我有一个Vaadin应用程序,我想集成Google热图。我正在使用com.vaadin.tapio.googlemaps依赖项来显示地图,它工作正常。但是,我不确定如何在Google地图顶部添加热图层,并且找不到任何相关资源。我的审判代码Vaadin如何添加Google热图
有关部分看起来是这样的:
VerticalLayout rootLayout = new VerticalLayout();
rootLayout.setSizeFull();
// Google Map
GoogleMap googleMap = new GoogleMap("api_key", null, null);
googleMap.setZoom(10);
googleMap.setSizeFull();
googleMap.setMinZoom(4);
googleMap.setMaxZoom(16);
Panel mapsPanel = new Panel();
mapsPanel.setSizeFull();
mapsPanel.setContent(googleMap);
rootLayout.addComponent(mapsPanel);
double centerLon = 8.5417;
double centerLat = 47.3769;
googleMap.setCenter(new LatLon(centerLat, centerLon));
GoogleMapMarker centerMarker = new GoogleMapMarker("Zurich", new LatLon(centerLat, centerLon),true, null);
googleMap.addMarker(centerMarker);
HeatMapLayer heatMapLayer = HeatMapLayer.newInstance(HeatMapLayerOptions.newInstance());
// Add data to heatmap
...
// How can I add this HeatMapLayer to the existing map?
// Or do I need a different approach?
UI.getCurrent().setContent(rootLayout);
我尝试了叉;然而,他们的热图对我没有任何帮助。我尝试了他们的演示,并将'GoogleMapHeatMapLayer'集成到了我的应用中,但都没有成功。尽管如此,谢谢你的信息。 – Egemen
