Question

我正在使用Google Maps v2 for Android开发应用程序，我设法将自定义图标添加到用户的位置，但我无法删除默认图标，因此它会覆盖我的自定义图标，就像在图像：

enter image description here

（现在这很大：p）

我的代码就像：

@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）有没有办法删除用户当前位置的默认蓝点？

2）当我进入真实世界时，用户位置是否会更新＆＃34; （我不能为了连接性而测试它）或者我是否必须编写/覆盖一个方法来更新用户位置？

提前致谢

Answer 1

您必须停止使用GoogleMap.setMyLocationEnabled并再写一些代码，包括拥有自己的LocationClient并添加Circle以确保准确性。

你必须自己做。 - 设置为false gmaps.getUiSettings().setMyLocationButtonEnabled(false);

创建您自己的位置按钮
如果您获得当前位置，请在
如果您点击您的位置按钮，请移动相机并将其居中到地图

这将删除蓝点

Answer 2

map.setMyLocationEnabled（真）;删除行
