KitKat color problems

Question

I have an app which is using a black background. I've been developing and testing it on Lollipop, yet minSDK is 19. When I use a KitKat device (or emulator), I run into a problem with the white text I see on my Lollipop device - it is black and thus invisible.

I define the text color like this:

<TextView
    android:id="@+id/list_header_date"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginLeft="6dp"
    android:text="27.02.2016"
    android:textColor="@color/text_primary"
    android:textSize="16dp"/>

Then, in (all) my styles.xml I have the following theme defined:

 <style name="AppTheme.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:textColorPrimary">@color/text_primary</item>
    <item name="android:background">@color/colorPrimary</item>
   </style>

In colors.xml, text_primary is defined like this:

<color name="text_primary">#FFFFFF</color>

Once again, on Lollipop I can see the text in pure perfect white, yet on KitKat it appears black. Where did I go wrong? In my opinion, since the TextView textcolor is defined explicitly to be text_primary it should work on across all SDK versions?!

Thanks to @zgc7009 this was resolved rather quickly:

As he was suggesting, the major overhaul of the design patterns in Lollipop requires some sort of AppCompat. Based on that and with a little bit of luck the following additions to the ../values-v19/styles.xml file made the text appear white in KitKat again:

 <style name="AppTheme.NoActionBar" parent="Theme.AppCompat.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:textColorPrimary">@color/text_primary</item>
</style>

Notice how I added a AppCompat parent to my custom style. I gotta be honest, I'm not exactly sure why it affects the color of the TextViews, if anyone knows feel free to edit or comment. Hope this helps a couple guys in the future.
