使活动规模在所有设备上都相同吗？ -安卓

Question

Can what is described in the title be done? I mean the whole activity just scales up or down to take up the same percentage of the device screen, so buttons and everything else, all views, all free space, margins, grow on a big screen. Is this what "dp" is? So setting all measurements in dp where possible would do this?

Thanks.

Answer 1

dp is the unit you have to use in your dimensions, so everything scales depending on the density of the device. But probably you also need to take care of the actual physical size of the screen, the with/height ratio, etc...
