As far as I m aware  you can t declare custom fonts in xml or themes  I usually just make custom classes extending textview that set their own font on instantiation and use those in my layout xml files   ie   public class Museo500TextView extends TextView       public Museo500TextView Context context  AttributeSet attrs            super context  attrs                 this setTypeface Typeface createFromAsset context getAssets     path to font ttf               and   lt my package views Museo900TextView         android id    id dialog error text header          android layout width  190dp          android layout height  wrap content          android gravity  center horizontal          android textSize  12sp    gt
