<?xml version="1.0" encoding="utf-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- 默认时的背景背景 -->
<item android:drawable="@drawable/pic1" />
<!-- 没有焦点时的背景图片 -->
<item android:state_window_focused="false" android:drawable="@drawable/pic1" />
<!-- 非触摸模式下获得焦点并单击时的背景图片 -->
<item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/pic2" />
<!-- 触摸模式下单击时的背景图片 -->
<item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/pic3" />
<!-- 选中时的图片背景 -->
<item android:state_selected="true" android:drawable="@drawable/pic4" />
<!-- 获得焦点时的图片背景 -->
<item android:state_focused="true" android:drawable="@drawable/pic5" />

在listView中配置android:listSelector="@drawable/list_item_bg"或者在item中添加android:background="@drawable/list_item_bg"即可实现,或者在java代码中使用Drawable drawable = getResources().getDrawable(R.drawable.list_item_bg);,listView.setSelector(drawable);。可能出现列表出现黑的情况,加上android:cacheColorHint="@android:color/transparent"
