删除默认用户的位置图标 [英] Remove default user's location icon

问题描述

我正在使用适用于Android的Google Maps v2开发一个应用程序，我设法将自定义图标放置在用户的位置，但是我无法删除默认图标，因此它像图像中一样覆盖了我的自定义图标:

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:

(这是现在那么大的东西:p)

(It is that big just for now :p )

我的代码如下:

@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())));

        }
    });
}

所以: 1)是否可以删除用户当前位置的默认蓝点?

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

2)当我在现实世界"中移动时，是否会更新用户位置(由于连接性原因我无法对其进行测试)，还是我必须编写/重写一种方法来更新用户位置?

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?

预先感谢
