不同屏幕尺寸的不同资源（以像素为单位）

Question

Is there a build-in functionality to provide different resources for different screen sizes ( in pixels )

What I found is a solution to separate them by dpi (using hdpi , ldpi , mdpi or sw320dp , sw720dp folders): http://developer.android.com/guide/topics/resources/providing-resources.html#AlternativeResources

But I don't care about densities!
My application mostly uses Bitmaps and Canvas, and all I want is to avoid scaling (and smoothing) of these bitmaps.

Have you tried using drawable-nodpi or raw for your bitmaps?

Answer 2

You can't specify by exact pixel sizes but there are 4 categories that you can use as modifiers to your layout folders. layout-small, layout-normal, layout-large, layout-xlarge.
