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.

For "android:style/Widget.Holo.Light.ActionBarView_TabView" see:http://developer.android.com/reference/android/R.style.html#Widget_Holo_Light_ActionBar_TabView...and note the API level it was introduced at!

For "android:style/Widget.Holo.Light.Spinner.DropDown.ActionBar" try:http://developer.android.com/reference/android/R.style.html#Widget_Holo_Light_DropDownItem_Spinner

The latter is just my best guess - I can't get the list to actually drop down.

Parent attribute is a optional one while creating your own themes or styles.Basically parent attributes are used for inheriting the styles which are already defined in the platform itself.

If we wish to inherit a theme or style and overwriting some features, we can use parent attribute.

Here's a link for the all available platform defined styles.

And one more tip :

If you want to inherit your own style that you created by yourself means follow this example to inherit.

    <style name="MyDropDownNav.Red">        <item name="android:textColor">#FF0000</item>    </style>
