Styles and Themes Styles in Android share a similar philosophy to cascading stylesheets in web design - they allow you to separate the design from the content. For example, by using a style, you can take this layout XML:
And turn it into this:
Defining Styles To create a set of styles, save an XML file in the res/values/ directory of your project. The name of the XML file is arbitrary, but it must use the .xml extension and be saved in the res/values/ folder. The root node of the XML file must be . <style name="CodeFont" parent="@android:style/TextAppearance.Medium" > match_parent wrap_content #00FF00 monospace
Inheritance Inheriting from platform styles: <style name="GreenText" parent="@android:style/TextAppearance" > #00FF00
Inheriting from styles that you've defined yourself: <style name="CodeFont.Red" > #FF0000
<style name="CodeFont.Red.Big" > 30sp
Applying Styles and Themes to the UI There are two ways to set a style: ● To an individual View, by adding the style attribute to a View element in the XML for your layout. ● Or, to an entire Activity or application, by adding the android:theme attribute to the or element in the Android manifest.
Apply a theme to an Activity or application
<style name="CustomTheme" parent="android:Theme.Light" > @color/custom_theme_color @color/custom_theme_color
