阅读更多关于 dynamic Polyline colors with google maps android app

问题 I'm using Android Google Map utils to enable clustering of my Markers. I'm using 10 Markers When I press on a button, I call: mGoogleMap.moveCamera(CameraUpdateFactory.newLatLngBounds(getMarkerBoundingBox(), MAP_PADDING)); Eight of my markers are close to a given region so they are clustering and I can see a blue ball with the number eight on the center. The other two markers are far away from the other group but are really close to each other. I'm now seeing a cluster with the eight markers
