Google Maps - Multiple Markers via URL only

阅读更多关于 Google Maps - Multiple Markers via URL only

If I want to open a browser to Google Maps to center and show a single marker, I do it with a URL like this: https://www.google.com/maps/place//@33.91729,-106.85761,10z/data=!4m2!3m1!1s0x0:0x0 But, I have 5-10 lat/long pairs that I want to show on that same map. How can I show multiple lat/long markers all specified only in a URL? There is an up-to-date article (updated: May 18 2017) about easily linking to locations and directions using the New Google Maps. You could use the directions service and form a url as such : https://www.google.com/maps/dir/33.93729,-106.85761/33.91629,-106.866761/33

问题 I'm trying to create a slider with 3 slides, each containing a mini map with marker pointing to certain location. I managed to create one slide, but every attempt to create more than one on this page results in failure.

Google Maps API v3 in PhoneGap: markers not drawing properly after move

阅读更多关于 Google Maps API v3 in PhoneGap: markers not drawing properly after move

I've been working on a Google Maps API 3 application on Android using PhoneGap. It should track the users location and mark the location with a marker and a circle around it. I had been developing this on Android 2.3 and it was working fine. I then upgraded to a phone with Android 4.x and it was still working well, I thought. Last week I began noticing it doing some strange things when I move the markers. It would seem to create a duplicate marker instead of just moving it. Same with the circle. Sometimes if I change zoom then the duplicates seem to go away. But also, it occasionally draws

阅读更多关于 Animating Multiple Markers

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.

How to implement GMUClusterRenderer in Swift

阅读更多关于 How to implement GMUClusterRenderer in Swift

I am using Google Maps API for iOS and want to use marker clustering utility. I figured out how to show clustered markers, but I would like to customize markers.

How to constantly detect nearby marker locations from current location in Google Maps android?

阅读更多关于 How to constantly detect nearby marker locations from current location in Google Maps android?

I am trying to display a TextView at the top left corner of Google Maps that inform users if they are x distances from particular marker point locations, i.e. "You are close to location A", but only display the TextView if within range. If they move out of range, the TextView will disappear. I understand that the Google Places API shows you all the nearby locations, but I only want to show nearby locations of the markers I have on the map if users are x distances close to them. How can I achieve this? Would I still need to use Google Places API? my class .java: private GoogleMap mMap; private

How to know which Marker was clicked on Google Maps v2 for Android?

阅读更多关于 How to know which Marker was clicked on Google Maps v2 for Android?

I am making an application with a Google Maps on it, for Android. I have plenty of Markers on my screen and I am preparing customizable balloon for each marker when they are clicked. This means, I have information which is different according to the marker which was clicked. I set up the contents of the View of the marker with setInfoWindowAdapter and then I override the method getInfoContents. The problem is: This method is the general implementation of the contents of the Info Window, but each marker shall show its own information. So, as far as I understand, I have to somehow detect on
