How to define dimens.xml for every different screen size in android?

Question

When supporting different screen sizes (densities) in Android often the focus is on creating different layouts for every possible screen. I.E.

Answer 1

we want to see the changes of required view size in different screens.

We need to create a different values folders for different screens and put dimens.xml file based on screen densities.

I have taken one TextView and observed the changes when i changed dimens.xml in different values folders.
