Create a dimens.xml file in your res directory with contents similar to this:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <dimen name="some_text_size">18dp</dimen>
</resources>

Then instead of referencing it like @string/blah, use @dimen/blah.

Answer 2

Use this as your XML resource and call it from where ever you want...

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <dimen name="textview_height">25dp</dimen>
    <dimen name="textview_width">150dp</dimen>
    <dimen name="ball_radius">30dp</dimen>
    <dimen name="font_size">16sp</dimen>
</resources>

Then call this in code:

Resources res = getResources();
float fontSize = res.getDimension(R.dimen.font_size);
