Answer 1

这个是因为你在onCreatView()里面，view已经存在，并且有parent了，需要将parent的子view删除就可以了。http://blog.csdn.net/renpengben/article/details/12615487

Answer 2

这个错误 很明显不会是你切换Framgnet的时候报错的 而是你的Fragment本身就有错

关于异常“The specified child already has a parent. You must call removeView＂的解决以及产生的原因
这个异常的出现往往是因为非法使用了某些方法引起的。http://www.jcodecraeer.com/a/anzhuokaifa/androidkaifa/2014/0923/1708.html
