<?xml version="1.0" encoding="utf-8"?>

           <dimen name="textsize">18sp</dimen>

Answer 2

Just create layout folders like layout, layout-small, layout-large, layout-xlarge then create values folders like values, values-ldpi, values-mdpi, values-hdpi, values-xhdpi. Then you can create values folder depending upon height or width and belongs to ldpi or mdpi i.e values-w360dp-mdpi or values-h600dp-mdpi. Then android automatically picks layout depending upon screen size and values on depending height or width.
