Problem passing database data to TextView android

I'm not able to display database data for TextView.

BD

public MessageEB buscarConfiguracoes() {

    String[] colunas = new String[]{"data"};

    Cursor cursor = bd.query("dados", colunas, null, null, null, null, null);

    MessageEB messageEB = new MessageEB();

    if (cursor.moveToNext()) {
        messageEB.setData(cursor.getString(0));
    }

    cursor.close();

    return messageEB;
}

Fragment Submit

@Override
    public void onClick(View v) {
        Log.i("LOG", "FragmentEnviar.this.onClick()");

        MessageEB m = new MessageEB();
        m.setClassTester(FragmentExibir.class+"");
        m.setData(editar.getText().toString());

        EventBus.getDefault().post(m);

        dados.setData(editar.getText().toString());
        BD bd = new BD(getActivity());
        bd.atualizar(dados);

        Toast.makeText(getActivity(), "Data alterada com sucesso! " + dados.getData(), Toast.LENGTH_SHORT).show();
    }

Fragment View

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

        EventBus.getDefault().register(FragmentExibir.this);


    txt = (TextView) view.findViewById(R.id.campoData2);


    BD bd = new BD(getActivity());
    txt.setText(bd.buscarConfiguracoes().getData());

    return view;
}

Data is the name of the database table. When I call the database data, it is not displayed.
