仿美团二级菜单

最近要做一个仿美团似的二级菜单在csdn上找了demo 下载下来有错误不能运行自己又整理了一下终于可以运行实现效果了。布局xml就不贴出代码了，demo可以去csdn去下载：（后续补上链接）

1）分析思路，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。
