MenuItems, , MenuItem.setActionView() , , , MenuItem.setActionView(null)

public class MainFragment extends Fragment {

   private Menu mOptionsMenu;

   @Override
   public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
       mOptionsMenu = menu;
       inflater.inflate(R.menu.fragment_main, menu);
   }

   private void animateActionBarItem() {
       final MenuItem refreshItem = mOptionsMenu.findItem(R.id.action_refresh);
       refreshItem.setActionView(R.layout.actionbar_foo);
       refreshItem.getActionView()
            .animate()
            .setInterpolator(new AccelerateInterpolator())
            .setDuration(100L)
            .scaleX(2F)
            .scaleY(2F)
            .withEndAction(new Runnable() {

                @Override
                public void run() {
                    refreshItem.setActionView(null);
                }
            });
      }

}

XML R.layout.actionbar_foo

<?xml version="1.0" encoding="utf-8"?>
<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
    style="?android:attr/actionButtonStyle"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"

Take a look at my answer here . This is due to changes in the layout of the parent menu item, but if you look at my idea, you will understand how to animate the menu items.
