marker

问题 For personal needs, for the Xamarin.Forms.Map control, I need to create a CustomPin extension. UWP part (PCL project) I create a MapIcon like it: nativeMap.MapElements.Add(new MapIcon() { Title = pin.Name, Image = RandomAccessStreamReference.CreateFromUri(new Uri("ms-appx:///Assets/Pin/customicon.png")), Location = new Geopoint(new BasicGeoposition() { Latitude = pin.Position.Latitude, Longitude = pin.Position.Longitude }), NormalizedAnchorPoint = new Windows.Foundation.Point(0.5, 1.0) });

问题 Is it possible to remove the google maps navigation button at bottom right when we click on a marker? I tried this Marker( consumeTapEvents: true, onTap: () { print("marker clicked"); }, infoWindow: InfoWindow( title: "title", snippet: "snippet", onTap: () { markerTap(); }), ) It worked but I ran into a new issue that it doesn't open info window on marker on click. Any suggestion? 回答1: With google_maps_flutter version 0.5.20 they added support to enable/disable this. In your GoogleMap widget

问题 I made a leaflet map with different layers which look like this: L.easyButton('<span class ="buttons">Example </span>', function (btn, map) { if (map.hasLayer(example1)) { map.removeLayer(example1); }; if (map.hasLayer(example2)) { map.removeLayer(example2); }; if (map.hasLayer(example3)) { map.removeLayer(drittpa2017zweit); } map.addLayer(example4); }, 'FirstExample').addTo(map); and so on... I declared a legend, which I only want to use when one layer is on, right now it appears all the

问题 I want to change the marker in the MyLocationOverlay. What I've tried so far is subclassing OSMDroid's MyLocationOverlay and overriding the default marker, using code provided in this answer. However, it didn't work properly (I got the error: method drawMyLocation must override or implement a supertype method but commenting @Override solved it). However, the marker image stays the same (the question asked about Google Maps API, whereas I'm using OSMDroid) - how can I solve it? 回答1: You have a

问题 I'm subscribing to a data stream that gets pushed coordinates, I want to place a marker on the map every time the listener gets a new point. What do I need to do to put the drawMarker code on the correct thread or in the correct scope? @Override public void onMapReady(GoogleMap googleMap) { mMap = googleMap; enableMyLocation(); subscribe(); } public void drawLatestPoint(LatLng p) { System.out.println(p); mMap.addMarker(new MarkerOptions().position(p).title("Marker in Sydney")); } private void

问题 Hey i have a question that seems very tricky. I want to add images for every Infowindow in my map. But the clue is that the images shouldn't parse directly from the XML, because if there are 300 markers and for every marker an image, that would by a very big data which have to load on mapstart. Is it possible to load the image only if the marker has cliked ? Heres my code: <script type="text/javascript"> var side_bar_html = ""; var sidebarMarkers = []; var infoWindow = new google.maps

问题 I created some markers on leaflet map but the only problem is that i dont know how to add a text below each marker and im not talking about popups. What I mean is that the text below the marker has to permanent. For e.g. a text below a marker on India that says "India". I have an example of what Im working on right now: var southWest = L.latLng(-89.98155760646617, -180), northEast = L.latLng(89.99346179538875, 180); var bounds = L.latLngBounds(southWest, northEast); var mymap = L.map('map', {
