Google Maps API 2 MapView Not Updating

由 强颜欢笑 提交于 2019-12-07 09:25:18
问题 I'm displaying a Google Maps API v2 MapView in an Android app, but it's curiously not updating properly in a consistent fashion. I'm using the GPS to update the map position (tried both LocationManager and LocationClient) and although the map moves to the position, about fifty percent of the time either the street name layer fails to update or there's a fuzzy/blurry section that fails to update--until I do a manual drag (scroll) of the map. Then the entire map updates instantly. I've stripped

Google Maps Android Clustering OnCameraChangeListener() deprecated

由 好久不见. 提交于 2019-12-07 03:18:23
问题 Using the tutorial here, I successfully implemented clustering in my Android app. Since OnCameraChangeListener() is now deprecated in com.google.android.gms:play-services:9.4.0 is there a new way to implement the part below? private ClusterManager<MyItem> mClusterManager; googleMap.setOnCameraChangeListener(mClusterManager); EDIT: I tried directly replacing setOnCameraChangeListener by setOnCameraMoveListener like googleMap.setOnCameraMoveListener(mClusterManager); This does not work since

由 爱⌒轻易说出口 提交于 2019-12-07 02:48:21
问题 I'm converting an old application from v1 to v2, and I'm having a problem with the color of my Marker icons. I have a basic, white icon, and It needs to be colorized. In v1, I did it this way : Drawable d = DrawableUtils.resizeImageToDrawable( MapViewFragment.mapviewActivity, Configuration.Display.getDrawableFix(i), Configuration.MapView.getWaypointIconWidth(), Configuration.MapView.getWaypointIconHeight()); d.setColorFilter(color, Mode.MULTIPLY); overlay = new MyFplnFixListItimizedOverlay(d)

由 浪尽此生 提交于 2019-12-07 02:15:11

Here is my code: public void onMapReady(GoogleMap map) { double latitude = 33.750587; double longitude = -84.4199173; LatLng latLng = new LatLng(latitude,longitude); map.moveCamera
