此方法在对话框碎片被消除时触发。重写对话框片段中的方法。

@Override
public void onDismiss(@NonNull DialogInterface dialog) {
    super.onDismiss(dialog);
    // use interface to callback method in base fragment
}

我不确定，但我试过破解密码，成功了。

@Override
public void dismiss() {
    super.dismiss();
    ((MyActivity)context).myRefreshFunction();// 
}

调用BottomSheetDialogFragment
单击事件打开按钮SheetDialgFragment

class GuestFragment : Fragment(){
        .
        .
        .
        .

        override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
            super.onViewCreated(view, savedInstanceState)
            binding.tvInfo.setOnClickListener {
                val dialogFragment = BottomSheetDogGiveReviewFragment(requireContext(),data.ratingData,data)
                // call back method
                dialogFragment.setOnBottomSheetDismissListener  {
                    resumeFragment()
                }
                dialogFragment.show(parentFragmentManager, "My  Fragment")
            }

        }
