廢話不多說，直接上效果圖

1 匯入依賴庫

compile ‘com.github.open-android:citypicker:0.1.0’

2 地區定位

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //首先跳轉到列表頁面，通過startActivityForResult實現頁面跳轉傳值
 

        Intent intent = new Intent(MainActivity.this, CityListSelectActivity.class);
        startActivityForResult(intent, CityListSelectActivity.CITY_SELECT_RESULT_FRAG);
    }

    //接收選擇器選中的結果：
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super
 
.onActivityResult(requestCode, resultCode, data);
        if (requestCode == CityListSelectActivity.CITY_SELECT_RESULT_FRAG) {
            if (resultCode == RESULT_OK) {
                if (data == null) {
                    return;
                }
                Bundle bundle = data.getExtras();
                CityInfoBean cityInfoBean = (CityInfoBean) bundle.getParcelable("cityinfo"
 
);
                if (null == cityInfoBean)
                    return;
                //城市名稱
                String cityName = cityInfoBean.getName();
                //緯度
                String latitude = cityInfoBean.getLongitude();
                //經度
                String longitude = cityInfoBean.getLatitude();

                //獲取到城市名稱，經緯度值後可自行使用...
            }
        }
    }
}

3 省市區三級聯動

public class Main2Activity extends AppCompatActivity {
    private Button button;
    private CityPicker cityPicker;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);
        initCityPicker(Main2Activity.this);
        initView();
    }

    private void initView() {
        button = (Button) findViewById(R.id.choose);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                cityPicker.show();
            }
        });
    }

    private void initCityPicker(final Context context) {
        cityPicker = new CityPicker.Builder(context)
                .textSize(20)
                .backgroundPop(0xa0000000)
                .title("地址選擇")
                .titleBackgroundColor("#d9ead3")
                .titleTextColor("#000000")
                .confirTextColor("#00ff00")
                .cancelTextColor("#ff0000")
                .province("北京市")
                .city("北京市")
                .district("海淀區")
                .textColor(Color.parseColor("#000000"))
                .provinceCyclic(true)
                .cityCyclic(false)
                .districtCyclic(false)
                .visibleItemsCount(7)
                .itemPadding(10)
                .onlyShowProvinceAndCity(false)
                .build();
        cityPicker.setOnCityItemClickListener(new CityPicker.OnCityItemClickListener() {
            @Override
            public void onSelected(String... citySelected) {
                //省份
                String province = citySelected[0];
                //城市
                String city = citySelected[1];
                //區縣（如果設定了兩級聯動，那麼該項返回空）
                String district = citySelected[2];
                //郵編
                String code = citySelected[3];
            }
            @Override
            public void onCancel() {
                Toast.makeText(context, "已取消", Toast.LENGTH_LONG).show();
            }
        });
    }
}

去年9月份做專案一直在找這種demo，現在找到了很好的依賴庫，希望大家都可以使用哦
