what right way use typeface in android? see many examples using custom xml tag text view. tried to set in java normal text view , works fine, reason use custom fields? when using custom typeface best add typeface /assets directory in project. lightweight following: textview customtypefacetextview = (textview) findviewbyid(r.id.customtypefacetextview); typeface customtypeface = typeface.createfromasset(getassets(), "custom_typeface.ttf"); customtypefacetextview.settypeface(customtypeface); just remember finding assets related current context if using custom fonts in fragment vs. activity want call getactivity().getassets() instead of getassets() . this reference quick tip : http://code.tutsplus.com/tutorials/customize-android-fonts--mobile-1601 additionally may more practical create class extends textview have more practical implementation custom font can used textview s want add custom font so: public class customtitletextview extends textview { pri
