Android是什么
Android是一种基于Linux内核的自由及开放源代码的操作系统，主要使用于移动设备，如智能手机和平板电脑，由美国Google公司和开放手机联盟领导及开发。
突然想做一款地区选择器，然后我的弹框用的第三方的，地区数据用的是本地的json文件，解析json文件，然后把数据放在list集合里面，然后设置到弹框里面，问题解决
源码下载地址
效果图
引用builder
implementation 'com.google.code.gson:gson:2.8.0'implementation 'com.contrarywind:Android-PickerView:4.1.9'json文件存放地址：
E:\workspace\android\MyApplication25\app\src\main\assets\citydata.json
