How to import external font/ typeface in ANDROID STUDIO?

Go on your Project: app-->src-->main

Create a assets folder like this:

|assets

    |-----------------fonts

        |-------------------font.ttf

|java

|res

AndroidManifest.xml

and then use

     Typeface face=Typeface.createFromAsset(getAssets(),"fonts/digital.ttf");
     txtV.setTypeface(face);

If you have custom font then use following code:

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

Also place your font file in assets/fonts folder and follow the instructions from here.

NOTE: You have to make asset folder by yourself
