android - Padding in different phones -

say add linear layout top padding of 20. mean layout rendered 20 pixels of padding in phones? or scale according height/width/density of phone?

in java code going pixels on devices. if want make density respected (like using 20dp or 20dip) can use:

float density = context.getresources().getdisplaymetrics().density; setpadding(20 * density, blah, blah, blah); 

that density var 1.0 on medium phones, or more or less depending on density of screen.
