Apps gridView checked Items

[Woman In Love]

Hi,

I have a gridView of items that represent options for answers to a question.

If the correct answer is chosen from the grid, I want it to be marked as correct (and the same for incorrect answer). Is there an easy way to this without changing the images programmatically?

Thank you.

Is changing the background colour an option? Say green for correct, and red for incorrect.
Or you could add a coloured border?
