效果圖：

  一、新增依賴

dependencies {
    ·····
    implementation 'liji.library.dev:citypickerview:0.7.0'
}

二、這裡就不在介紹佈局檔案了，直接演示實現程式碼：

package com.example.weicy.myapplication;

import android.content.Context;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import 
 
android.view.View;
import android.view.inputmethod.InputMethodManager;
import android.widget.TextView;
import com.lljjcoder.citypickerview.widget.CityPicker;

public class MainActivity extends AppCompatActivity {
    private TextView mSubmitTv;
    private TextView new_address_area;

    @Override
protected void 
 
onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mSubmitTv = (TextView) findViewById(R.id.submit_tv);
        new_address_area = (TextView) findViewById(R.id.new_address_area);
        mSubmitTv.setOnClickListener(new 
 
View.OnClickListener() {
            @Override
public void onClick(View v) {
                //判斷輸入法的隱藏狀態
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                if (imm.isActive()) {
                    imm.hideSoftInputFromWindow(v.getWindowToken(),
                            InputMethodManager.HIDE_NOT_ALWAYS);
                    selectAddress();//呼叫CityPicker選取區域
}
            }
        });
    }

    private void selectAddress() {
        CityPicker cityPicker = new CityPicker.Builder(MainActivity.this)
                .textSize(14)
                .title("地址選擇")
                .titleBackgroundColor("#FFFFFF")
                .confirTextColor("#696969")
                .cancelTextColor("#696969")
                .province("江蘇省")
                .city("常州市")
                .district("天寧區")
                .textColor(Color.parseColor("#000000"))
                .provinceCyclic(true)
                .cityCyclic(false)
                .districtCyclic(false)
                .visibleItemsCount(7)
                .itemPadding(10)
                .onlyShowProvinceAndCity(false)
                .build();
        cityPicker.show();
        //監聽方法，獲取選擇結果
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];
                //為TextView賦值
new_address_area.setText(province.trim() + "-" + city.trim() + "-" + district.trim());
            }
        });
    }
}
