效果图：

这里写图片描述

一、添加依赖：

project：build.gradle

allprojects {    repositories {        jcenter()        maven { url "https://jitpack.io"}    }}

app：build.gradle

    compile 'com.alibaba:fastjson:1.1.55.android'    compile('com.github.gzu-liyujiang.AndroidPicker:WheelPicker:1.5.4') {        exclude group: 'com.android.support'    }//    compile('com.github.gzu-liyujiang.AndroidPicker:FilePicker:1.5.4') {//        exclude group: 'com.android.support'//    }//    compile('com.github.gzu-liyujiang.AndroidPicker:ColorPicker:1.5.4') {//        exclude group: 'com.android.support'//    }

布局：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    tools:context="com.example.lenovo.mypicker.MainActivity">    <TextView        android:id="@+id/tv_address"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:gravity="center"        android:text="你选择的地址"        android:textColor="@color/colorPrimary"        android:textSize="25sp" />    <Button        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:onClick="onAddressPicker"        android:text="地址选择（包括省级、地级、县级）" /></LinearLayout>

MainActivity

public class MainActivity extends AppCompatActivity {    private TextView tvAddress;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        tvAddress = ((TextView) this.findViewById(R.id.tv_address));    }    public void onAddressPicker(View view) {        AddressPickTask task = new AddressPickTask(this);//        task.setHideProvince(true);//隐藏省，显示市、县//        task.setHideCounty(true);//隐藏县，显示省、市        task.setCallback(new AddressPickTask.Callback() {            @Override            public void onAddressInitFailed() {                ToastUtil.showToast(MainActivity.this, "数据初始化失败");            }            @Override            public void onAddressPicked(Province province, City city, County county) {                String address;                if (county == null) {                    address = province.getAreaName() + city.getAreaName();                    ToastUtil.showToast(MainActivity.this, province.getAreaName() + city.getAreaName());                } else {                    address = province.getAreaName() + city.getAreaName() + county.getAreaName();                    ToastUtil.showToast(MainActivity.this, province.getAreaName() + city.getAreaName() + county.getAreaName());                }                tvAddress.setText(address);            }        });        //以下几种格式显示效果相同//        task.execute("广东省", "深圳市", "龙岗区");//设置默认//        task.execute("广东", "深圳", "龙岗");//设置默认//        task.execute("广东省", "深圳", "龙岗");//设置默认//        task.execute("广", "深圳", "龙岗");//设置默认//        task.execute("广", "深", "龙岗");//设置默认        task.execute("广", "深", "龙");//设置默认    }}

AddressPickTask
