No, you can't. Those values are static.

Or it's only possible to change font size in textView through setTextSize(value)?

Yes, that's actually the way you're supposed to dynamically change your TextViews sizes.-

TextView yourTextView = (TextView) findViewById(R.id.yourTextView);
yourTextView.setTextSize(20);

Keep in mind, however, that you should use the dimensions defined in your dimens.xml to do that.-

yourTextView.setTextSize(getResources().getDimension(R.dimen.dimen20));
