这是我的安卓代码：
public class InsertionExample extends Activity {

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//get reference to the spinner from the XML layout

}
catch(Exception e){
}
}
});
//attach the listener to the spinner

}
@Override

// TODO Auto-generated method stub
}
}
public void onNothingSelected(AdapterView<?> parent) {
// Do nothing.
}
}
这是我的网络服务代码：
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!!";
}
}
请帮助我..为什么我的更新对我不起作用...
