When I use different layouts to support different screens , should I use dp or px .

回答1:

Always use dp instead of px. There are three distinct but linked concepts to understand here: screen density (pixels per inch/centimeter, or commonly known as DPI from dots per inch in printers), physical screen size (in inches or centimeters) and number of pixels (also known as resolution, in pixels).

HERE is entire answer. Also read This.

回答2:

dp is best because it adjust itself according to the screen size of the device.It varies from device to device but less then pixel.So, always go for dp.
