Android 通过kSoap将对象发送到webservice

我有一个登录视图，当用户输入用户名、密码时，我需要将它们发送到Web服务。 然后，服务将验证凭据并返回一个ID（customerid）

需要向服务发送“凭据”类的对象

班级：

public class Credetials {

    private String username;
    private String password;


    public Credetials(){}

    public String getUserName(){
        return this.username;
    }
    public void setUserName(String uname){
        this.username=uname;
    }

    public String getPassword(){
        return this.password;
    }
    public void setPassword(String password){
        this.password=password;
    }


}

视图/活动：

loginButton.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {

            /* reading username and password*/
            String username=loginname.getText().toString();
            String password=logincode.getText().toString();

            Credetials credentials=new Credetials();
            credentials.setUserName(username);
            credentials.setPassword(password);

            Log.d("username", credentials.getUserName());
            Log.d("password", credentials.getPassword());
            **// here i have proper username and password.**

            new callGetCustomerId().execute(credentials);


        }
    });
class callGetCustomerId extends AsyncTask<Object, Void, String>{
    @Override
    protected String doInBackground(Object... params) {

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 
        request.addProperty("credentials", params[0]);
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

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

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

            return response.toString();


        }catch(Exception e){
            return e.getMessage();
        }

    }
    @Override
    protected void onPostExecute(String result){
        super.onPostExecute(result);
        Toast.makeText(getApplicationContext(), result, Toast.LENGTH_SHORT).show();

    }
}

这是一项活动：

私有静态最终字符串SOAP_ACTION=”“；
私有静态最终字符串NAMESPACE=“mynamespace”；
私有静态最终字符串方法\u NAME=“getCustomerId”；
私有静态最终字符串URL=“myurl”；
异步任务

类callGetCustomerId扩展了AsyncTask{
@凌驾
受保护的字符串doInBackground（对象…参数）{
SoapObject请求=新的SoapObject（名称空间、方法名称）；
Credetials cred=新的Credetials（“用户名”、“密码”）；
PropertyInfo credPropertyinfo=新的PropertyInfo（）；
credPropertyinfo.setName（“凭证”）；
credPropertyinfo.setValue（cred）；
credPropertyinfo.setType（cred.getClass（））；
request.addProperty（credPropertyinfo）；

我已经在输出转储上面写过了

您必须序列化凭证类。尝试在该类中实现序列化。如果您愿意，您可以简单地执行类似“request.addProperty（“用户名”，您的用户）；request.addProperty（“密码，您的通行证”）；”这样的操作。根据WSDL契约，我尝试了公共类Credetials实现Serializable（）…但没有成功。还是一样的错误，等等。现在你可以提出要求了。FaultString来自服务器，所以您可以进行连接。响应的类型取决于WS-contract和服务器。好的..那么我现在需要尝试什么呢？？你想看WSDL吗？还是别的什么？我现在有点迷路了……没错。发布WSDL。“request.addProperty（，）”，方法名称，命名空间，soapAction。。。依赖WSDL契约
