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

I use:

public synchronized int generateViewId() {
    Random rand = new Random();
    int id;
    while (findViewById(id = rand.nextInt(Integer.MAX_VALUE) + 1) != null);
    return id;
}

By using a random number I always have a huge chance of getting the unique id in first attempt.
