Android 地址选择器，实现省市区三级联动

最近项目里面用到了一个地址选择器，实现现在主流的WheelView滑动选择，整理了下，做了个Demo.废话不多说，直接上代码：

主布局：

 "1.0" encoding="utf-8"?>
 "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:paddingBottom="@dimen/activity_vertical_margin"
     android:paddingLeft="@dimen/activity_horizontal_margin"
     android:paddingRight="@dimen/activity_horizontal_margin"
     android:paddingTop="@dimen/activity_vertical_margin"
     tools:context="com.example.user.myapplication.MainActivity">


         android:id="@+id/select_address_tv"
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:gravity="center"
         android:textSize="15sp"
         android:text="选择地址" />

MainActivity:

 package com.example.user.myapplication;

 import android.support.v7.app.AppCompatActivity;
 import android.os.Bundle;
 import android.view.Gravity;
 import android.view.View;
 import android.widget.TextView;
 import android.widget.Toast;

 public class MainActivity extends AppCompatActivity {
     private TextView select_address_tv;

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

         select_address_tv= (TextView) findViewById(R.id.select_address_tv);
         select_address_tv   .setOnClickListener(new View.OnClickListener() {
             @Override
             public void onClick(View v) {
                 ChangeAddressPopwindow mChangeAddressPopwindow = new ChangeAddressPopwindow(MainActivity.this);
                 mChangeAddressPopwindow.setAddress("广东", "深圳", "福田区");
                 mChangeAddressPopwindow.showAtLocation(select_address_tv, Gravity.BOTTOM, 0, 0);
                 mChangeAddressPopwindow
                         .setAddresskListener(new ChangeAddressPopwindow.OnAddressCListener() {

                             @Override
                             public void onClick(String province, String city, String area) {
                                 // TODO Auto-generated method stub
                                 Toast.makeText(MainActivity.this,
                                         province + "-" + city + "-" + area,
                                         Toast.LENGTH_LONG).show();
                                 select_address_tv.setText(province + city + area);
                             }
                         });

     }
 }
