Remove default user's location icon

问题:

Im developing an app using Google Maps v2 for Android and I managed to put a custom icon to the user's position but I can't remove the default one, so it overlays my custom icon like in the image:

(It is that big just for now :p )

My code is like:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_map);

    map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

    map.setMyLocationEnabled(true);

    map.setOnMyLocationChangeListener(new OnMyLocationChangeListener() {

        @Override
        public void onMyLocationChange(Location location) {
            if (location == null)
                return;

            mPositionMarker = map.addMarker(new MarkerOptions()
            .flat(true)
            .icon(BitmapDescriptorFactory
                    .fromResource(R.drawable.logop1))
            .anchor(0.5f, 1f)
            .position(new LatLng(location.getLatitude(), location.getLongitude())));

        }
    });
}

So: 1) Is there a way to remove the default blue dot of user's current location?

2) Will the user location be updated when I move in the "real world" (I cant test it for conectivity reasons) or do I have to write/override a method to update users position?

Thanks in advance

回答1:

You will have to stop using GoogleMap.setMyLocationEnabled and write a bit more code, including having your own LocationClient and adding Circle for accuracy.

You have to do that on your own. - set to false gmaps.getUiSettings().setMyLocationButtonEnabled(false);

  • create your own location button
  • if you get your current location, set a marker with your icon on that
  • if you click on your location button, move the camera and center it to the map

That will remove the blue dot



回答2:

map.setMyLocationEnabled(true); remove line

Thanks joao2fast4u (lol) and ṁᾶƔƏň ツ. I followed your recomendations and I managed to make it work. Since I didn't see any answer concrete to this problem I'm posting my solution here:

        } else
