推荐答案

不幸的是，我发现没有办法这样做... 对于那些想要替代解决方案的人. 我尝试使用Viewpager而不是数字选择器使它垂直，我尝试链接并应用了Onpagechangelistner. 简单地完成...

Unfortunately I find out there is no way to do it so... For them who want alternate solution.... I applied Viewpager instead of number picker to make it vertical i tried link and applied Onpagechangelistner. Simply done...
