Supa TextView is a very simple class for Android extending TextView and letting changing the Font of your TextView right from the XML.
It is basically as simple as:
<org.supatextview.SupaTextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Supa TextView rocks!"
app:type_font="path_to_my_font_file"
/>
That is it! :)
