Webservices（屏幕不顯示任何響應）

Question

這裏是完整的代碼..在運行應用程序後，屏幕變爲空白。沒有輸出。我加HTTP：10.0.2.2，因爲我使用

的Java

package com.example.final_mobile; 

import org.ksoap2.SoapEnvelope; 
import org.ksoap2.serialization.SoapObject; 
import org.ksoap2.serialization.SoapSerializationEnvelope; 
import org.ksoap2.transport.HttpTransportSE; 

import android.app.Activity; 
import android.os.Bundle; 
import android.os.StrictMode; 
import android.widget.TextView; 

public class AndroidClassActivity extends Activity { 
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder() 
     .permitAll().build(); 
private static final String SOAP_ACTION = "http://srfsolution.com/GetClients"; 

private static final String OPERATION_NAME = "GetClients"; 

private static final String WSDL_TARGET_NAMESPACE = "http://srfsolution.com/"; 

private static final String SOAP_ADDRESS = 
    "http://10.0.2.2:8080/Web_Service/WebService.asmx?wsdl"; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    StrictMode.setThreadPolicy(policy); 
    TextView textView = new TextView(this); 

    setContentView(textView); 

    SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE, 
      OPERATION_NAME); 

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
      SoapEnvelope.VER11); 
    envelope.dotNet = true; 

    envelope.setOutputSoapObject(request); 

    HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS); 

    try 

    { 

     httpTransport.call(SOAP_ACTION, envelope); 

     Object response = envelope.getResponse(); 

     textView.setText(response.toString()); 

    } 

    catch (Exception exception) 

    { 

     textView.setText(exception.toString()); 

    } 

} 
}

Answer 1

嘗試設置輸入數據。它看起來像你沒有設置請求參數。例如，

SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE, OPERATION_NAME); 

request.addProperty("driverid", "MYAPPDRIVER01");
