android ViewPager2+TabLayout、滑动效果相关问题！

ViewPager2+TabLayout、会遇到底部tab点击 过度滚动问题、 比如tab一共有四页、当从第1页切换到第四页、会有动画滚动效果、如何去除动画效果？请往下看、若没有此问题就不用往下看了；

 控制ViewPager2+TabLayout 滚动效果得核心TabLayoutMediator、具体用法不再阐述、展示其核心代码：

是的答案就在这里、

viewPager.setCurrentItem(tab.getPosition(), smoothScroll);

讨厌的动画就是smoothScroll==true 导致的、这个值可以在初始化TabLayoutMediator时设置、用来取消滚动动画；

如下：

如果有这样的需求、点击tab无动画、滑动有动画（类似微信）？ 请继续往下看；

TabLayoutMediator 是final类  且smoothScroll字段时私有的、我们没法继承重写、但是可以copy源码修改、不会有问题、核心修改如图

已下是修改好的完整代码
