create another xml layout file for this resolution with smaller icons or suchlike

"By default, Android resizes your application layout to fit the current device screen. In most cases, this works fine. In other cases, your UI might not look as good and might need adjustments for different screen sizes. For example, on a larger screen, you might want to adjust the position and size of some elements to take advantage of the additional screen space, or on a smaller screen, you might need to adjust sizes so that everything can fit on the screen.

The configuration qualifiers you can use to provide size-specific resources are small, normal, large, and xlarge. For example, layouts for an extra large screen should go in layout-xlarge/. "

http://developer.android.com/guide/practices/screens_support.html#support

not without altering the original layout (that is, make it smaller on all screens) — Vincent Mimoun-Prat, Jul 27 '11 at 11:53

Done your project programatically use display metrics to get width and height $DisplayMetrics metrics; metrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(metrics); screenWidth = metrics.widthPixels; screenHeight = metrics.heightPixels;
