Android模拟iOS的PickerView并且附带全国所有省城市地区三级目录

首先来张效果图：

PickerView的加载路径：

compile 'com.bigkoo:pickerview:2.0.8'

数据加载和解析：

private ArrayList<ProvinceBean> options1Items = new ArrayList<ProvinceBean>();
private ArrayList<ArrayList<String>> options2Items = new ArrayList<ArrayList<String>>();
private ArrayList<ArrayList<ArrayList<String>>> options3Items = new ArrayList<ArrayList<ArrayList<String>>>();

public static void getAllAreaPlace(ArrayList<ProvinceBean> options1Items, ArrayList<ArrayList<String>> options2Items, ArrayList<ArrayList<ArrayList<String>>> options3Items) {
    AllAreaBean allAreaBean = JSON.parseObject(AllCityUtils.getAllCity(), AllAreaBean.class);
    //获取所有的省份名字
    for (int i = 0; i < allAreaBean.getProvince().size(); i++) {
        ProvinceBean provinceBean = new ProvinceBean();
        provinceBean.setId(i);
        provinceBean.setName(allAreaBean.getProvince().get(i).getName());
        options1Items.add(provinceBean);

        //存放地区
        ArrayList<ArrayList<String>> listArea = new ArrayList<>();
        //存放城市名字
        ArrayList<String> listCity = new ArrayList<>();
        for (int j = 0; j < allAreaBean.getProvince().get(i).getCity().size(); j++) {
            if (allAreaBean.getProvince().get(i).getCity().size() == 1) {
                listCity.add("");
            } else {
                listCity.add(allAreaBean.getProvince().get(i).getCity().get(j).getName());
            }

            listArea.add((ArrayList<String>) allAreaBean.getProvince().get(i).getCity().get(j).getArea());
        }
        options3Items.add(listArea);
        options2Items.add(listCity);
    }
}

//PickerView选择器
OptionsPickerView pvOptions;

pvOptions = new OptionsPickerView(this);

 /**  * 添加城市信息  */  private void addCityMessage() {

        AreaUtils.getAllAreaPlace(options1Items,options2Items,options3Items);

        //三级联动效果
        pvOptions.setPicker(options1Items, options2Items, options3Items, true);
        //设置标题
        pvOptions.setTitle("选择城市");
        //设置监听
//        pvOptions.setSelectOptions(1, 1, 1);
        pvOptions.setOnoptionsSelectListener(new OptionsPickerView.OnOptionsSelectListener() {
            @Override
            public void onOptionsSelect(int i, int i1, int i2) {
                //返回的分别是三个级别的选中位置
                address = options1Items.get(i).getPickerViewText() + "省 " +
                        options2Items.get(i).get(i1) + "市 "
                        + options3Items.get(i).get(i1).get(i2) + "区";
                etAddress1.setText(address);
            }
        });


    }

case R.id.et_message_address1:
    pvOptions.show();
    break;
