我有两个片段 - 父片段和子片段。我的父片段由RecyclerView和CardView组成，包含一些用户数据，Child Fragment包含Cardview内容的详细页面，其中包含一些喜欢和评论按钮。当我点击子片段中的like按钮时，在后面按下父片段没有通过详细页面中所做的更改来刷新。 我试过在onResume方法中调用我的API，但它似乎不起作用!!!

也许它不是很好的方法，但你可以尝试像首先在背景上删除那个片段
getActivity().getSupportFragmentManager().popBackStack();
getActivity().getSupportFragmentManager().beginTransaction().remove(this).commit();
然后调用你父级的onresume并加载要加载或刷新的数据。！
((MainActivity) getContext()).onResume();
