LibGDX 1.0 provides what you need : Viewports.

The idea is to work with a known virtual screen size and then have it resized to fit your real screen.

I recommend you to give a look at this tutorial that explains how to handle game screen resizing with Viewports : https://github.com/libgdx/libgdx/wiki/Viewports
