【问题描述】：

我希望通过android中的soap webservice在mysql数据库中插入下拉值...如果我必须从我的android应用程序中更改下拉值意味着更新值也保存在mysql数据库中...该怎么做。请帮帮我。

这是我的网络服务代码：

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!!";
     

     

这是我的安卓代码：

    public class InsertionExample extends Activity
    private final String NAMESPACE = "http://ws.retailer.com";
private final String URL = "http://192.168.1.168:8085/Retailer/services/GetCurrentDateTime?wsdl";
private final String SOAP_ACTION = "http://ws.retailer.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()
Spinner userName = (Spinner) findViewById(R.id.spnMusketeers);
    String user_Name = userName.getContext().toString();

 spnMusketeers = (Spinner) findViewById(R.id.spnMusketeers);
 List<String> lsMusketeers = new ArrayList<String>();
 lsMusketeers.add("Q");
 lsMusketeers.add("C");
 lsMusketeers.add("P");
 lsMusketeers.add("I");
 lsMusketeers.add("F");

 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)  
         SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
         PropertyInfo unameProp =new PropertyInfo();
         unameProp.setName("spnMusketeers");//Define the variable name in the web service method
         unameProp.setValue(status);//Define value for fname variable
         unameProp.setType(String.class);//Define the type of the variable
         request.addProperty(unameProp);//Pass properties to the variable



         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
     
 );

   

  

如果我必须在单击插入按钮后从微调器中选择值意味着它没有被插入。应用程序被强制关闭...请检查我的代码并为我提供正确的解决方案。

【参考方案1】：

为这个插入函数使用下面的代码：

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