scaling app to bigger screens

I made a simple app with 开发者_StackOverflowrelative layout and dips. the problem is that on larger screens it just takes up a tiny part of the screen. is there a way to make it just one size and somhow scale to larger screens keping the layout intact?

You want to create a new folder layout-large and one layout-normal.

Copy your xml files that have fixed sizes to both folders, and adapt the size of the fixed-size Views to the larger screens (in layout-large). It will be approximately 50% larger. You can fine tune the sizes in the emulator. I found it easy to have two emulator instances, one with a normal screen and one with a large one so I can tweak the sizes and see the results in both layouts.

Also, consider that many of the larger screens retain the same resolution as the bigger phones (thus, having a much reduced dpi), so you may want to scale down images and copy them to a drawable-mdpi folder, keeping the originals in a drawable-hdpi folder.

Read the Android SDK section on Supporting Multiple Screens

This goes over what the best practices are for how to do this.
