1.添加依赖
implementation 'liji.library.dev:citypickerview:3.1.12'
2.Activity 设置
private CityPickerView mPicker = new CityPickerView();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.delivery_add_new);
mPicker.init(this); //必须！ 初始化城市数据
……
}
3.设置点击事件
deliveryAddDistrict.setOnClickListener(this);
@Override
public void onClick(View view) {
if (view == deliveryAddDistrict){ //地区联动选择
//添加默认的配置，可以自己修改
CityConfig cityConfig = new CityConfig.Builder()
.province("北京") //设置默认显示省份
.build();
mPicker.setConfig(cityConfig);
//监听选择点击事件及返回结果
mPicker.setOnCityItemClickListener(new OnCityItemClickListener() {
@Override
public void onSelected(ProvinceBean province, CityBean city, DistrictBean district) {
//省份
if (province != null && city != null && district != null) {
deliveryAddDistrict.setText(province.toString()+" "+city.toString()+" "+district.toString());
}
}
@Override
public void onCancel() {
ToastUtils.showLongToast(DeliveryAddNewActivity.this, "已取消");
}
});
//显示
mPicker.showCityPicker( );
}
