使用CityPickerView框架实现三级联动

一，首先 在你的module.gradle中导入

dependencies {
   compile 'liji.library.dev:citypickerview:0.7.0'
}

二，上布局文件

<LinearLayout

    android:layout_marginTop="50dp"

    android:layout_width="match_parent"

    android:layout_height="wrap_content"

    android:orientation="horizontal">



    <TextView

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="地址："

        />



    <TextView

        android:id="@+id/address"

        android:background="#ff00"

        android:textColor="#000"

        android:layout_width="match_parent"

        android:layout_height="wrap_content" />



</LinearLayout>

三，看代码

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    private TextView mAddress;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        initView();

    }

    private void initView() {

        mAddress = findViewById(R.id.address);

        mAddress.setOnClickListener(this);

    }



    @Override

    public void onClick(View v) {

//        chooseArea(v);

        selectAddress();

    }


    private void selectAddress() {

        CityPicker cityPicker = new CityPicker.Builder(MainActivity.this)

                .textSize(14)

                .title("地址选择")

                .titleBackgroundColor("#FFFFFF")

//                .titleTextColor("#696969")

                .confirTextColor("#696969")

                .cancelTextColor("#696969")

                .province("北京市")

                .city("北京市")

                .district("朝阳区")

                .textColor(Color.parseColor("#000000"))

                .provinceCyclic(true)

                .cityCyclic(false)

                .districtCyclic(false)

                .visibleItemsCount(7)

                .itemPadding(15)

                .onlyShowProvinceAndCity(false)

                .build();

        cityPicker.show();

        //监听方法，获取选择结果

        cityPicker.setOnCityItemClickListener(new CityPicker.OnCityItemClickListener() {

            @Override

            public void onSelected(String... citySelected) {

                //省份

                String province = citySelected[0];

                //城市

                String city = citySelected[1];

                //区县（如果设定了两级联动，那么该项返回空）

                String district = citySelected[2];

                //邮编

                String code = citySelected[3];

                //为TextView赋值

                mAddress.setText(province.trim()+ city.trim()+ district.trim());

            }

        });

    }


}
