Question

我尝试在Android中显示一个值，该值是通过soap调用检索的。但我不能让它发挥作用。如果我运行我的应用程序，计数值将显示在我的tomcat-apache上。但计数值不会显示在我的Android模拟器上。为什么这里没有显示计数值。请帮我。我知道原因。但我无法弄清楚代码部分。我的错误是我的android代码部分。我可以在哪里更改我的代码。

这是我的网络服务代码：

public class RetailerWs {

public String customerData(){
String customerInfo = "";
try{
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/xcart-432pro","root","");
//Find customer information where the customer ID is maximum
PreparedStatement statement =  con.prepareStatement("select * from xcart_orders where status='Q' AND date = CURDATE()");

 ResultSet result = statement.executeQuery();

  int count=0;    
   while(result.next()){

 count++;
 System.out.println(count);
 }
  }

 catch(Exception exc){
    System.out.println(exc.getMessage());
  }

   return customerInfo;
    }

   }

这是我的android代码部分：

   public class RetailerActivity extends Activity {
   private static final String SOAP_ACTION = "http://xcart.com/customerData";
   private static final String METHOD_NAME = "customerData";
   private static final String NAMESPACE = "http://xcart.com";
   private static final String URL = "http://192.168.1.168:8085/XcartLogin/services/RetailerWs?wsdl";
     /** Called when the activity is first created. */
    @Override
   public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.retrieve);
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

    envelope.setOutputSoapObject(request);

    HttpTransportSE ht = new HttpTransportSE(URL);
    try {
        ht.call(SOAP_ACTION, envelope);
        SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
        SoapPrimitive s = response;
        String str = s.toString();
        String resultArr[] = str.split("&");//Result string will split & store in an array

        TextView tv = new TextView(this);

        for(int i = 0; i<resultArr.length;i++){
        tv.append(resultArr[i]+"\n\n");
       }
        setContentView(tv);

    } catch (Exception e) {
        e.printStackTrace();
       }
      }
      }

我应该在哪里更改我的android代码以在android模拟器上打印计数值。

计数值通过soap webservice显示在android模拟器上
