Android : Robotium： best way to target elements if view id is not usable?

Previously we use view id to get views on UI, however, the development team have changed the way they generated the id, so different views/elements on same screen may have same id. This change caused us not able to get the view using R.id.

in this situation, what is the best way to resolve this issue? I am current using 'index' to get the View, but I feel this might be fragile and easy to break when UI changes..

Needed some suggestions, thanks in advance!
