1. Define one or more themes in themes.xml and set the definitions of your styles there.
2. Define custom attributes, a.k.a. custom styles, in attrs.xml.
3. Describe what the values of your custom styles are in styles.xml.

But you will need read more about the attrs.xml

Instead, we are referring to the value of some other attribute – activatedBackgroundIndicator – from our inherited theme. Whatever the theme defines as being the activatedBackgroundIndicator is what our background should be.
