基于Smack3.0.4+ Openfire3.10.2开发之Android 客户端之一

野性酷女 2023-10-16 22:39 34阅读 0赞

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 客户端之一（登入界面设计和实现）。

1、源代码结构介绍：

![Center][]

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

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，我们这里开放的权限并不多

2、核心代码介绍

WelcomeActivity.java
