上一篇文章中了解到了Spinner的简单用法，知道了Spinner的数据源一般有两种形式。

XML文件和数组的方式。这次的内容主要是想在Spinner上实现省市区三级联动，话不多说了

直接上效果图吧！

城市信息我将他放在strings.xml文件中，具体就不给出了，信息太大了

主xml文件如下：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

        </TableRow>

        <EditText
