【基于最新的Android4.4的源码分析】
每家公司或者每个移动团队无不想开发出一套自己的UI框架，融入自己的设计和特性，这必然会去修改android的ui。
所以，学习和理解android的UI设计是最基础和非常有必要的。
android
ui设计最重要的就是主题和样式。
1、位置
在Android的frameworks/base/core/res/res/values目录下有一下几个文件：
|
1
2
3
4 |
themes.xmlthemes_device_defaults.xmlstyles.xmlstyles_device_defaults.xml |
分别定义了各种系统Theme，Style。
2、主题Theme
主要关注themes.xml,themes_device_defaults.xml两个文件。
themes.xml定义了android低版本的theme和Holo
theme，themes_device_defaults.xml定义了DeviceDefault主题（继承自Holo主题），实际上就是在Holo主题上定制主题（For厂商）。
系统如何去选择默认的主题呢？

/**frameworks/base/core/java/android/content/res/Resources.java*//** @hide */public static int selectDefaultTheme(int
curTheme, int
targetSdkVersion) { return
selectSystemTheme(curTheme, targetSdkVersion, com.android.internal.R.style.Theme, com.android.internal.R.style.Theme_Holo, com.android.internal.R.style.Theme_DeviceDefault);} /** @hide */public
static int selectSystemTheme(int
curTheme, int
targetSdkVersion, int
orig, int
holo, int
deviceDefault) { if
(curTheme != 0) { return
curTheme; } if
(targetSdkVersion < Build.VERSION_CODES.HONEYCOMB) { // < 11 return
orig; } if
(targetSdkVersion < Build.VERSION_CODES.ICE_CREAM_SANDWICH) { // < 14 return
holo; } return
deviceDefault;} |
当<11时，使用以前低版本主题;当>=11&&<14，使用Holo主题;>14的时候，使用DeviceDefault主题。
方便理解，下面把目前所有的版本号列出来，也顺便温习一下android的历史：

3、系统主题Theme列表
系统默认大的主题是三种：Theme,Theme.Holo,Theme.DeviceDefault,
但是实际上在此基础系统还定义了大量的派生主题，最典型的是对应的Light主题。
除此之外，还有很多，在此一一列出，打字太痛苦了，我贴出截图：
了解android系统定义的主题之后，我们就可以根据实际情况在自己的应用中使用这些主题，但是如果想修改主题的某些内容，需要进一步深入。
4、详解每个主题中定义item分类
一个完整的主题应该定义哪些内容呢，以Theme为例，如下：
1）颜色
