Finding all available styles defined by android platform themes

As stated in the “Applying Styles and Themes” article:

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.
