高度为0dp的MapView不显示

我在活动的片段上有一个mapview，它有一个约束布局。我需要它来适应片段中的其余空间，所以我使用“0dp”高度。

问题是它没有显示，但如果我给它一个固定的高度，如“150dp”，它显示正确。

可能是什么问题？感谢

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

    // Asignacion layout.
    asignaComponentes(view);
    asignaTipoLetra();

    fragmentoPadre = container;

    inicializaCups();

    actualizaTablaUltimosConsumos();

    mapView.onCreate(savedInstanceState);
    mapView.getMapAsync(this);
    actualizaMapa();

    return view;
} 

     @Override
public void onMapReady(GoogleMap gmap) {
    map = gmap;
    setUpMap(null);
}

public void setUpMap(Cups cupsMapa){
    map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
}

@Override
public void onResume() {
    mapView.onResume();
    super.onResume();

}

@Override
public void onDestroy() {
    super.onDestroy();
    mapView.onDestroy();
}

@Override
public void onLowMemory() {
    super.onLowMemory();
    mapView.onLowMemory();
}

这是带有Constraint布局的XML Capture of XML
