BRVAH BaseMultiItemQuickAdapter多布局实现
这几天有个需求是来了新的设计图，重构租屋列表页，犹豫最近撸了个筛选框，然后列表页UI也变了，跟同事沟通后，建议我重构这个模块，在看完设计图后，我发现现在很多APP的列表页，都趋于多布局的情况
下面距离，懂球帝APP
这样看图，我们可以很明显的发列表item里面突然多了一个，广告或者别的类型的ITEM，如果你是电商模块 新闻模块可能更多不同样子的布局了，抛出第一个问题，如果是你，你会怎么去实现这个玩意
接下来 我们用图来深刻解释
从这个图可以看出来 这个列表 本来item子项里面都是圆形的，却多了2个不一样的，这就是所谓的多布局
刚好项目里面有用到 bravh，深入后发现这个库真的很强大

一下就来说说我demo实现后的样子
我这个里面的多布局就是 中间多了一个滑动的布局
接下来 上代码
item_one
item_two
这个是头部，我手动代码addheaderview的 头部布局
two_img
滑动布局里面的控件布局
