crash

[MelvinCen]

childFragmentManager.getFragments();获得的list是null，crash

[happyHou]

FragmentManager childFragmentManager = getChildFragmentManager(); List<Fragment> fragments = childFragmentManager.getFragments(); if (!fragments.isEmpty()) { for (Fragment child : fragments) { if (child instanceof LazyLoadBaseFragment && child.isAdded() && !child.isHidden() && child.getUserVisibleHint()) { ((LazyLoadBaseFragment) child).dispatchUserVisibleHint(visible); } } }
我看源代码中有处理。
