Ksoap简单数组Android

Question

I'm trying to retrieve data from web service that returns an array of Strings . I couldn't do it so I give you a snippet of code
please help me I'm going crazy!

public void updateCategories(){
        SOAP_ACTION = "http://app.market_helper.com/getCategories";
        METHOD_NAME = "getCategories";
        Log.i("MESSAGE FROM me", "It's running wtf");
        try {
            SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                    SoapEnvelope.VER11);
            envelope.setOutputSoapObject(request);
            HttpTransportSE androidHttpTransport = new HttpTransportSE(
                    URL);
            androidHttpTransport.call(SOAP_ACTION, envelope);
            SoapObject response = (SoapObject)envelope.getResponse();
        Log.i("message to me",""+response.getPropertyCount());
        }catch (Exception e) {
            e.printStackTrace();
        }
    }

I can retrieve data from primitive types but this is going a little bit complex . this is the response from the web service

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<getCategoriesResponse xmlns="http://DefaultNamespace">
  <getCategoriesReturn>desktop computers</getCategoriesReturn> 
  <getCategoriesReturn>laptop computers</getCategoriesReturn> 
  <getCategoriesReturn>mobile phones</getCategoriesReturn> 
  <getCategoriesReturn xsi:nil="true" /> 
  <getCategoriesReturn xsi:nil="true" /> 
  <getCategoriesReturn xsi:nil="true" /> 
  <getCategoriesReturn xsi:nil="true" /> 
  <getCategoriesReturn xsi:nil="true" /> 
  <getCategoriesReturn xsi:nil="true" /> 
  <getCategoriesReturn xsi:nil="true" /> 
  <getCategoriesReturn xsi:nil="true" /> 
  <getCategoriesReturn xsi:nil="true" /> 
  <getCategoriesReturn xsi:nil="true" /> 
  <getCategoriesReturn xsi:nil="true" /> 
  <getCategoriesReturn xsi:nil="true" /> 
  <getCategoriesReturn xsi:nil="true" /> 
  <getCategoriesReturn xsi:nil="true" /> 
  <getCategoriesReturn xsi:nil="true" /> 
  <getCategoriesReturn xsi:nil="true" /> 
  <getCategoriesReturn xsi:nil="true" /> 
  </getCategoriesResponse>
  </soapenv:Body>
  </soapenv:Envelope> 

thanks in advance

Answer 1

You should be able to get the string values with response.getProperty(index).toString() or if you want, response.getPropertyAsString(index) (index can also be replaced with the name of the property). To retrieve all string values, try putting them into a loop which adds the strings into a list.

List<String> categories = new ArrayList<String>();
int count = response.getPropertyCount();

for(int i = 0; i < count; i++) {
    if(response.getProperty(i) != null)
        categories.add(response.getPropertyAsString(i));
}

I also make sure that the property is not null before adding it into the list.

Does this work for you?

This line:

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

should be changed to:

SoapObject response = (SoapObject)envelope.bodyIn;

to use:

response.getProperty(Index);
