Android实现拼多多地址选择器
来源：jb51　　时间：2021/5/10 8:45:57　　对本文有异议

本文实例为大家分享了Android实现拼多多地址选择器的具体代码，供大家参考，具体内容如下

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

1.效果图

2.引用builder

  1. implementation 'com.google.code.gson:gson:2.8.0'
  2. implementation 'com.contrarywind:Android-PickerView:4.1.9'

3.json文件存放地址：

E:\workspace\android\MyApplication25\app\src\main\assets\citydata.json

4.解析类bean

  1. package com.example.myapplication25;
