Question

我正在尝试使用以xsd：string响应的Web服务填充android listview。

我有以下代码，并且已经向清单添加了Internet权限。

但是我得到了一个我根本不理解的错误。在代码下你可以找到我的logcat。

希望有人可以给我一些建议。

谢谢！

    public class ActividadPrincipal extends Activity {

    final String NAMESPACE = "http://android.trucka.com/";
    final String URL = "http://192.168.2.105/SumadorWS/ServicioAndroid.asmx";
    final String SOAP_ACTION = "http://android.trucka.com/InsertarMacro";
    final String METHOD_NAME = "InsertarMacro";

    private SoapObject request = null;
    private SoapSerializationEnvelope envelope = null;
    private SoapPrimitive resultRequestsSOAP = null;

    Gson gson;

    ListView lsvAndroidOS;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_actividad_principal);

        setTitle("Directorio");

        request = new SoapObject(NAMESPACE, METHOD_NAME);
        envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;

        envelope.setOutputSoapObject(request);

        HttpTransportSE transporte = new HttpTransportSE(URL);

        try{
            transporte.call(SOAP_ACTION,envelope);
            resultRequestsSOAP =(SoapPrimitive)envelope.getResponse();
        }catch(IOException e){
            e.printStackTrace();
        }catch(XmlPullParserException e){
            e.printStackTrace();
        }

        String strJSON = resultRequestsSOAP.toString();

        crearLista(strJSON);
    }

    private void crearLista(String strJSON) {
        gson = new Gson();

        Type lstT = new TypeToken< ArrayList>(){}.getType();

        ArrayList arrListAOS= new ArrayList();

        arrListAOS = gson.fromJson(strJSON, lstT);

        lsvAndroidOS.setAdapter(new ArrayAdapter(getApplicationContext(), android.R.layout.simple_list_item_1,arrListAOS));
    }
}

logcat的：
