google-maps-markers

问题 I would like implement a live tracking in Android using Google maps. I want to show the user's movement as they move from one location to another by changing the position of the marker on the map. 回答1: Because the user location changes, you must account for movement by re-estimating user location every so often. read the full story here: https://developer.android.com/guide/topics/location/strategies.html 回答2: you need to make LocationRequest after a fix interval and listen to location change

For example, I would like to have the icon returned from the JSON of Google Places API: "icon" : "http://maps.gstatic.com/mapfiles/place_api/icons/generic_business-71.png" Here's how I am doing it now without adding the icon: for (Place place : mNearPlaces.results) { LatLng placeLatLng = new LatLng(place.geometry.location.lat, map.addMarker(new MarkerOptions() .position(placeLatLng) .title(place.name)); } I looked at

问题 I'm using the webcomponent google-map-marker in a Polymer element created by me.

问题 I am currently putting together a demo application that needs to show 28,000 markers on a map without using any type of clustering. The problem is, adding the marker to the map for that many takes so long that the browser crashes!

问题 Using Google Maps Android API v2, I can update my marker's position by getting the Marker from a hashMap and then calling: Marker marker = hashMap.get(someId); marker.setTitle("Title"); marker.setSnippet("Snippet"); marker.setPosition(new LatLng(newLatitude, newLongitude)); However, if the marker is selected when this is called, the title and snippet will only update if I click off the marker and reselect it.

问题 I have several markers shown on my map that are either close to each other or even over top of one another. I need to have one specific marker always on top. It doesn't matter if I add the marker to the map first or last, it often ends up being placed behind some markers. For some mysterious reason, Google Maps determines this.
