Android实现拼多多地址选择器

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

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.解析类bean

package com.example.myapplication25;
 
 
import java.io.serializable;
import java.util.list;
 
public class citybean {
    /**
     * code : 200
