Markers change position with zoom in/out

问题

I'm using the Google Maps API v2 for Android, and I want to place a couple of markers on the map. I have the code as following

       @Override
       public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)

       {
        View rootView = inflater.inflate(R.layout.fragment_map, container, false);

        MapFragment fm = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
        map = fm.getMap();
        rootView.findViewById(R.id.map_hybrid).setSelected(true);


        map.setMapType(GoogleMap.MAP_TYPE_HYBRID);
        map.getUiSettings().setCompassEnabled(true);

        CameraPosition cameraPosition = new CameraPosition.Builder()
                                                .target(new LatLng(39.15326,-9.362926))
                                                .zoom(15)
                                                .build();
        MapFragment.newInstance(new GoogleMapOptions()
                        .camera(cameraPosition));

        map.addMarker(new MarkerOptions().position(new LatLng(39.15326,-9.362926))
                .icon(BitmapDescriptorFactory.fromResource(R.drawable.btn_map_home))); 
        while(i < mapInfo.size())
        {
            BitmapDescriptor mapIcon;

            ... changes the resource of the mapIcon accordingly...

            map.addMarker(new MarkerOptions()
                            .draggable(false)
                            .title(((ArrayList<String>) mapInfo.get(i)).get(3))
                            .position(new LatLng(((ArrayList<Double>) mapInfo.get(i)).get(0), ((ArrayList<Double>) mapInfo.get(i)).get(1)))
                            .icon(mapIcon));
            i = i + 1;
        }

And whenever I zoom in and zoom out, the icons move. I want them to be fixed

EDIT: Images explaining the issue.

回答1:

The most likely problem its the image your using as a marker. You must be really carefull that your custom marker points to the same point that the defaults markers or it will not point to the same point once you zoom out enough.

if you use something like this:

The most likely result will be a lot of distortion(and it get worse the more you zoom out!)

Hope this helps you!
