Combining screen height with different resolution layout files?

I set up my Android application to support different screen resolutions (ldpi, mdpi, hdpi, xhdpi, ...) and that seems to be working as it should. Different screen heights on the other hand are not scaling correctly: I optimized my design to fit on the small screens (of the default Android Studio emulators) which means that there is a lot of empty space on longer devices. Is there any way to combine screen resolutions (xhdpi, ...) with screen lenght (long, ...)? If this is not possible at all I would really appreciate alternative methods of layout scaling in order to fix my problem. I currently use dp and RelativeLayouts only. Thanks in advance.

RL in the picture below represents RelativeLayouts.

I would suggest using multiple nested linear layouts while specifying layout weights to scale components on all kinds of displays (see this guide for example). Tip: You can use empty views to create dynamic spaces. Also in some cases it is useful to specify portrait and landscape layouts separately (see this guide) although then you have to manage some duplicate code.
