Java 在android中通过soap ws在mysql数据库中插入微调器值

嗨，我必须开发的应用程序是插入数据库从spinner在mysql数据库通过soap Webseries在android应用程序

我使用了以下Web服务代码：

public class Insertion {

 public String insertData(String userName,String userPassword){

 try{

 Class.forName("com.mysql.jdbc.Driver");
 Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/androidlogin","root","");
 PreparedStatement statement =  con.prepareStatement("INSERT INTO user(status) VALUES ('"+userName+"');");
  int result = statement.executeUpdate();
   }

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

      return "Insertion successfull!!";
      }

   }

我为android spinner示例使用了以下代码：

  public class InsertionExample extends Activity{
  private final String NAMESPACE = "http://xcart.com";
  private final String URL = "http://192.168.1.168:8085/XcartLogin/services/Insertion?wsdl";
  private final String SOAP_ACTION = "http://xcart.com/insertData";
  private final String METHOD_NAME = "insertData";
  Button btninsert;
  private Spinner spnMusketeers;
  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);


    btninsert = (Button)findViewById(R.id.btn_insert);  
    btninsert.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
         insertValues();
        }
    });
  }

  public void insertValues(){


    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
    Spinner userName = (Spinner) findViewById(R.id.spnMusketeers);
    List<String> lsMusketeers = new ArrayList<String>();
    lsMusketeers.add("Q");
    lsMusketeers.add("P");
    lsMusketeers.add("C");

    ArrayAdapter<String> aspnMusketeers = 
      new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, 
       lsMusketeers);
    aspnMusketeers.setDropDownViewResource
       (android.R.layout.simple_spinner_dropdown_item);
    spnMusketeers.setAdapter(aspnMusketeers);

// Set up a callback for the spinner
   spnMusketeers.setOnItemSelectedListener(
    new OnItemSelectedListener() {
        public void onNothingSelected(AdapterView<?> arg0) { }

        public void onItemSelected(AdapterView<?> parent, View v, 
         int position, long id)  {

          // Code that does something when the Spinner value changes
        }

    });
    String user_Name = userName.getContext().toString();


    //Pass value for userName variable of the web service
       PropertyInfo unameProp =new PropertyInfo();
       unameProp.setName("userName");//Define the variable name in the web service method
       unameProp.setValue(user_Name);//Define value for fname variable
       unameProp.setType(String.class);//Define the type of the variable
       request.addProperty(unameProp);


         SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
         envelope.setOutputSoapObject(request);
         HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

         try{
          androidHttpTransport.call(SOAP_ACTION, envelope);
             SoapPrimitive response = (SoapPrimitive)envelope.getResponse();

             TextView result = (TextView) findViewById(R.id.textView2);
             result.setText(response.toString());

      }
      catch(Exception e){

      } 
       // Code that does something when the Spinner value changes
     }
     }

请帮助我…这里发生了什么错误。请给我解决方案…

将此代码用于此插入函数：

String selectedItem = parent.getItemAtPosition(pos).toString();

String selectedItem = parent.getItemAtPosition(pos).toString();
