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

突然想做一款地區選擇器，然后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，然后把數據放在list集合里面，然后設置到彈框里面，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:workspaceandroidMyApplication25appsrcmainassetscitydata.json

4.解析類bean

7.布局頁面就是一個button和一個textview，請自行添加
