先上效果图：

 

就是一个类似微信qq那种item的shape。

 

即时上代码，少废话。

以下文件均为drawable文件夹下

以上为上中下的边框keyup keydown状态

以下是selector

文件：general_item_top_bg_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector
  xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true"
    android:drawable="@drawable/shape_general_item_top_bg_down"/>
    <item android:state_pressed="false"
    android:drawable="@drawable/shape_general_item_top_bg_up"/>  
</selector>

文件：general_item_center_bg_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector
  xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true"
    android:drawable="@drawable/shape_general_item_center_bg_down"/>
    <item android:state_pressed="false"
    android:drawable="@drawable/shape_general_item_center_bg_up"/>  
</selector>

文件：general_item_down_bg_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector
  xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true"
    android:drawable="@drawable/shape_general_item_down_bg_down"/>
    <item android:state_pressed="false"
    android:drawable="@drawable/shape_general_item_down_bg_up"/>  
</selector>

以上三个selector直接应用即可，文件名这么凸显了，相信众屌也能懂。

 

如有改进或错误之处，不怜赐教。
