--------------------

**出现的原因**

> This seems to be a bug in the newly added support for nested fragments. Basically, the child FragmentManager ends up with a broken internal state when it is detached from the activity. A short-term workaround that fixed it for me is to add the following to onDetach() of every Fragment which you call getChildFragmentManager() on:

**解决方法**

*  stackoverflow上面给的解决办法是重写onDetach方法，测试行不通

@Override
    public void onDetach() {
        super.onDetach();
    
        try {
            Field childFragmentManager = Fragment.class.getDeclaredField("mChildFragmentManager");
            childFragmentManager.setAccessible(true);
            childFragmentManager.set(this, null);
    
        } catch (NoSuchFieldException e) {
            throw new RuntimeException(e);
        } catch (IllegalAccessException e) {
            throw new RuntimeException(e);
        }
    }

--------------------

*  在使用该Viewpager的Fragment中，重写方法onDestroyView()，测试有效

@Override
    public void onDestroyView() {
    super.onDestroyView();
    try {
           Field childFragmentManager = Fragment.class.getDeclaredField("mChildFragmentManager");
           childFragmentManager.setAccessible(true);
           childFragmentManager.set(this, null);
    
    
        } catch (NoSuchFieldException e) {
           throw new RuntimeException(e);
        } catch (IllegalAccessException e) {
           throw new RuntimeException(e);
        }
    }

> 为什么在onDetach行不通呢，因为按照Activity跟Fragment的生命周期图来看，onDetach阶段Fragment已经与Activity脱离关系——即Fragment持有的Activity对象已被置null，而onDestroyView阶段Fragment中仍然保留与Activity之间的关系,此时Fragment持有的Activity对象仍然有效。
