Android中使用Spinner来实现图标文字并存的二级联动

安卓中实现二级联动的样子

效果图：



实现思路：

通过spinner控件，在java代码中去把你要展示的信息存放到map集合中，接着设置适配器，设置省的监听事件，根据键去拿值，再次设置适配器

代码：

activity_spinner.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<!--TextView标签与Spinner标签-->
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="省份："
/>
<Spinner
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/s_spinner_spinner1"
></Spinner>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="城市："
/>
<Spinner
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/s_spinner_spinner2"
></Spinner>
</LinearLayout>SpinnerActivity:

//适配器中的参数：
