如何在Android中创建登录页面。（使用ksoap2 web服务sharepoint）

我是Android新手。我试图创建登录页面，但总是出错。

    import org.ksoap2.SoapEnvelope;
    import org.ksoap2.serialization.SoapObject;
    import org.ksoap2.serialization.SoapSerializationEnvelope;
    import org.ksoap2.transport.HttpTransportSE;
    import android.app.Activity;
    import android.content.Intent;
    import android.os.Bundle;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.Button;
    import android.widget.EditText;

    public class Main extends Activity {

    private final String NAMESPACE = "http://schemas.microsoft.com/sharepoint/soap/";
    private final String URL = "http://ipaddress/_vti_bin/authentication.asmx?WSDL";

    String username;
    String password;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button signin = (Button) findViewById(R.id.regsubmitbtn);
        signin.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {

                EditText etxt_user = (EditText) findViewById(R.id.usereditlog);
                username = etxt_user.getText().toString();
                EditText etxt_password = (EditText)  findViewById(R.id.pwdeditlog);
                password = etxt_password.getText().toString();
                Login(username,password);
            }
        });   
    }
    private void Login(String user, String pass) {   


        final String SOAP_ACTION = "http://schemas.microsoft.com/sharepoint/soap/Login";
        final String METHOD_NAME = "Login";     
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        request.addProperty("username",user);
        request.addProperty("password",pass);
        SoapSerializationEnvelope envelope = new   SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true; 
        envelope.setOutputSoapObject(request);
        System.out.println(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        try {
            androidHttpTransport.call(SOAP_ACTION, envelope);
            Intent i = new Intent(Main.this,List.class);
            startActivity(i);
        }
        catch (Exception e) {
            e.printStackTrace();
        }

    }

}

我添加了ksoap2.java和互联网权限。

    import org.ksoap2.SoapEnvelope;

    public class Main extends Activity {

    private final String NAMESPACE = "http://schemas.microsoft.com/sharepoint/soap/";
    private final String URL = "http://ipaddress/_vti_bin/authentication.asmx?WSDL";

    String username;
    String password;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button signin = (Button) findViewById(R.id.regsubmitbtn);
        signin.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {

                EditText etxt_user = (EditText) findViewById(R.id.usereditlog);
                username = etxt_user.getText().toString();
                EditText etxt_password = (EditText)  findViewById(R.id.pwdeditlog);
                password = etxt_password.getText().toString();
                Login(username,password);
            }
        });   
    }
    private void Login(String user, String pass) {   


        final String SOAP_ACTION = "http://schemas.microsoft.com/sharepoint/soap/Login";
        final String METHOD_NAME = "Login";     
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        request.addProperty("username",user);
        request.addProperty("password",pass);
        SoapSerializationEnvelope envelope = new   SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true; 
        envelope.setOutputSoapObject(request);
        System.out.println(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        try {
            androidHttpTransport.call(SOAP_ACTION, envelope);
            Intent i = new Intent(Main.this,List.class);
            startActivity(i);
        }
        catch (Exception e) {
            e.printStackTrace();
        }

    }

}

这是我的代码。

    import android.os.Bundle;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.Button;
    import android.widget.EditText;

    public class Main extends Activity {

    private final String NAMESPACE = "http://schemas.microsoft.com/sharepoint/soap/";
    private final String URL = "http://ipaddress/_vti_bin/authentication.asmx?WSDL";

    String username;
    String password;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button signin = (Button) findViewById(R.id.regsubmitbtn);
        signin.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {

                EditText etxt_user = (EditText) findViewById(R.id.usereditlog);
                username = etxt_user.getText().toString();
                EditText etxt_password = (EditText)  findViewById(R.id.pwdeditlog);
                password = etxt_password.getText().toString();
                Login(username,password);
            }
        });   
    }
    private void Login(String user, String pass) {   


        final String SOAP_ACTION = "http://schemas.microsoft.com/sharepoint/soap/Login";
        final String METHOD_NAME = "Login";     
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        request.addProperty("username",user);
        request.addProperty("password",pass);
        SoapSerializationEnvelope envelope = new   SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true; 
        envelope.setOutputSoapObject(request);
        System.out.println(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        try {
            androidHttpTransport.call(SOAP_ACTION, envelope);
            Intent i = new Intent(Main.this,List.class);
            startActivity(i);
        }
        catch (Exception e) {
            e.printStackTrace();
        }

    }

}

当单击登录按钮时，该按钮必须更改为其他页面，但出现错误。

从URL中删除“？WSDL”。如果您仍然有问题，请更新您的帖子，并提供您收到的错误消息的更多详细信息

private final String URL = "http://ipaddress/_vti_bin/authentication.asmx";

您能发布收到的错误消息吗？您是在使用url，还是使用真实的ip地址而不是ip地址这是一个错误“应用程序JobRequest（process com.app.JobRequest）意外停止。请重试。”并在弹出窗口上运行。jobrequest是我的项目名称。我忘了告诉你。web服务在我的计算机上。“ipaddress/_vti_bin/authentication.asmx？WSDL”我在上面使用我的ip地址。
