您好我开发了一个登录表单，调用soap webservices.it成功完全为我工作...但现在我实现了一部分。当我的登录详细信息成功意味着它将进入下一个活动。 怎么办......面临一些困难。 编码部分如下。
dis是我的webservices java项目：
package com.userlogin.ws;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
public class Login {
public String authentication(String userName,String password){
String retrievedUserName = "";
String retrievedPassword = "";
String status = "";
try{
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/androidlogin","root","");
PreparedStatement statement = con.prepareStatement("SELECT * FROM user WHERE username = '"+userName+"'");
ResultSet result = statement.executeQuery();
while(result.next()){
retrievedUserName = result.getString("username");
retrievedPassword = result.getString("password");
}
if(retrievedUserName.equals(userName)&&retrievedPassword.equals(password)){
status = "Success!";
}
else{
status = "Login fail!!!";
}
}
catch(Exception e){
e.printStackTrace();
}
return status;
}
}
dis是我的android端编码部分：
package com.androidlogin.ws;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.content.Intent;
public class AndroidLoginExampleActivity extends Activity {
private final String NAMESPACE = "http://ws.userlogin.com";
private final String URL = "http://192.168.1.168:8085/Login/services/Login?wsdl";
private final String SOAP_ACTION = "http://ws.userlogin.com/authentication";
private final String METHOD_NAME = "authentication";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button login = (Button) findViewById(R.id.btn_login);
login.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
loginAction();
}
});
}
private void loginAction(){
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
EditText userName = (EditText) findViewById(R.id.tf_userName);
String user_Name = userName.getText().toString();
EditText userPassword = (EditText) findViewById(R.id.tf_password);
String user_Password = userPassword.getText().toString();
//Pass value for userName variable of the web service
PropertyInfo unameProp =new PropertyInfo();
unameProp.setName("userName");//Define the variable name in the web service method
unameProp.setValue(user_Name);//set value for userName variable
unameProp.setType(String.class);//Define the type of the variable
request.addProperty(unameProp);//Pass properties to the variable
//Pass value for Password variable of the web service
PropertyInfo passwordProp =new PropertyInfo();
passwordProp.setName("password");
passwordProp.setValue(user_Password);
passwordProp.setType(String.class);
request.addProperty(passwordProp);
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.tv_status);
result.setText(response.toString());
}
catch(Exception e){
}
Button registerScreen = (Button) findViewById(R.id.btn_login);
// Listening to register new account link
registerScreen.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Switching to Register screen
Intent i = new Intent(getApplicationContext(), RegisterActivity.class);
startActivity(i);
}
});
}
}
这里当点击按钮意味着它被重定向到下一个活动..但我希望如果成功登录意味着它转到下一个活动....请在哪里放置意图编码或告诉我该怎么做...请指导我。

据我了解您的问题，您必须检查您的登录网络服务电话的响应，并在此基础上制定条件。
如果您的回复包含成功！状态，请启动 NewActivity ，否则显示登录失败Dialog或Toast。
例如：
你的逻辑应该在这里开始新的活动，
try{
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
String status = response.toString();
TextView result = (TextView) findViewById(R.id.tv_status);
result.setText(response.toString());
if(status.equals("Success!"))
{
Intent i = new Intent(getApplicationContext(), NextActivity.class);
startActivity(i);
}
else
{
// Code for Login failure
}
}
catch(Exception e){
}

我更喜欢从AsynTask类内部而不是从onCreate（）内部进行Web服务调用，因为后台操作不应该影响UI线程。
什么是AsyncTask？
AsyncTask可以正确，轻松地使用UI线程。该类允许执行后台操作并在UI线程上发布结果，而无需操纵线程和/或处理程序。
从AsyncTask创建一个类，并为主Activity类中的onPreExecute，onPostExecute，onProgressUpdate和doInBackground方法提供定义：
private class AsyncCallWS extends AsyncTask {
@Override
protected Void doInBackground(String... params) {
//Call Web Method
loginStatus = WebService.invokeLoginWS(editTextUsername,editTextPassword,"authenticateUser");
return null;
}
@Override
//Once WebService returns response
protected void onPostExecute(Void result) {
//Make Progress Bar invisible
webservicePG.setVisibility(View.INVISIBLE);
Intent intObj = new Intent(CheckLoginActivity.this,HomeActivity.class);
//Error status is false
if(!errored){
//Based on Boolean value returned from WebService
if(loginStatus){
//Navigate to Home Screen
startActivity(intObj);
}else{
//Set Error message
statusTV.setText("Login Failed, try again");
}
//Error status is true
}else{
statusTV.setText("Error occured in invoking webservice");
}
//Re-initialize Error Status to False
}
@Override
//Make Progress Bar visible
protected void onPreExecute() {
webservicePG.setVisibility(View.VISIBLE);
}
@Override
protected void onProgressUpdate(Void... values) {
}
}
}
调用AsyncTask的execute方法启动Web Service调用。
//Create instance for AsyncCallWS
AsyncCallWS task = new AsyncCallWS();
//Call execute
task.execute();

This code is Beneficial for you
btnsub.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME1);
//Use this to add parameters
request.addProperty("username",Username.getText().toString());
request.addProperty("Password",password.getText().toString());
//Declare the version of the SOAP request
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
envelope.dotNet = true;
try {
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
//this is the actual part that will call the webservice
androidHttpTransport.call(SOAP_ACTION1, envelope);
// Get the SoapResult from the envelope body.
SoapObject result = (SoapObject)envelope.getResponse();
Log.e("result", "responce"+result);
SoapObject root = (SoapObject) result.getProperty(0);
Log.e("root", "responce"+root);
System.out.println("********Count : "+ root.getPropertyCount());
//value=new ArrayList<Detailinfo>();
for (int i = 0; i < root.getPropertyCount(); i++)
{
SoapObject root1 = (SoapObject) root.getProperty(i);
Log.e("root1", "responce"+root1);
Detailinfo info=new Detailinfo();
info.setResponseCode(root1.getProperty("ResponseCode").toString());
Log.e("code", ""+root1.getProperty("ResponseCode").toString());

//for maintain session
session.createUserLoginSession(info.getCustomerID(),info.getName(),info.getMobile(),info.getEmailID(),info.getAccountType());

Log.e("session"," "+session.toString());
Intent inten=new Intent(getApplicationContext(),AccordionActivity.class);
