Android Theme详细

1.系统主题Theme列表

2.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：

颜色

<item name="colorForeground">@android:color/bright_foreground_dark</item><item name="colorForegroundInverse">@android:color/bright_foreground_dark_inverse</item><item name="colorBackground">@android:color/background_dark</item><item name="colorBackgroundCacheHint">?android:attr/colorBackground</item><item name="colorPressedHighlight">@color/legacy_pressed_highlight</item><item name="colorLongPressedHighlight">@color/legacy_long_pressed_highlight</item><item name="colorFocusedHighlight">@color/legacy_selected_highlight</item><item name="colorMultiSelectHighlight">@color/legacy_selected_highlight</item><item name="colorActivatedHighlight">@color/legacy_selected_highlight</item>

3、一些细化的style（特别是大量的控件的样式）定义在了styles.xml

themes.xml偏全局，styles.xml偏细化。
我直接贴出链接地址，大家查看：
https://github.com/CyanogenMod/android_frameworks_base/blob/cm-11.0/core/res/res/values/styles.xml

4、我们能做什么

两点说明：

我们可以根据这些样式改变系统控件的样式
但不是所有的样式我们都可以修改，比如AlertDialog，布局和一些属性都是写在硬编码中了，我们是无法修改的。

通过学习这些主题和样式，我们能准确的把握我们能定制哪些样式，哪些我们不能定制，是否需要重新写一套替代的UI控件。

这个在项目决策和进度评估上是非常重要的。
