一切从简_e156
最近在项目当中有一个滑动验证码动画效果要实现,刚开始看到这个效果感觉还是可以的,但是要实现起来觉得有点麻烦,我想大家一定都和我一样拿到这个需求一定是一顿谷歌,百度啥的,但是搜索了很久都没找到相似的效果,又催的急没办法,卷起袖子干吧,就开始自己造轮子的过程,在做这个需求的过程中,还是很有收获的比如说复习了下高中的函数知识,我想大家都和一样高中的数学知识应该都忘的差不多了吧,反正我是忘的差不多了,废话不多说了,直接上代码,里面使用到了的图片,大家可以自己搞一点图片进去试试
下图是我截取的一部分,效果就是这样

这个布局也是一个关键的一个地方,图片大家或者背景大家可以自己设置下
