android 点击效果动画增强

1.使用开源库制作view 的放大+透明度的动画

animate(v).scaleX(factor).scaleY(factor).alpha(0);

2. 设计回调接口

    public interface ClickAnimation {        public void onClick(View v);    }

3. 在view 的onclick 的处理中增加动画的调用，并把以前的onclick事件处理作为回调加入到animation中，在动画完成后回调处理函数。在动画结束时将view的状态恢复到原始状态

    private void animateClickView(final View v, final ClickAnimation callback) {        float factor = 2;        animate(v).scaleX(factor).scaleY(factor).alpha(0).setListener(new AnimatorListenerAdapter() {            @Override            public void onAnimationEnd(Animator animation) {                ViewHelper.setScaleX(v, 1);                ViewHelper.setScaleY(v, 1);                ViewHelper.setAlpha(v, 1);                if (callback != null) {                    callback.onClick(v);                }                super.onAnimationEnd(animation);            }        });    }

4. TODO：可以依据这个结构，添加更多动画效果。比如摇摆/震动等

实现效果参见youku视频：
