如何接收从alertDialog片段到实际活动的yes/no值？

public class MainActivity extends AppCompatActivity {
    // ...

    public void onDialogResult(boolean result) {
        if (result) {
            // 用户选择了yes
            // 执行相应的操作
        } else {
            // 用户选择了no
            // 执行相应的操作
        }
    }

    public void showDialog() {
        AlertDialogFragment dialogFragment = new AlertDialogFragment();
        dialogFragment.setOnDialogResultListener(this::onDialogResult);
        dialogFragment.show(getSupportFragmentManager(), "alertDialog");
    }
}

public class AlertDialogFragment extends DialogFragment {
    private OnDialogResultListener mListener;

    public interface OnDialogResultListener {
        void onDialogResult(boolean result);
    }

    public void setOnDialogResultListener(OnDialogResultListener listener) {
        mListener = listener;
    }

    @NonNull
    @Override
    public Dialog onCreateDialog(@Nullable Bundle savedInstanceState) {
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setTitle("提示")
                .setMessage("是否确认执行操作？")
                .setPositiveButton("是", (dialog, which) -> {
                    if (mListener != null) {
                        mListener.onDialogResult(true);
                    }
                })
                .setNegativeButton("否", (dialog, which) -> {
                    if (mListener != null) {
                        mListener.onDialogResult(false);
                    }
                });
        return builder.create();
    }
}
