其实这个问题一直困扰着我，后来终于解决了。其实很简单看下面的截图，不好意思，截图有点模糊：
1、listView控件 <ListView android:id="@+id/contact_listview" android:layout_width="wrap_content" android:layout_height="400dip" android:divider="#b9b9b9" android:dividerHeight="1px" android:cacheColorHint="#00000000" android:listSelector="@drawable/list_selector" android:headerDividersEnabled="true"> </ListView>
如果是继承ListActivity的话，则可以这样设置。
view plain copy to clipboard print ? this .getListView().setSelector(getResources().getDrawable(R.drawable.list_selector));2、在drawable文件夹中见一个list_selector.xml文件，如果什么内容都不定，只是用来把系统自带的给覆盖掉，在这里我们添 加上我要添加的小图片，其中list_item_color.png只是一张只有10*10透明的图片，list_item_sel_color也是一 张10*10的浅蓝色的图片。
list_item_sel_color:
list_item_color:
view plain copy to clipboard print ? <?xml version= "1.0" encoding= "UTF-8" ?> <selector xmlns:android="http://schemas.android.com/apk/res/android" > Non focused states <item android:state_focused="false" android:state_selected= "false" android:state_pressed= "false" android:drawable= "@drawable/list_item_color" /> <item android:state_focused="false" android:state_selected= "true" android:state_pressed= "false" android:drawable= "@drawable/list_item_sel_color" /> Focused states <item android:state_focused="true" android:state_selected= "false" android:state_pressed= "false" android:drawable= "@drawable/list_item_sel_color" /> <item android:state_focused="true" android:state_selected= "true" android:state_pressed= "false" android:drawable= "@drawable/list_item_sel_color" /> Pressed <item android:state_pressed="true" android:drawable= "@drawable/list_item_sel_color" /> </selector>以上就可以完成背景的设置 效果如下：
