LayoutTransition used to depend on child views being added/removed or shown/hidden in the transition container. These evens would trigger animations to fade the child view as well as those to animate the side-affected changes to sibling views. This CL enables a new feature in LayoutTransition that enables animating any changes to the layout of the children in the container whenever a layout occurs. For example, you can change the LayoutParams of a child view and call requestLayout() to automatically animate those changes. This capability is not enabled by default. To enable, call the new LayoutTransition.enableTransitionType(LayoutTransition.CHANGING) method. Change-Id: I4d07a3b36245353b2151f0dca4f75080ab6a4592
