有关XML的点击状态背景图的设置

<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
<item android:state_window_focused="false"
android:state_enabled="true" android:drawable="@drawable/1" />
 <item android:state_window_focused="false"
 android:state_enabled="false" android:drawable="@drawable/2" /> 
<item android:state_pressed="true" android:drawable="@drawable/3" /> 
<item android:state_focused="true" android:state_enabled="true" android:drawable="@drawable/8" /> 
<item android:state_enabled="true" android:drawable="@drawable/7" />
 <item android:state_focused="true" android:drawable="@drawable/9" /> 
<item android:drawable="@drawable/0" />
 </selector>  

 主要常用的状态就这些了。整理下方便查阅。
