Android的Web服务的XML解析

Question

我创建了两个Java文件，一个是Main.java和Category.java

我加入库文件ksoap2-Android的组装2.6.2-JAR-与-dependencies.jar

但是这里输出不显示。

我正在做soap xml解析。

在这里文本视图，但我想要一个列表。请帮我

Main.java

public class Main extends Activity {

    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 
    envelope.addMapping(NAMESPACE, "Category",new Category().getClass()); 

    try { 
    androidHttpTransport.call(SOAP_ACTION, envelope); 

    SoapObject response = (SoapObject) envelope.getResponse(); 
    Category[] Allrooms = RetrieveFromSoap(response); 

    TextView actv = (TextView)findViewById(R.id.resultbox); 
    actv.setHint(Allrooms[0].Text1); 
    } catch (Exception e) {

    } 

    public static Category[] RetrieveFromSoap(SoapObject soap)

    Category.Text3= pii.getProperty(2).toString(); 
    categories[i] = category;
