本教程是基于csdn作者教程补充的，里面有一些细节我整好了，有几个地方不太对劲。不知道咋回事
导入进去里面的demo就可以打开食用。
item预制体实现
在画布下面添加空对象，然后添加Horizontal layout group,
添加 UI Student Info脚本，添加Loop List item2脚本
添加Image组件（用于选中的变色）

然后添加子节点， text , id ,name ,age ,grade,

做好了预制体之后，在画布下面添加scrollview

再给scrollview添加 Loop List view2
然后展开给这个脚本挂载一个预制体，这里为MyItem,在接下来的代码会从缓存池里面取，也应该保持一致。

依次创建源代码
