问题 I'm trying to achieve the following thing: Have different types of markers on my map for example, schools, libraries, bus stops and I want to be able to show/hide each group of markers. I have been searching google for a while but nothing came up :/ Any ideas how this can be achieved ? 回答1: There are various ways to tackle this, but let me show you one approach. First, let's start with an array of locations (borrowed from the Google Maps API Tutorials): var beaches = [ ['Bondi Beach', -33

问题 I have created an app that implements a MapsView. And when i click the marker, it will show me the info window where the data is retrieved from the database by using picasso. It works fine, but the problem is that the image in the info window not shows me the image that i needed, it still shows me the placeholder image. But when i click the map and click again to the marker, it will shows me the image that i needed. But if i'm not clicking on the map (still clicking the marker), it still

问题 I'm developing an Android application and using GoogleMaps API v2. This application works so far but I want search in the map with a path: Screenshot : my codes: Position_mark = new LatLng(35.7008, 51.437); map.moveCamera(CameraUpdateFactory.newLatLngZoom(Position_mark, 15)); map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null); map.setOnMapClickListener(this); map.setOnMapLongClickListener(this); map.setOnMarkerDragListener(this); ... @Override public boolean onCreateOptionsMenu

问题 I have several markers on a map with polylines drawn. I would like to move each marker along the path of the polyline to simulate simultaneous movement of each marker. I am having problems doing this I am getting only the last marker to move and the rest doesn't. Being new to the use of this programming technology I think something is wrong with my code especially the way I attempt to animate each marker. I need some guidance on this. Here's my work thus far: Jsbin DEMO var startLoc = new

问题 I am using the formula found in this question to find the closest marker on the map to the current position. I would like to modify this formula so that it finds the closet n number of locations(closest 5 locations, closest 10 locations, etc.) and I am not sure how to accomplish this. Here is the modified formula I am using: function rad(x) {return x*Math.PI/180;} function find_closest_marker(center, map) { var lat = center.lat(); var lng = center.lng(); var R = 6371; // radius of earth in km

问题 I am struggling since 2 days with something I was thinking easy, on a map, I have to display a marker for each user with the user FB profile picture inside. I am wondering how I can have a result similar to this one? What I tried was really hackish. I put the FB picture as the marker icon I put a CSS class on the label of the marker I find the sibling to add this border and this arrow to decorate the user picture but it doesn't work when there is more than one marker on the map. .marker

问题 I'd like to know if it possible to change the marker orientation according the path drawn on the map. Here is a example: As you can see the marker is a car (with front bumper and tail lights). I'd like to orientate the car in the direction the path is going (in this exemple orientate the car around 45 degrees to the right). I'm using DirectionsService to draw the path and I have a random number of point. Sometime only one, sometime 10 points. I'm adding the markers before drawing the paths.

问题 I am really stuck on something. Every map marker's infowindow is displaying the same info. It seems to be the content at the end of an array that i use to store content nodes every time. I am pretty sure it is because the infowindow is not being attached to the proper marker var markers = []; var contentArray = []; var titleArray = []; var latlngArray = []; var map; //var infowindow; var concert; function defaultMap() { //Latitude: 38 //Longitude: -97 //window.alert("inside function"); var
