KSOAP を使用して Web サービスを呼び出しています。Web メソッドは完全に機能しており、文字列を「無効」または「有効」として返します。テキストフィールドから取得したユーザー名とパスワードを渡して、有効か無効かを応答しようとしています。エラーは発生しません。log cat に出力されるものと出力されないものを示すコードにコメントしました。Web メソッドから応答を取得する方法に問題があります。私は何を間違っていますか？助けてください

 public class Login extends Activity{

私は何が間違っていたのかを理解しました

それ以外の 

httpTransport.call(SOAP_ACTION, envelope);                       
                     Object response = envelope.getResponse();
                     String result =  response.toString();

私は使用する必要があります

        httptransport.call(SOAP_ACTION, envelope);
        SoapPrimitive resultstring = (SoapPrimitive) soapenvelope
                        .getResponse();
