包路径：android.support.v4.app.Fragment
类名称：Fragment
方法名：isDetached

Fragment.isDetached介绍

[英]Return true if the fragment has been explicitly detached from the UI. That is, FragmentTransaction#detach(Fragment) has been used on it.
[中]如果片段已从UI显式分离，则返回true。也就是说，FragmentTransaction#detach（Fragment）已在其上使用。
