问题 How can i set a listener on an transparent ImageView that is above the map, to only react to pinching (zooming) events on it, while everything else like moving the map gets handled by the Google map? My goal is to create centered zooming on the map which can be done like so: mGoogleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(mGoogleMap.getCameraPosition().target, amountOfZoomNeeded)); but i need to catch that pinch event first, and only that event since onTouch blocks using the map

问题 I have a FragmentActivity with a GoogleMap inside. It correctly receives the user location in onLocationChanged, where I try to use the user location to center the map: @Override public void onLocationChanged(Location loc) { if (centerMap && mMap != null) { LatLng location = new LatLng(loc.getLatitude(), loc.getLongitude()); CameraPosition pos = new CameraPosition.Builder().target(location).zoom(12).build(); CameraUpdate cu = CameraUpdateFactory.newCameraPosition(pos); mMap.animateCamera(cu);

问题 I want to show the current location of the user only on road(not beside of the road) while moving. I have used the LocationManager to get the current location.

I searched lot for this but didn't get any idea. Example: How I am getting the current locations on map. m A---n-------B here, A is start

问题 Previously I used zoom level in google maps by hardcoding. But now it comes from response. So how to convert the meters by passing into zoom level?

LatLng retailerPosition = new LatLng(Double.parseDouble(retailerLatitude), Double.parseDouble(retalerLongitude)); mMap.addMarker(new MarkerOptions().position(retailerPosition).title("").icon
