Is it possible to use one Drawable instance as a background to multiple Views?

Question

Android

Hello everyone, there is a RelativeLayout with about 100 View elements. Each of these views is set (programmatically) to Drawable as a background. There are 4 background options in total, and I was thinking of creating 4 Drawable instances (one per option) and passing them to all Views.
Will this work correctly on all android versions (2.3 - 6)?
Thanks in advance!

As far as I remember, when you set a drawable via setBackgroundResource(), Android internally caches the loaded drawable, and reuses the created entity on subsequent calls. So you don't need to do anything extra.
