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：

[java] view
plain copy

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout 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: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">

<TextView

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" />

</RelativeLayout>

MainActivity:

[java] view
plain copy

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);

}

});

}

});

}

}
