I'm not sure if I have the correct query and that's why I can't seem to find anything on this topic, but I am trying to add a graphical border to a view, let's say textView or button or even a progressBar.
To my knowledge you're supposed to take a texture or a small piece of the overall border and then draw it onto or near the view so you don't have to save 100 different sizes of the image (is this correct)? 
It's a pretty simple border, so I might be able to get away with just drawing it with colors (which I know how to do), but I would like to know how I would apply a texture like this to a view.
Any help is appreciated - even a related query/tutorial that I can go follow!
