我们在常用的电商或者旅游APP中，例如美团，手机淘宝等等，都能够看的到有那种下拉式的二级列表菜单。具体如图所示：
上面两张图就是美团的一个二级列表菜单的一个展示。我相信很多人都想开发一个跟它一样的功能放到自己的APP中。好，接下来我们就开始动手，解决它。
1，结构分析#
首先，我们给出这个下来菜单需要的组建。我们用线框图来分析。
1）如上图所示，最外围的是一个Activity，顶部包含了一个View的容器，这个容器主要是装载ToggleButton来实现诸如美团里面的“美食，全城，理我最近，刷选”这一行。这一行一点就会弹出对应的下来菜单。
2）下拉菜单是如何实现的呢？，这里我们利用了PopupWindow来实现这一弹出式窗口。然后我们在弹出式窗口里面再定义我们的下来列表项，是单列还是二级菜单，都是由里面来定。
3）不同的菜单，需要一级或者需要二级，在这里根据我的需求而变动。我们在PopupWindow上面加一个自定义的LeftView，或者是MiddleView，RightView。主要是一个ToggleButton，你弹出一个窗口，你就定制一个窗口。
3）视图里面嵌入ListView，就形成了列表项。
好分析就到上面为止，接下来我们一步步的说明实现。
2，项目结构#
本项目的项目结构如图所示：
1） Adapter。适配器，主要是为ListView提供数据适配的。
2）MainActivity。主活动页面。
3）ExpandTabView。本项目的核心类，它包含ToggleButton容器和PopupWindow，是控制弹出窗口的核心类。
4）ViewLeft,ViewMiddle,ViewRight。是弹出里面嵌套的类，实现不同的列表菜单。
3，MainActivity#
承载所有元素。看代码比看文字实在。

最主要就是如何处理当我们点击这些ToggleButton的时候要弹出或者收起这些PopupWindow。
