1、准备两张图片，并做好9.png

2、在drawable中定义spinner_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:state_pressed="true" android:drawable="@drawable/spinner_press" />  
    <item android:state_pressed="false" android:drawable="@drawable/spinner" />   
</selector>

3、style中定义

    
    <style name="spinner_style">
    <item name="android:background">@drawable/spinner_selector</item>
    <item name="android:paddingLeft">5dip</item>
    </style>

4、调用

<Spinner
    android:id="@+id/field_item_spinner_content"
    style="@style/spinner_style"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:animationCache="true"
    android:drawSelectorOnTop="true" />

5、在layout中定义simple_spinner_item.xml

<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@android:id/text1"
    android:paddingLeft="5dip"
    android:paddingRight="5dip"
    android:gravity="center_vertical"
    android:textColor="#808080"
    android:singleLine="true"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    />

6、java代码

ArrayAdapter < String > adapter = new ArrayAdapter < String > (mContext, R.layout.simple_spinner_item);
String level[] = getResources()
	.getStringArray(R.array.affair_level); //资源文件
for (int i = 0; i < level.length; i++) {
	adapter.add(level[i]);
}
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
