我用我的XML文件到三纱厂。想改变微调的颜色，直到preSS下一个微调。
I'm using three spinners inside of my XML file. Want to change spinner color until press the next spinner.
这是我的XML我使用，
this is my xml i used,
<Spinner
android:id="@+id/spinner13"
android:drawSelectorOnTop="true"
android:background="@drawable/mybg"
android:layout_width="80dp"
android:layout_height="wrap_content"
android:textColor="#0000FF"
/>
<Spinner
android:id="@+id/spinner23"
android:drawSelectorOnTop="true"
android:background="@drawable/mybg"
android:layout_width="80dp"
android:layout_height="wrap_content"
android:textColor="#0000FF"
/>
<Spinner
android:id="@+id/spinner33"
android:drawSelectorOnTop="true"
android:background="@drawable/mybg"
android:layout_width="80dp"
android:layout_height="wrap_content"
android:textColor="#0000FF"
/>
这是mybg.xml
and this is mybg.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="@style/AppBaseTheme.Yellow"/>
<item android:state_selected="true" android:drawable="@style/AppBaseTheme.Yellow" />
</selector>
和风格：
</style>
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
</style>
<style name="AppBaseTheme.Yellow">
<item name="android:background">#FFAA00</item>
推荐答案
您可以更改mybg.xml如下图所示。
You can change mybg.xml as below.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:state_pressed="true">
<shape android:shape="rectangle">
<solid android:color="#FFAA00"/>
</shape>
</item>
<item
android:state_selected="true">
<shape android:shape="rectangle">
<solid android:color="#FFAA00"/>
</shape>
</item>
</selector>
如果要显示的箭头（>）。您可以更改如下文件mybg.xml。 九补丁文件可以在/Android/android-sdks/plataforms//data/res/spinner_default_holo_light.9.png找到。这个复制到你的绘制文件夹。
If want to show the arrow (">"). You can change your file mybg.xml as below. The nine-patch file can be found in /Android/android-sdks/plataforms//data/res/spinner_default_holo_light.9.png. Copy this to your drawable folder.
文件RES /绘制/ mybg.xml
File res/drawable/mybg.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:opacity="transparent">
<item
android:state_pressed="true">
<shape android:shape="rectangle">
<solid android:color="#AAFFAA00"/>
</shape>
</item>
<item
android:state_selected="true">
<shape android:shape="rectangle">
<solid android:color="#AAFFAA00"/>
</shape>
</item>
<item android:drawable="@drawable/spinner_default_holo_light"></item>
</layer-list>
