根据屏幕分辨率使用适当的布局标记

Question

I've got a design list for 480x800, 1024x600, 1280x800. How do I ask android to use exact markup based on user screen's resolution ? As far as I know there're only abstract means(hdpi,xdpi) for solving resolution difference.

Answer 1

How do I ask android to use exact markup based on user screen's resolution ?

Talented developers don't do that. Talented developers realize that only a percentage of Android devices run at the resolutions listed above, just as desktop Web browsers do not run at only three window sizes. Talented developers work with the graphics designer to come up with fluid layouts for different screen sizes (eg, -normal , -large , -xlarge ), which may or may not run at the aforementioned resolutions. For example, there are devices with screen sizes ranging from 4" to 7" that run at 800x480, and there are devices with screen sizes from 4.5" to 10.1" running at 1280x800 (or thereabouts).

As far as I know there're only abstract means(hdpi,xdpi) for solving resolution difference.

-hdpi and -xhdpi have nothing to do with screen resolution. They are for screen density. Density is independent of resolution, and density is largely independent of size.

Answer 2

Create folder based screen width or height. For example

res/layout-w480dp, res/layout-w1024dp, res/layout-w1280dp

Or

res/layout-h800dp, res/layout-h600dp

Answer 3

Afaik, you can markup the layout folder by that is the minimum required screen resolution for the layout you can set one to min600 and one to min 800.

I think this markup scheme is supported in honeycomb and above and since these are tablets resolutions, they will have either anyway.
