基于Smack3.0.4+ Openfire3.10.2开发之Android 客户端之三

源代码下载地址我们在之前依次介绍openfire部署以及smack常用API的使用，这一节中我们着力介绍如何基于asmack开发一个Android的客户端，本篇的重点在实践，讲解和原理环节，大家可以参考前面我所发布的OpenFire和Smack的相关文章。今天所讲解的文章只是 ：基于Smack3.0.4+
Openfire3.10.2开发之Android 客户端之三（用户登入、用户注册与XMPP 服务器交互）。

1、源代码结构介绍：



activity包下存放一些android页面交互相关的控制程序，还有一个些公共帮助类

application包存放时应用程序相关信息

bean包存放应用程序实体对象

db包存放应用程序SQLite封装操作

listener监听器主要存放对XMPP 监听信息封装

server包主要存放应用程序后台服务（主要连接XMPP 服务器）

util中存放一些常用的工具类

view中一些和android的UI相关的显示控件

AndroidManifest.xml为android功能清单的配置文件

2、核心代码介绍

欢迎界面：WelcomeActivity

package com.msn.activity;

import com.msn.util.PreferencesUtils;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.text.TextUtils;
import android.widget.ImageView;

public class WelcomeActivity extends Activity {
//
protected static final String TAG = "WelcomeActivity";
//WelcomeActivity 界面相关组件
private Context mContext;
private ImageView mImageView;
@Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_welcome);
mContext = this;
PreferencesUtils.clearSharePre(this);
findView();
init();
}
private void findView() {
mImageView = (ImageView) findViewById(R.id.iv_welcome);
}
private void init() {
mImageView.postDelayed(new Runnable() {
@Override
public void run() {
Intent intent =null;
String username=PreferencesUtils.getSharePreStr(WelcomeActivity.this, "username");
String pwd=PreferencesUtils.getSharePreStr(WelcomeActivity.this, "pwd");
if(!TextUtils.isEmpty(username)&&!TextUtils.isEmpty(pwd)){
intent = new Intent(mContext, MainActivity.class);
intent.putExtra("isStartService", true);
}else{
