ConsecutiveViewpager #onMeasure()报错 ，Fragment already added

[PeanutZhang]

遇到一个偶发问题，在友盟后台发现的错误比较多，没有复现， 布局是: smartrefresh+.ConsecutiveScrollerLayout+ consecViewPager -> .ConsecutiveScrollerLayout+ recyclerview+consecViewpager 大佬有空可以看看什么原因吗 Thread Name: 'main' Back traces

这种问题一般是没有处理好Fragment的添加、删除，或者要添加的Fragment发生异常等。你可以网上搜一下这种错误的信息，搜关键字ViewPager+Fragment already added
