Android实现拼多多地址选择器-编程学习网

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

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;

public class CityBean {
    
 
    private int code;

        this.code = code;
    }
 
    public String getMessage() {
        return message;
    }
 
    public void setMessage(String message) {
        this.message = message;
    }
 
    public DatasBean getDatas() {
        return datas;
    }
 
    public void setDatas(DatasBean datas) {
        this.datas = datas;
    }
 
    public static class DatasBean implements Serializable {

        }

                private List<ArealistBean> arealist;
 
                public String getArea_id() {
                    return area_id;
                }
 
                public void setArea_id(String area_id) {

                public String getArea_name() {
                    return area_name;
                }

                    this.area_name = area_name;
                }
 
                public List<ArealistBean> getArealist() {
                    return arealist;
                }
 
                public void setArealist(List<ArealistBean> arealist) {
                    this.arealist = arealist;
                }
 
                public static class ArealistBean implements Serializable {
                    
 
                    private String area_id;

                }
            }
        }
    }
