Android UI控件之Spinner兑现省市区三级联动

Android UI控件之Spinner实现省市区三级联动
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" android:focusableInTouchMode="false" > <TableLayout android:id="@+id/tableLayout1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:paddingTop="20px" android:stretchColumns="1" > <TableRow android:id="@+id/tableRow1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingTop="10px" android:scrollbarAlwaysDrawVerticalTrack="false" > <TextView android:id="@+id/province_text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="省份：" > </TextView> <Spinner android:id="@+id/province_spinner" android:layout_width="wrap_content" android:layout_height="wrap_content" > </Spinner> </TableRow> <TableRow android:id="@+id/tableRow2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingTop="10px" android:scrollbarAlwaysDrawVerticalTrack="false" > <TextView android:id="@+id/city_text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="城市：" > </TextView> <Spinner android:id="@+id/city_spinner" android:layout_width="wrap_content" android:layout_height="wrap_content" > </Spinner> </TableRow> <TableRow android:id="@+id/tableRow3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingTop="10px" android:scrollbarAlwaysDrawVerticalTrack="false" > <TextView android:id="@+id/county_text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="县城镇：" > </TextView> <Spinner android:id="@+id/county_spinner" android:layout_width="wrap_content" android:layout_height="wrap_content" > </Spinner> </TableRow> <EditText android:id="@+id/display_edit" android:layout_width="wrap_content" android:layout_height="wrap_content" android:focusableInTouchMode="false" android:hint="输出结果" android:paddingTop="10px" > </EditText> </TableLayout></RelativeLayout>MainAcitivty问价如下：
