google-maps-android-api-2

问题 Google Maps API v2 Whilst I was waiting for another app to be finalised I was creating another out of interest that would only enable 1 marker to be added to a map at a time (I love maps I do). I currently have this code which will clear the map if a marker already exists and then add another one. But what I wanted was for it to show a message telling to user to clear the map before it will allow another marker to be added. @Override public void onMapClick(LatLng position){ if (position !=

问题 I'm trying to add Google Maps fragments into a RecyclerView in Android. I was reading about it and I saw that I need to create the fragments dynamically instead of doing it by XML to avoid the duplicate ID errors. Here is my adapter code : public class MapViewHolder extends RecyclerView.ViewHolder { protected FrameLayout mapContainer; public MapViewHolder(View v){ super(v); view = v; mapContainer = (FrameLayout) v.findViewById(R.id.mapContainer); } } private void bindMapRow(final

问题 I have an activity with Navigation Drawer and HomeFragment . HomeFragment contains two nested fragments (child fragments): SupportMapFragment and ActionFragment . I declare the GoogleMap object sMap as static in HomeFragment , so it can be accessed and modified by the nested fragment ActionFragment . Everything works fine in the first run. The map can be manipulated from within the ActionFragment . But when the HomeFragment is removed and reloaded at a later point of time, the map could only

问题 I have a InfoWindowAdapter class in my Android app that refers to an xml layout containing three TextViews. I add a new marker using the code below within an addMarker() method: mapView.addMarker(new MarkerOptions() .position(latLon) .title(titleText) .snippet(snippetText) .icon(BitmapDescriptorFactory.fromResource(R.drawable.pin_green))); mapView.setInfoWindowAdapter(new InfoWindow(getLayoutInflater())); mapView.setOnInfoWindowClickListener(this); I then set the text of my two infowindow

问题 I am trying since long time to show the StreetView of particular location in Android but unfortunately unable to succeed. What i require is that if i provide a position(LAT,LONG) to the map it should show the streetview of that particular position. Following is the working code that shows Map, 3D map, hybrid map, sattlatite view etc etc.. BUT not showing the STREETVIEW... mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap(); mMap.addMarker(new

问题 I want to confirm one thing in Google maps that is why Google maps always showing South Africa as default location ... Can't we change Australia as Default one . If GPRS enabled I can trace the current location if not i want to show Sidney in Australia . Is it possible ??? 回答1: Google Maps will show the user's current location if you ask for it. You can also manually set the "default" location by moving the map to give a particular location. CameraUpdate point = CameraUpdateFactory.newLatLng

问题 I am trying to take advantage of an InfoWindowAdapter to provide custom content for the InfoView. I'm pulling down a JSONArray from my web service and adding the Markers but I'm not seeing how to pass the detail to the call back via a Marker. @Override public View getInfoWindow(Marker marker) In the Javascript API I was able to just set arbitrary marker info. I want to be able to pass info that can be used as conditionals for the custom content, example a marker.status string. So something

问题 Is there a function that allows specifying default padding values for different edges of the MapFragment , i.e. similar to CameraUpdateFactory.newLatLngBounds(LatLngBounds bounds, int padding) which already exists, but instead something like CameraUpdateFactory.newLatLngBounds(LatLngBounds bounds, int paddingTop, int paddingLeft, int paddingBottom, int paddingRight) ? Why I need this : In my MapFragment I have a half transparent layer on top. Therefore I need a wider padding at the top than
