Question

My question is quite simple:

In every of my textview, I am currently using the attribute

android:fontFamily=\"sans-serif-light\"

Answer 1

Dynamically you can set the fontfamily similar to android:fontFamily in xml by using this,

For Custom font:

 TextView tv = ((TextView) v.findViewById(R.id.select_item_title));
 Typeface face=Typeface.createFromAsset(getAssets(),"fonts/mycustomfont.ttf"); 
 tv.setTypeface(face);

For Default font:

 tv.setTypeface(Typeface.create("sans-serif-medium",Typeface.NORMAL));

These are the list of default font family used, use any of this by replacing the double quotation string "sans-serif-medium"
