這篇文章主要為大家詳細介紹了Android實現(xiàn)拼多多地址選擇器，文中示例代碼介紹的非常詳細，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文實例為大家分享了Android實現(xiàn)拼多多地址選擇器的具體代碼，供大家參考，具體內(nèi)容如下

突然想做一款地區(qū)選擇器，然后我的彈框用的第三方的，地區(qū)數(shù)據(jù)用的是本地的json文件，解析json文件，然后把數(shù)據(jù)放在list集合里面，然后設(shè)置到彈框里面，問題解決

1.效果圖

2.引用builder

implementation 'com.google.code.gson:gson:2.8.0'
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.解析類bean
