marker

问题 I know this has been discussed before, but I actually can't find a solution. I am adding a custom icon for my marker: markerUserLocation = mMap.addMarker(new MarkerOptions().position(new LatLng(point.latitude, point.longitude)) .anchor(0.5f, 1.0f) .icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_marker_my_location))); The problem is when zooming in/out the marker gets positioned in a bad place. I have tried to play with the anchor values, but no success. Isn't the default anchor mid

问题 In our application, a lot of markers are drawn in different locations and in certain cases at a certain zoom level, markers overlap each other.

Is there anyway to tell the map to refresh the data in the marker bubble? 回答1: Call

问题 I'm using the Maki set of icons, but they are very limited and would like to be able to use Font Awesome icons. Is this possible?

问题 I am having a really hard time waiting for the ChartPlotter in D3 to show itself, when using markers. Of course I am trying to plot a Gazillion records (well, 700,000 records). When using just a line, all is well (20 seconds or so). When using markers, we're talking 5 minutes. That's not acceptable. Any ideas? Here's what I have done, with explanations under it. public static string MakeSimplePlot(double[][] xData, double[][] yData, string[] legend, string xAxisTitle, string yAxisTitle, bool[

问题 I want the string in my snippet to be aligned to the center. Also, line breakers (\n) in the snippet are converted to spaces, is there a way to insert line breakers?

问题 I am using Google Maps API V2 to get the location of the current user and am recording his route by using the onLocationChanged listener. While the user records their route I save all the LatLngs detected at each location change in an arraylist.
