How to change colors depending on the theme?

Question

Android

Such a situation, in the program, you can choose a theme for the program (roughly speaking holo light (by default) or holo dark), and, as I understand it, the colors specified in colors.xml cannot change depending on the selected theme. In the drawable, let's say the background color of the element is described, how to change it if holo dark is selected?

Answer 1

create links in attr.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
<attr name="titleColor" format="reference|color" />
<attr name="introColor" format="reference|color" />
</resources>

You create your themes with parent android:Theme or holo dark/light as desired already

<style name="AppTheme.MyDark" parent="android:Theme">
   <item name="titleColor">#FFFFFF</item>
   <item name="introColor">#FFFFFF</item>
</style>

<style name="AppTheme.MyLight" parent="android:Theme">
   <item name="titleColor">#000000</item>
   <item name="introColor">#004444</item>
</style

well, in the right ways

TextView
    android:id="@+id/quoteTitle"
    android:textColor="?titleColor"
    ...
</TextView>
