
val channel = MethodChannel(backgroundFlutterView, MainActivity.CHANNEL)
channel.invokeMethod("message", p0); // Invoking Flutter method
}
}
}
}
