Android进阶之路 - 仿京东地址选择器的详细使用
因为现在项目的地址选择器比较low，自己又比较懒，所以就找到了仿京东的地址选择器，观赏几篇博文之后，发现总是被半路卡死，很难一路走到底，所以找到了作者在github的地址，但是作者的功能简介又介绍的不是很详细，总会有一些小的知识点遗漏，到了最后只能非常无奈的查看了源代码，然后实现了自己的功能所需，一些小坑在下方列出，请君观赏。
小坑：
- 文中的展示有俩种方式，第一种是自定义添加到Linearlayout布局中，第二种是以弹框形式展示
- 因作者原始自定义BottomDialog的整体展示不太美观，而代码又限制只又读的权限，故重写了一份BottomDialog，设置了符合自己观赏的BottomDialog
- android中存在一些自定义的color，使用
android.R.color.holo_orange_light进行引用
需掌握知识点：
- 接口回调
- RecyclerView、ListView
- 自定义Dialog
Effect ：
第一种
第二种
