Use safe access to OnPreDrawListener.
Bug 32472451
It is important to remove an OnPreDrawListener from the correct
ViewTreeObserver. When a View is added to the view hierarchy, the
initial ViewTreeObserver is not active. The listener must then be
removed from the current OnPreDrawListener. When a View has been
removed from the hierarchy, it is important to remove the listener
from the orignal ViewTreeObserver.
