android - 查找由 android 平台主题定义的所有可用样式

Question

在几个 android 样式教程中使用了我在 android.R.style.* 样式 (http://developer.android.com/reference/android/R.style.html) 中找不到的父样式元素。

一些示例来自 http://android-developers.blogspot.com/2011/04/customizing-action-bar.html操作栏文章。 Nick 使用如下父样式:

<style name="MyDropDownNav" parent="android:style/Widget.Holo.Light.Spinner.DropDown.ActionBar">
...
</style>

或

<style name="MyActionBarTabStyle" parent="android:style/Widget.Holo.Light.ActionBarView_TabView">
...
</style>

这些父样式从何而来？是否可以列出所有可用的父样式？

谢谢。

如 "Applying Styles and Themes" 中所述文章:

The Android platform provides a large collection of styles and themes that you can use in your applications. You can find a reference of all available styles in the R.style class. To use the styles listed here, replace all underscores in the style name with a period. For example, you can apply the Theme_NoTitleBar theme with "@android:style/Theme.NoTitleBar".

The R.style reference, however, is not well documented and does not thoroughly describe the styles, so viewing the actual source code for these styles and themes will give you a better understanding of what style properties each one provides. For a better reference to the Android styles and themes, see the following source code:

• Android Styles (styles.xml)
• Android Themes (themes.xml)

These files will help you learn through example. For instance, in the Android themes source code, you'll find a declaration for <style
name="Theme.Dialog">. In this definition, you'll see all of the properties that are used to style dialogs that are used by the Android framework.
