I think what's happening is that since you're overriding the default textcolor it isn't inheriting the other textcolor styles. Try creating a ColorStateList for it and setting the textColor attribute to it instead of to a color.
In a color file (eg res/color/example.xml):
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false" android:color="@color/disabled_color" />
<item android:color="@color/normal_color"/>
</selector>
then in your layout:
<TextView
android:text="whatever text you want"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="@color/example" />
Note, I haven't done this in a while and I'm typing a lot of this from memory, so it may need a little tweaking. The ColorStateList docs (linked above) have a more fleshed-out example for the color XML file.
