make Colors.xml dynamic by referecing to theme

Question

How can I have colros defined in Colors.xml as dynamic?

My static colors.xml is like

<?xml version="1.0" encoding="utf-8"?> <resources> <color name="background">#ffffff</color> <color name="foreground">#000000</color> </resources>

By I need something like this which refers to colors defined in themes.xml. The way I defined colors in below doesn't work

<?xml version="1.0" encoding="utf-8"?> <resources> <color name="background">?theme_color_background</color> <color name="foreground">?theme_color_foreground</color> </resources>

I need this way to keep an old big project intact and just change theme. I referenced colors.xml like this in old project in a way like this:

<TextView textColor="@colors/foreground"/>

why not just call it directly from the textColor instead of wrapping it in color.xml — Rod_Algonquin

As i said its for old project and referenced colors.xml hundreds of time in different layouts — AVEbrahimi

You could what@ @Rod_Algonquin suggested and then do a global replace on textColor="@colors/foreground" — hoomi

You can not reference a color from your theme but you can reference a color from the android default color.xml to wrap it in your color.xml

sample:

<color name="black">@android:color/background_dark</color>
