Android實現拼多多地址選擇器
本文實例為大傢分享瞭Android實現拼多多地址選擇器的具體代碼,供大傢參考,具體內容如下
突然想做一款地區選擇器,然後我的彈框用的第三方的,地區數據用的是本地的json文件,解析json文件,然後把數據放在list集合裡面,然後設置到彈框裡面,問題解決
源碼下載地址
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
