title: LayoutTransition animation working for appear and dissappear, but not for change flags
body: <p>I am using layout transition, to trigger some animations when i set views to View.GONE and View.VISIBLE. </p>
  
  <p>it is working, there are 4 flags i am using to tell it what view to animate and when.
  these are:</p>
  
  <p>LayoutTransition.APPEARING-animate the view that is set to visible.
  LayoutTransition.CHANGE_APPEARING-when view is set to visible, animate other views in group.
  LayoutTransition.DISAPPEARING-animate the view that is set to gone.
  LayoutTransition.CHANGE_DISAPPEARING-when view is set to gone, animate other views in group.</p>
  
  <p>this is the code where i set the animations</p>
  
  <pre><code>    transition.setAnimator(LayoutTransition.APPEARING, changeOut2);
      transition.setAnimator(LayoutTransition.CHANGE_APPEARING, changeOut2);
      transition.setAnimator(LayoutTransition.DISAPPEARING, changeOut1);
      transition.setAnimator(LayoutTransition.CHANGE_DISAPPEARING, changeOut1);
  </code></pre>
  
  <p>my issue is that the change flags are not running the animations, but the others are working fine.</p>
  
  <p><strong>EDIT: added listener</strong></p>
  
  <p>Layout: There are three cardviews all in the same linear layout which has the LayoutTransition set to it. two are disappearing and the change_disappearing should run for the third cardview that remains in view.</p>
  
  <p>i have added a listener as follows:</p>
  
  <pre><code>transition.addTransitionListener(new LayoutTransition.TransitionListener(){
  
          @Override
          public void startTransition(LayoutTransition transition, ViewGroup container, View view, int transitionType) {
              switch(transitionType){
                  case LayoutTransition.APPEARING:
                      Log.i("anim", "APPEARING: "+view.toString());
                      break;
                  case LayoutTransition.DISAPPEARING:
                      Log.i("anim", "DISAPPEARING: "+view.toString());
                      break;
                  case LayoutTransition.CHANGE_APPEARING:
                      Log.i("anim", "CHANGE_APPEARING: "+view.toString());
                      break;
                  case LayoutTransition.CHANGE_DISAPPEARING:
                      Log.i("anim", "CHANGE_DISAPPEARING: "+view.toString());
                      break;
              }
          }
  
          @Override
          public void endTransition(LayoutTransition transition, ViewGroup container, View view, int transitionType) {
  
          }
      });
  </code></pre>
  
  <p>I am getting correct logs for APPEARING and DISAPPEARING, but no logs from either of the CHANGE flags, although i did get change logs initially for the parent so i set the following:</p>
  
  <pre><code>        transition.setAnimateParentHierarchy(false);
  </code></pre>
  
  <p>logs currently look like:</p>
  
  <pre><code>11-20 16:04:05.195  13612-13612//*PACKAGE*/ I/anim﹕ APPEARING: android.support.v7.widget.CardView{4289d238 V.E...C. ......ID 0,0-1080,512 #7f080057 app:id/home_card}
