It would be useful for a transition to declare not just which targets it wants to be run on, but also which targets it wants to avoid. For example, you may not want to animate the items of a ListView, or some other specific target in the view hierarchy. This change adds various exclude*() methods which make it possible to alter a transition to automatically ignore specific views, ids, or classes in the hierarchy. Issue #10692794 Transitions: Need API for excluding targets Change-Id: If38025cdbee537a545e5a4268cbbd763af4622c5
