Android 内置皮肤
皮肤内置在程序里面的！其实可以不用我这么复杂的，直接每次换肤更改图片资源就可以。
那还是写上我的东西。
此处的xml借鉴郑涛的一篇关于xml详解一的一篇文章，写得很不错，大家也可以看看！
http://www.cnblogs.com/zhengtao/articles/1924940.html
基本思路是，每个控件在布局中写资源是drawable中的一个xml文件
而这个xml文件给每个控件分了4个level的图片
在程序中直接修改level就可以达到修改控件的图片资源！
贴上一个 button的buttonskin1.xml
1 <?xml version="1.0" encoding="utf-8"?>
2
3 <level-list xmlns:android="http://schemas.android.com/apk/res/android">
4
5 <item android:maxLevel="1" android:drawable="@drawable/button11" />
6
7 <item android:maxLevel="2" android:drawable="@drawable/button21" />
8
9 <item android:maxLevel="3" android:drawable="@drawable/button31" />
10
11 <item android:maxLevel="4" android:drawable="@drawable/button41" />
12
13 </level-list>
在布局文件里面 设置button的资源时候直接像引用图片那样android：background = "@drawable/buttonskin1"
程序里面通过修改level就可以修改它的bg button1.getBackground().setLevel(level);
之所以这样写是在 再添加其他的主题时候只需要在button里面再添加个level就可以 再弄个监听器触发一下
布局文件main.xml：
1 <?xml version="1.0" encoding="utf-8"?>
2
3 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

5 android:orientation="vertical"

67 button1.getBackground().setLevel(level);
68 button2.getBackground().setLevel(level);
69 button3.getBackground().setLevel(level);
70 button4.getBackground().setLevel(level);
71 button5.getBackground().setLevel(level);
72 button6.getBackground().setLevel(level);
73 button7.getBackground().setLevel(level);
74 button8.getBackground().setLevel(level);
75 image.getDrawable().setLevel(level);
76 }
77 }
再最下面的4个按钮添加监听器 分别对应4中皮肤！
