//1.create different dimens.xml in different resource folders as below 

 res/values-ldpi/dimens.xml
 res/values-mdpi/dimens.xml
 res/values-hdpi/dimens.xml

 //Then Android will decide which file to use. 

//2.Create  dimensions values in respective dimens.xml file according to the need as below


 <!-- in values-ldpi/dimens.xml -->
 <dimen name="textSize">25dip</dimen>

// and..

 <!-- in values-mdpi/dimens.xml -->
 <dimen name="textSize">20dip</dimen>

// etc. 
// 3.Don't care about resolution Android will take care of which resource to fetch.
// 4.Mention size in  dp instead of pixels.

you define you layout and put it under

res/layout-Qualifier/my_layout.xml
where Qualifier could be one or more of the following

size : small, normal, large

density: ldpi,mdpi, hdpi.

For example layout for large screen with high density would be res/layout-hdpi-large/my_layout.xml

For full list of attributes see answer above

You can use different units to have the dimensions adapt to the screen.

Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), mm (millimeters).
