How can I change font type in Android TextView?
To add to Ted Hopp's answer, if you are looking at a custom font for your TextView, in your Activity from where you reference the TextView, use this code example:
Typeface blockFonts = Typeface.createFromAsset(getAssets(),"ROBOTO-MEDIUM_0.TTF");
TextView txtSampleTxt = (TextView) findViewById(R.id.your_textview_id);
txtSampleTxt.setTypeface(blockFonts);
Although, before you can use this, you will need to copy the font/s of your choice in the assets folder.
You can also look at one of my answer on SO which has a couple of websites you can use to download fonts. They are:
