How to allow users to choose themes in android list view?

Question

I have a listview with two labels, title and subtitle. I want to have dark and light background as user options. Title has textAppearanceMedium and subtitle has textAppearanceSmall. I want the style, MyTheme.Dark to have white color text and MyTheme.Light to have black color text. Is there a way to define multiple textAppearance attribute for the same TextView widget?

<style name="MyTheme.Dark">
    <item name="android:windowBackground">@color/black</item>
    <item name="android:colorBackground">@color/black</item>
    <item name="android:background">@color/black</item>
    <item name="android:divider">@color/white</item>
        --cannot put textAppearance here since it is different for title and subtitle
    </style>

I'm a beginner with Android myself and I'm not sure if I'm not making an ass of myself here, but why don't you use the android:textColor property?

<style name="MyTheme.Dark">
    <item name="android:windowBackground">@color/black</item>
    <item name="android:colorBackground">@color/black</item>
    <item name="android:background">@color/black</item>
    <item name="android:divider">@color/white</item>
    <item name="android:textColor">@color/white</item>
</style>

I think best way is to have different layout xml for different colors and themes. Load the layout xml based on user choice. I do not like this but I have not found any alternatives.
