仿美团二级菜单

Posted 2020-07-25

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。
