I'm adding Buttons programmatically and the number of Buttons depends on some conditions. To add rules for RelativeLayout.LayoutParams that Buttons be aligned to the top of each other I need to set their IDs. All the answers from 2-3 years ago say that setId(int) is okay (e.g. setId(1)) but now it's forbidden (UPD. it's not ok only with int literals. With int variables everything is ok. Wonder why). How to do it nowadays?
