而Activity的onPause()会调用它所管理的Fragment的同样的方法,但是当我使用replace时,已经remove掉了原来的Fragment,所以当调用原理的Fragment的onPause()方法就回不存在,就会出现上述xxx is not currently in the FragmentManager的异常推出
界面A(有viewpager)--(跳到)编辑界面B--保存返回界面A,这时候推出界面A,必然发生IllegalStateException: <Fragment> is not currently in the FragmentManager。

titleList);要改为 FragmentAdapter adapter = new FragmentAdapter(getChildFragmentManager(),fragments,titleList);这个问题主要是fragment里面嵌套fragment造成各，再嵌套fragment里的类里面将获取FragmentManager的函数由getActivity().getSupportFragmentManager()换成getChildFragmentManager()函数就可以了。
二. getFragmentManager() 改为 getChildFragmentManager(), 简单点说就是即前者只为activity中表层fragment提供服务, 而后者为fragment中的fragment提供服务。 然而都没有解决我那个情况, 后来慢慢debug, 最终发现将findViewById()前的getActivity()改为getView(), 问题解决了(也需要满足上面两种情况)!
