Android开源组件SlidingMenu的基本使用方法和SlidingMenuDemo
1.下载开源SlidingMenu，去Github下载 https://github.com/jfeinstein10/SlidingMenu。
SlidingMenu是一个强大的侧边栏导航框架，自己去codeKK看了源码分析才有了更多的收获 ：http://codekk.com/open-source-project-analysis/detail/Android/huxian99/SlidingMenu%20源码解析，这个网站codeKK有许多开源项目的源码解析，是个很不错的学习资源，很感谢这些大牛的奉献。力推这个网站codeKK。
此文章只是自己学习笔记记录，看这个大牛写的，自己加之整理学习了下，感兴趣的看他写的，http://blog.csdn.net/yangyu20121224/article/details/9255829。
1>SlidingMenu功能介绍
SlidingMenu 是一个强大的侧边栏导航框架，主要特点如下：
(1) 侧边栏可以是一个 Fragment，包含任何 View
(2) 使用简单方便，支持左滑和右滑等
(3) 自定义侧边栏显示动画
2>总体设计
SlidingMenu 总体由三个主要的类组成。
(1) SlidingMenu 继承自 RelativeLayout，对外暴露 API 给用户，同时在添加 CustomViewAbove 和。 CustomViewBehind
(2) CustomViewAbove 继承自 ViewGroup，主要用来处理触摸屏事件。
(3) CustomViewBehind 继承自 ViewGroup，主要用来配置参数，显示侧边栏的 Menu 部分。
2.下载SlidingMenu直接导入eclipse，自己再新建Android项目，取名SlidingMenuDemo，之后，右击SlidingMenuDemo-->properties->Android->Add(下面)关联SlidingMenu->Apply->OK，就行,参考下图1. 注意关联后，将SlidingMenuDemo项目中lib下的android-support-v4.jar删除，因为SlidingMenu以及存android-support-v4.jar，否则后面在MainActivity.java会报错。
3. 效果图如下，可以左右滑动，
4.项目类以及布局有关介绍，如下图：
5.具体代码：
1>left_function_fragment.xml 为左侧菜单栏布局
2>main_content_frame.xml 为存放右侧菜单内容的Fragment布局
3>menu_frame.xml 是用来存放菜单的Fragment
4>content_item.xml为菜单内容listview的item
5>list.xml为右边每个菜单内容中的Listview布局
6>menu_item.xml为菜单栏中MyListView中的item
在values下的dimens.xml添加了这个2个大小属性：
20dp
40dp 接着是类
1> MenuListFragment.java是左侧菜单类：
