1. Go to /res/values/colors.xml
2. Add the color to the colors.xml if not available as shown below
3. Go to /res/values/styles.xml
4. Add a new style and link it to the android:textAppearanceButton item style to the theme as shown below. Additionally, you can add button textSize.

    <color name="button_text_color">#AAAAAA</color>

        ...
    </style>

    <style name="ButtonText">
