为什么我无法从网络服务获得结果？当我调试代码时，它显示异常。

以下代码适用于Web服务请求。

    @SuppressWarnings("deprecation")
protected boolean UserNameAvailability(final String sUserName)
{   
    boolean result = false;

    SoapObject request = new SoapObject(getResources().getString(R.string.targetnamespace), getResources().getString(R.string.usernameavailabilitymethod));
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;

    PropertyInfo piUserName = new PropertyInfo();
    piUserName.name = "UserName";

    request.addProperty(piUserName, sUserName);

    HttpTransportSE httpTransport = new HttpTransportSE(getResources().getString(R.string.webserviceurl));                 
        try {
            httpTransport.debug =true;
            httpTransport.call(getResources().getString(R.string.usernameavailabilitysoapaction), envelope);                    
            SoapPrimitive response = (SoapPrimitive)envelope.getResponse(); 
            if (!response.toString().equals("false")) {
                result = true;

            }
            //else
            //{
           //   alertBox("User Name already exists.Please enter different username.");
           // }

          }catch (Exception exception) {
              Log.w("UserNameAvailability - RegisterActivity", "Error message is "+exception.getMessage(), exception);
          }


          return result;
}

Answer 1

@Prakash查看下面的代码，该代码从活动中调用Web服务

public class FirstAppUI extends Activity 
{

    private static final String NAMESPACE = "test.org";
    private static final String URL = 
    "http://localhost:8080/AndriodBackend/services/listServices/server-config.wsdd";    
    private static final String SOAP_ACTION = "Test";
    private static final String METHOD_NAME = "rate";

     private static final String[] sampleACTV = new String[] {"android", "iphone", blackberry"};

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        ArrayAdapter<String> arrAdapter = new ArrayAdapter<String>
        (this, android.R.layout.simple_dropdown_item_1line, sampleACTV);

        AutoCompleteTextView ACTV = (AutoCompleteTextView)findViewById
                        (R.id.AutoCompleteTextView01);
        ACTV.setAdapter(arrAdapter);
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);        
        SoapSerializationEnvelope envelope =new SoapSerializationEnvelope(SoapEnvelope.VER11); 

        envelope.setOutputSoapObject(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

        try {   
                androidHttpTransport.call(SOAP_ACTION, envelope);
            SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn;
            ACTV.setHint("Received :" + resultsRequestSOAP.toString());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Answer 2

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

 if (!response.toString().equals("false")) 
       result = true;

尝试使用以下内容可能会解决您的问题。

 SoapObject resultRequestSOAP = (SoapObject) envelope.bodyIn;

 String resultString = resultRequestSOAP.getProperty(0).toString();

resultString你得到的结果是真或假。
