As Chet Haase points out in DevBytes, https://www.youtube.com/watch?v=8MIfSxgsHIs, all of this will work but don't forget to add transientState flags.

From his code:

// Here's where the problem starts - this animation will animate a View object.
                    // But that View may get recycled if it is animated out of the container,
                    // and the animation will continue to fade a view that now contains unrelated
                    // content.
                    ObjectAnimator anim = ObjectAnimator.ofFloat(view, View.ALPHA, 0);
                    anim.setDuration(1000);
                    if (setTransientStateCB.isChecked()) {
                        // Here's the correct way to do this: if you tell a view that it has
                        // transientState, then ListView ill avoid recycling it until the
                        // transientState flag is reset.
                        // A different approach is to use ViewPropertyAnimator, which sets the
                        // transientState flag internally.
                        view.setHasTransientState(true);
                    }
                    anim.addListener(new AnimatorListenerAdapter() {
                        @Override
                        public void onAnimationEnd(Animator animation) {
                            cheeseList.remove(item);
                            adapter.notifyDataSetChanged();
                            view.setAlpha(1);
                            if (setTransientStateCB.isChecked()) {
                                view.setHasTransientState(false);
                            }
                        }
                    });
                    anim.start();
