主界面xml文件
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" > <CheckBox android:layout_width="wrap_content" android:layout_height="wrap_content" android:button="@drawable/check_selector" android:checked="true" /> </RelativeLayout>
/res/drawable-hdpi/check_selector.xml
<?xml version="1.0" encoding="utf-8"?> <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.
