<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/checkok" android:state_checked="true"></item>
<item android:drawable="@drawable/checkno" android:state_checked="false"></item>
</selector>
P.S:重点: android:button="@drawable/check_selector"
check_selector.xml中的checkok为CheckBox选中状态的图片,checkno为CheckBox未选中状态的图片.
