Android: View.setID(int id) programmatically - how to avoid ID conflicts?

Question

I\'m adding TextViews programmatically in a for-loop and add them to an ArrayList.

How do I use TextView.setId(int id)? What Integer ID do I come up wit

Answer 1

inspired by @dilettante answer, here's my solution as an extension function in kotlin:

/* sets a valid id that isn't in use */
fun View.findAndSetFirstValidId() {
    var i: Int
    do {
        i = Random.nextInt()
    } while (findViewById(i) != null)
    id = i
}
