给控件设置各种小动画效果

 rootView.findViewById(R.id.btnAnimMe).setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View arg0) {
                //    AlphaAnimation aa = new AlphaAnimation(0, 1);
                //    aa.setDuration(1000);
                //    arg0.startAnimation(aa);
                    arg0.startAnimation(AnimationUtils.loadAnimation(getActivity(), R.anim.aa));
                }
            });
