Android 错误：不兼容的类型登录屏幕无法转换为onDataListener
我试图通过传递上下文从我的登录类调用AsyncRemoteCall，但它说 服务调用此，无法应用ks 。 登录屏幕： ServiceCalls类： 异步远程调用： 错误图像： 更改登录屏幕以同时实现AsyncRemoteCall.OnDataListenerAndroid 错误：不兼容的类型登录屏幕无法转换为onDataListener,android,Android,我试图通过传递上下文从我的登录类调用AsyncRemoteCall，但它说 服务调用此，无法应用ks 。 登录屏幕： ServiceCalls类： 异步远程调用： 错误图像： 更改登录屏幕以同时实现AsyncRemoteCall.OnDataListener 您在哪里调用新ServiceCal？在loginclass ServiceCalls ServiceCalls=new ServiceCalls这，ks；serviceCalls.executerequestParams；按您所说的做了，但
您在哪里调用新ServiceCal？在loginclass ServiceCalls ServiceCalls=new ServiceCalls这，ks；serviceCalls.executerequestParams；按您所说的做了，但给出了错误，因为OnDataListener无法应用于ServiceCalls类中的android.content.Context。您是否可以在调用新ServiceCalls的登录类中发布更多信息；并指出什么是它的超级级。它甚至实现了AsyncRemoteCall.OnDataListener？？？@petey是的，我现在更新了登录类。。。
