Adding Custom Styling

The UI you have now automatically applies the default style that is defined in the styles_def.xml file, shich is located in the res/raw folder. You can override this with custom settings in the styles_def.xml.

Paste this snippet between the <styles> tags:
<Style TargetType="Label" Key="CustomStyle" BasedOn="DefLabel" platform="android">
    <Setter Property="Foreground" Value="#F0AB00" />
    <Setter Property="FontFamily" Value="sans_serif" />
    <Setter Property="FontSize" Value="16" />
</Style>
This is a standard SAP style XML, which defines a custom label. To apply the custom style to your label, edit the config_phone.xml and set the style for the label:
<UIElement type="label">
    <!-- Assign the text to be displayed -->
    <P pid="text" value="Hello World! This is Extensibility!" />
    <P pid="style" value="CustomStyle" />
</UIElement>
