Java 计数值通过soap Web服务显示在android emulator上

我曾尝试在Android中显示一个值，该值是通过soap调用检索的。但我不能让它工作。如果我运行我的应用程序，计数值将显示在我的tomcat apache上。但是我的android仿真器上没有显示计数值。为什么这里不显示计数值。 请帮帮我。我知道原因。但我搞不懂代码部分。我的错误是我的android代码部分。在那里我可以更改我的代码

这是我的Web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();
       }
      }
      }

公共类RetailerActivity扩展活动{
私有静态最终字符串SOAP_ACTION=”http://xcart.com/customerData";
私有静态最终字符串方法\u NAME=“customerData”；
私有静态最终字符串命名空间=”http://xcart.com";
私有静态最终字符串URL=”http://192.168.1.168:8085/XcartLogin/services/RetailerWs?wsdl";
/**在首次创建活动时调用*/
@凌驾
创建时的公共void（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；
setContentView（R.layout.retrieve）；
SoapObject请求=新的SoapObject（名称空间、方法名称）；
SoapSerializationEnvelope=新的SoapSerializationEnvelope（SoapEnvelope.VER11）；
envelope.setOutputSoapObject（请求）；
HttpTransportSE ht=新的HttpTransportSE（URL）；
试一试{
ht.呼叫（SOAP_动作、信封）；
SoapPrimitive响应=（SoapPrimitive）信封.getResponse（）；
SOAPs=响应；
字符串str=s.toString（）；
String resultArr[]=str.split（&）；//结果字符串将拆分并存储在数组中
TextView tv=新的TextView（此）；
对于（int i=0；i您确定您在TextView中获得了一些值吗？您可以按照以下方式在android中设置TextView

 LinearLayout lLayout = (LinearLayout)findViewById(R.id.l_layout); // This is my main layout

 TextView tv = new TextView(this);
 tv.setText("Akshay");  // Here I set the value to TextView
 lLayout.addView(tv);   // Here I am adding this view in main View.

希望这有帮助：）
