这是我的Android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/update?wsdl"; 
private final String SOAP_ACTION = "http://xcart.com/insertData"; 
private final String METHOD_NAME = "insertData"; 
Button btninsert; 
String selectedItem; 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    //get reference to the spinner from the XML layout 
    Spinner spinner = (Spinner) findViewById(R.id.spnMusketeers); 
    btninsert = (Button)findViewById(R.id.btn_insert); 
    btninsert.setOnClickListener(new View.OnClickListener() { 
     public void onClick(View v) { 
      SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 
      PropertyInfo unameProp =new PropertyInfo(); 
      unameProp.setName("userName");//Define the variable name in the web service method 
      unameProp.setValue(selectedItem);//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){ 
      } 
     } 
    }); 
    //attach the listener to the spinner 
    spinner.setOnItemSelectedListener(new MyOnItemSelectedListener()); 
    //Dynamically generate a spinner data 
    createSpinnerDropDown(); 
} 
//Add animals into spinner dynamically 
private void createSpinnerDropDown() { 
    //get reference to the spinner from the XML layout 
    Spinner spinner = (Spinner) findViewById(R.id.spinner1); 
    //Array list of animals to display in the spinner 
    List<String> list = new ArrayList<String>(); 
    list.add("Q"); 
    list.add("P"); 
    list.add("F"); 
    list.add("I"); 
    list.add("C"); 
    //create an ArrayAdaptar from the String Array 
    ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, 
      android.R.layout.simple_spinner_item, list); 
    //set the view for the Drop down list 
    dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
    //set the ArrayAdapter to the spinner 
    spinner.setAdapter(dataAdapter); 
    //attach the listener to the spinner 
    spinner.setOnItemSelectedListener(new MyOnItemSelectedListener()); 
} 
public class MyOnItemSelectedListener implements OnItemSelectedListener { 
    public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) { 
     selectedItem = parent.getItemAtPosition(pos).toString(); 
} 
    @Override 
    public void onNothingSelected(AdapterView<?> arg0) { 
     // TODO Auto-generated method stub 
    } 
    } 
    public void onNothingSelected(AdapterView<?> parent) { 
     // Do nothing. 
    } 
} 

这是我的web服务代码：

public class update { 
public String insertData(String status,String username){ 
    try{ 
    Class.forName("com.mysql.jdbc.Driver"); 
    Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/xcart-432pro","root",""); 
    PreparedStatement statement = con.prepareStatement("UPDATE `xcart_orders` set `status` = '"+status+"' where `status` = 'Q'"); 
    int result = statement.executeUpdate(); 
    } 
    catch(Exception exc){ 
    System.out.println(exc.getMessage()); 
    } 
    return "Updation successfull!!"; 
    } 
}
