嘿乌尔缺少下列代码得到了一个错误： -

try 
     { 
      sum_aht.call(SUM_SOAP_ACTION, sum_envelope); 
      SoapPrimitive sum_results = (SoapPrimitive)sum_envelope.getResponse(); 
      Log.d("sum_result", sum_results.toString()); 
     // int in = Integer.parseInt(sum_results.getProperty(0).toString()); 
      tv3.setText(""+sum_results.toString()); 
     } 
     catch (Exception e) 
     { 
       tv3.setText(e.getClass().toString()); 
       Log.d("sum_error", e.getClass().toString()); 
      }
