How to use a theme attribute as a color selector

I would like to define a list of color states for my text box, which by default uses primaryTextColor and colorAccent when it is activated. My definition:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:color="?android:attr/colorAccent" android:state_activated="true"/>

    <item android:color="?android:attr/textColorPrimary"/>

</selector>

This does not work (I always get red, which, I think, is an interpretation of id as argb color).

What can I do to indicate colors that depend on the theme?

I believe this is not possible from XML right now. I know that on the Android platform only support for theme attributes in resources with the ability to draw in Lollipop has been added, and it does not work below API 21. I believe that color resources have never received support.

!

final TypedArray attributes =
        itemView.getContext().obtainStyledAttributes(R.styleable.WowSdkSongViewHolder);
try {
    int colorAccent =
            attributes.getColor(R.styleable.WowSdkSongViewHolder_colorAccent, 0);
    final int textColorPrimary = attributes.getColor(
            R.styleable.WowSdkSongViewHolder_android_textColorPrimary, 0);

    title.setTextColor(new ColorStateList(
            new int[][] { ThemeUtils.ACTIVATED_STATE_SET, ThemeUtils.EMPTY_STATE_SET },
            new int[] { colorAccent, textColorPrimary }));
} finally {
    attributes.recycle();
}
