     IMPORTANT NOTE:
       In summary to change the text size for a Spinner either:

      Create a custom TextView layout.
      Change the text size with the android:textSize attribute.
      Change the text color with android:textColor in the new style file.
      
      Or:
      
      Create a custom style.
      Use android:TextAppearance.Widget.TextView.SpinnerItem as the parent style.
      Change the text size with the android:textSize attribute.
      
      Or:
      
      Customize the theme
