通过使用接口将BottomSheetDialogFragment和其父Fragment解耦，以确保数据更改不会影响父Fragment中的数据。

首先，在BottomSheetDialogFragment中创建一个接口：

public interface BottomSheetListener {
    void onDataChanged(String data);
}

然后在BottomSheetDialogFragment中将接口与数据绑定：

public class MyBottomSheet extends BottomSheetDialogFragment {

    private BottomSheetListener mListener;
    private EditText mEditTextData;

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);

        try {
            mListener = (BottomSheetListener) context;
        } catch (ClassCastException e) {
            throw new ClassCastException(context.toString()
                    + " must implement BottomSheetListener");
        }
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.bottom_sheet, container,
                false);

        mEditTextData = view.findViewById(R.id.edit_text_data);
        Button buttonOk = view.findViewById(R.id.button_ok);

        buttonOk.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String data = mEditTextData.getText().toString();
                mListener.onDataChanged(data);
                dismiss();
            }
        });

        return view;
    }
}

最后，在父Fragment中实现接口以获取BottomSheetDialogFragment中的更改数据：

public class MyFragment extends Fragment implements BottomSheetListener {

    private TextView mTextViewData;
    private String mText = "";

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment, container,
                false);

        mTextViewData = view.findViewById(R.id.text_view_data);

        Button buttonShowDialog = view.findViewById(R.id.button_show_dialog);
        buttonShowDialog.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                MyBottomSheet bottomSheet = new MyBottomSheet();
                bottomSheet.show(getFragmentManager(), "BottomSheet");
            }
        });

        return view;
    }

    @Override
    public void onDataChanged(String data) {
        mText =
