How can I change font size in PreferenceScreen

Answer 1

Have a look at my answer to this: Android PreferenceScreen title in two lines.

You can also change the font itself if you want. Just add this:

Typeface myTypeface = Typeface.createFromAsset(textView.getContext().getAssets(),"fonts/your_font_name.ttf");
    if (textView != null) {
        textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, textView.getContext().getResources().getDimension(R.dimen.text_size_from_dimen));
        textView.setTypeface(myTypeface);
    }
