Android:如何更新另一个片段上的微调数据

public class TargetFragment extends Fragment {
    private TextView dataTextView;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_target, container, false);
        dataTextView = view.findViewById(R.id.dataTextView);
        return view;
    }

    public void updateData(String newData) {
        dataTextView.setText(newData);
    }
}

public class SourceFragment extends Fragment {
    private Button updateButton;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_source, container, false);
        updateButton = view.findViewById(R.id.updateButton);
        updateButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                TargetFragment targetFragment = (TargetFragment) getFragmentManager().findFragmentById(R.id.targetFragment);
                targetFragment.updateData("New data");
            }
        });
        return view;
    }
}
