给控件设置各种小动画效果

1  rootView.findViewById(R.id.btnAnimMe).setOnClickListener(new View.OnClickListener() {
2                 @Override
3                 public void onClick(View arg0) {

6                 //    arg0.startAnimation(aa);
7                     arg0.startAnimation(AnimationUtils.loadAnimation(getActivity(), R.anim.aa));
8                 }
9             });
