從Web服務收到的響應爲空

我正在使用使用KSOAP的Web服務發送要存儲在數據庫中的詳細信息。我用Visual Studio創建了Web服務。該Web服務正常工作。細節被插入到數據庫中時將返回一個字符串。問題是這個字符串是空的，也許在我得到響應的方式上有些問題。我一直在努力弄清楚什麼是錯誤的。請幫助從Web服務收到的響應爲空

public class Registration extends Activity{ 
private static final String SOAP_ACTION = "http://tempuri.org/register"; 
private static final String OPERATION_NAME = "register"; 
private static final String WSDL_TARGET_NAMESPACE = "http://tempuri.org/"; 
private static final String SOAP_ADDRESS = "http://10.0.2.2:58076/WebSite1/Service.asmx"; 
Button sqlRegister, sqlView; 

EditText sqlFirstName,sqlLastName,sqlEmail,sqlMobileNumber,sqlCurrentLocation,sqlUsername,sqlPassword; 

@Override

super.onCreate(savedInstanceState); 
setContentView(R.layout.registration); 
sqlFirstName = (EditText) findViewById(R.id.etFname); 
sqlLastName = (EditText) findViewById(R.id.etLname); 
sqlEmail = (EditText) findViewById(R.id.etEmail);

sqlRegister.setOnClickListener(new View.OnClickListener() { 

    public void onClick(View v) { 
     switch (v.getId()){

     return null; 

    }  

    @Override

你必須改變的價值SOAP_ACTION。 'SOAP_ACTION'是'http：// tempuri.org/register'。它應該是'http：//10.0.2.2：58076/WebSite1/Service.asmx' – adatapost 2012-07-11 07:38:43

嘗試仍然是一樣的。 – 2012-07-11 07:59:23

首先使用SOAPUI工具來查看您的SOAP響應是否正如您所願.. – YuDroid 2012-07-11 08:23:16

你的web服務返回String。嘗試使用此方法解決你的問題

  Object result = envelope.getResponse();

時類型字節的web服務的返回值[]，你可以這樣做：

  SoapObject response=(SoapObject)envelope.bodyIn;

希望它可以幫助
