如何在 dismiss() DialogFragment 后刷新 Fragment 上的 RecycleView？

Question

Could you tell me the way to refresh data on RecycleView on Fragment. On DialogFragment, there are some TextInputEditText, and users could change the data. After users closed DialogFragment with dismiss(), RecycleView isn't changed.

Tried to use Intetnt back to RecycleView, but I think it is not correct way. My environment is JAVA, Android Studio.
