问题 Using the Android maps api I'm creating polygons as I collect location data from every third point. The polygons track my position fairly well. Problem is: Frequently the GPS returns points that are not remotely close especially when working around obstacles. How can I filter my location data for outliers? 回答1: Yes GPS has a hard time with especially around obstacles. Powerlines, buildings, etc. Simply filter them out. @Override public void onLocationChanged(Location location) { if (!location

问题 I am using Google Map API to get lines on the map in my application. I am loading the nodes of the lines from a database using following code: // Add polyline "walks voda" List<WalkLine> dbwalknodes = dbclass.queryWalksFromDatabase(this); // list of latlng for (int i = 0; i < dbwalknodes.size() - 1 ; i++) { WalkLine source = dbwalknodes.get(i); WalkLine destination = dbwalknodes.get(i+1); Polyline line = mMap.addPolyline(new PolylineOptions() .add(new LatLng(source.getLat(), source.getLon()),

问题 I need to embed a SupportMapFragment in a Dialog . This is the best I could think of: public class SupportMapFragmentDialog extends DialogFragment { private final SupportMapFragment fragment; public SupportMapFragmentDialog() { fragment = new SupportMapFragment(); setTargetFragment(fragment, 1); } @Override public View onCreateView(final LayoutInflater inflater, final ViewGroup container, final Bundle savedInstanceState) { return fragment.onCreateView(inflater, container, savedInstanceState);

问题 I am developing an app using App Inventor. It includes the need for a user to press a button - to save a location when they are at the location. But every time this is not practical. So I want to implement a method in my App Inventor app which will: -Open Google Maps -Let the user select any point on the map with no additional info. -After choosing, return to the app and return latitude, longitude values for the location that is selected. This is really important for me, help will be

问题 I am trying to customise the state_pressed behaviour of an InfoWindow in Google Maps. Normally when this InfoWindow is pressed, it turns yellow. That's also the case with custom InfoWindows. But I want to change this to another colour, like red or orange or blue. So I created a very simple custom InfoWindow like this: class MyInfoWindowAdapter implements InfoWindowAdapter { private final View myContentsView; MyInfoWindowAdapter() { myContentsView = getLayoutInflater().inflate(R.layout.popup,

问题 I am using Google Map V2. I need to show the ListView (custom ListView with Image) in custom InfoWindow . I tried it and got success only in View , the problem is I can't get the listItemClick event. googleMap.setInfoWindowAdapter(new InfoWindowAdapter() { @Override public View getInfoWindow(Marker arg0) { // TODO Auto-generated method stub return null; } @Override public View getInfoContents(Marker arg0) { View v = getLayoutInflater().inflate(R.layout.infowindow, null); try{ String[] names =

问题 I want to move camera to position to fit LatLngBounds with regard to marker height. So far I'm able for fit the anchors of markers with this code: LatLngBounds.Builder builder = new LatLngBounds.Builder(); for (Marker marker : markerList) { builder.include(marker.getPosition()); } LatLngBounds bounds = builder.build(); int padding = getActivity().getResources().getDimensionPixelSize(R.dimen.home_map_padding); // offset from edges of the map in pixels cameraUpdate = CameraUpdateFactory
