google-maps-api-2

问题 I'm new to development within android using the Google Maps API. I've been able to set up a map and test out the basic functionality, but I'm having trouble implementing the logic shown in the documentation into my own code. I've researched and found through google's documentation you must have the map check if traffic data is available by using: public final boolean isTrafficEnabled() and then calling the method: public final boolean isTrafficEnabled() { return mMap.isTrafficEnabled(); }

问题 May I know how to add numbering label to google map marker using google map api? Just add label, not trying to change the icon. Thank you. 回答1: If you don't want to use custom icons for each marker then I suggest looking into creating a label class with the OverlayView and then binding the position to the marker.

问题 How would you track the location of a user for the entire day, like the timeline in Google maps? I have two ideas For example, if I have 200 LatLng values per day, how do I pass all of these LatLng values to Google map as points?

Is there any Google API to track the user throughout the whole day and make a timeline for it? 回答1: If you have 200 LatLng point you always can just draw them as polyline: ... final

问题 Everything was working ok, then suddenly eclipse started breaking asking for a perspective switch and going to debug mode with the error 'Link of class "Lcom/google/android/gms/location/internal/ParcelableGeoFence;" failed. Googling the problem lead nowhere. Debugger points to PathClassLoader(BaseDexClassLoader).findClass(String) line: 61 Strangely when I remove map.setMyLocationEnabled(true); from my code it no longer crashes but still I can see this in logcat E/dalvikvm(5639): Could not

问题 I have an arraylist which consists of latLong object as shown below: ArrayList < LatLng > latLngList = new ArrayList< LatLng >(); Note: LatLng is an object which has latitude and longitude values in double format i.e., Latitude is in double format and Longitude is in double format The below are the values which are stored in the above latLngList object: Lat Long List:[lat/lng: (34.072516,-118.403609), lat/lng: (34.074227,-118.399248), lat/lng: (34.07304,-118.3995), lat/lng: (34.07304,-118

问题 http://econym.org.uk/gmap/example_eshapes.htm has a Google Maps API v2 example of how to tile hexagons, although the implementation scales painfully: it has a center hexagon, then six hexagons adjacent to it in the appropriate directions, then (in quasi-recursion) three hexagons adjacent to one of the hexagons adjacent to the original hexagon. And it has a nice border with transparent fill. How can I create a similar effect, but preferably with tiling so that I specify (without mounds of

问题 Do anyone have idea how this animation's implementation is possible in google map api v2. Check out this here. I would like to know how this is done. Please let me know if anyone have any sample code regarding this. Thanks in advance. 回答1: I found a solution that worked for me: final LatLng target = NEW_LOCATION; final long duration = 400; final Handler handler = new Handler(); final long start = SystemClock.uptimeMillis(); Projection proj = map.getProjection(); Point startPoint = proj

问题 I calculated the wind direction and now I want to show the wind direction pointing to 144 degrees (on compass). How can I show this arrow on Google Maps? 回答1: In order to show an arrow over a google map you can create a Rich Marker that embed an image using the google-maps-utility-library-v3, Next apply a rotation in degree to the image element with css3 tranformations. In example : // content element of a rich marker var richMarkerContent = document.createElement('div'); // arrow image var
