android-maps-v2

问题 I am using Google Maps V2 for Android together with maps utils extension library for marker clustering. Some parts of app does not need to get clustered markers. Is there any way to forbid clusterManager to cluster markers and after certain conditions let it cluster items again? 回答1: I found myself another solution. I figured out that on DefaultClusterRenderer method shouldRenderAsCluster is responsible for whether the marker will be rendered as cluster or not. So I created a CustomRenderer

问题 I want to slow the update rates as soon as I got a location precise enough for my needs: @Override public void slowUpdateRate() { /* * Set the update interval */ Dbg.v(TAG,"****************************"); Dbg.e(TAG, "-- SLOW update rate"); Dbg.v(TAG,"****************************"); stopUpdates(); mLocationRequest.setInterval(1500000); mLocationRequest.setFastestInterval(150000); mLocationClient.requestLocationUpdates(mLocationRequest, this); The method is called but I still got updates every

问题 Google Navigation shows the traffic layer only for a given route. With GoogleMap.setTrafficEnabled(true) I'll get the traffic information for the whole map. I know how to draw polylines for a route from Google Directions, but how can I turn on the traffic layer only for that route? 回答1: Not possible as of API v2 version 3.1.36. You may want to post a feature request on gmaps-api-issues. 回答2: The difference between these two values (duration and a duration in traffic) indicates how delayed

问题 I am drawing polyline on my map,I need to show some data to user now. How I can draw text or InfoWindow on each polyline ? I add polyline like : ArrayList<LatLng> points = null; PolylineOptions lineOptions = null; MarkerOptions markerOptions = new MarkerOptions(); // Traversing through all the routes for(int i=0;i<result.size();i++){ points = new ArrayList<LatLng>(); lineOptions = new PolylineOptions(); String color = colors[i % colors.length]; // Fetching i-th route List<HashMap<String,

问题 Hi I'm trying to implement Google Maps display in my app using Google Map Android API v2, and I am trying to follow the solution in here. Codes seem to be okay except when I tried this part: public class MapFragment extends SherlockMapFragment { private GoogleMap mMap; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View root = super.onCreateView(inflater, container, savedInstanceState); mMap = getMap(); return root; } } The getMap

问题 I have been trying relentlessly to use this library. Everytime I add it, I lose all android.support.v4 and com.google.android.gms.maps cababilities. There is very little documentation for this library. Is there any tutorial that I have overlooked in my extensive Google searching? Here's my gradle file: dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile 'com.android.support:appcompat-v7:21.0.3' compile 'com.google.android.gms:play-services:6.5.87' compile 'com

问题 Well , I have couple of topic related with this issue but still did not got the logic besides nobody provides a clear solution. Anyway, I will try to ask it again clearly and provide a screenshot (from a sample app) hope it would do the magic.

In there address change dynamically when the markers position change on the maps. BUT we
