java.lang.ClassCastException : android의 org.ksoap2.serialization.SoapObject

Question

안녕하세요 저는 하나의 안드로이드 응용 프로그램을 개발했습니다.

애플 리케이션 목적은 MySQL 데이터베이스에서 데이터를 검색하고 안드로이드 장치에 표시됩니다.

이 내 안드로이드 코드 :

public class RetailerActivity extends Activity { 
private final String NAMESPACE = "http://ws.testprops.com"; 
    private final String URL = "http://krish.jelastic.servint.net/Retrieve/services/Fetch?wsdl"; 
    private final String SOAP_ACTION = "http://ws.testprops.com/customerData"; 
    private final String METHOD_NAME = "customerData"; 
/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
    envelope.setOutputSoapObject(request); 

    HttpTransportSE ht = new HttpTransportSE(URL); 
    try { 
     ht.call(SOAP_ACTION, envelope); 
     SoapPrimitive response = (SoapPrimitive)envelope.getResponse(); 
     SoapPrimitive s = response; 
     String str = s.toString(); 
     String resultArr[] = str.split("&");//Result string will split & store in an array 

     TextView tv = new TextView(this); 

     for(int i = 0; i<resultArr.length;i++){ 
     tv.append(resultArr[i]+"\n\n"); 
     } 
     setContentView(tv); 

    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
}} 

내가 응용 프로그램을 실행해야하는 경우

만 displayed.it 너무 오래 시간을 또한 내 안드로이드 콘솔 창에 오류가 다음 무엇입니까 약 1 시간 걸리는 빈 화면을 의미한다 :

이 오류를 해결할 수 있도록 도와주세요.

Answer 1

변경

SoapPrimitive response = (SoapPrimitive)envelope.getResponse(); 

SoapObject response = (SoapObject)envelope.getResponse();
