Android 删除默认用户';s位置图标

Android 删除默认用户';s位置图标,android,google-maps-android-api-2,Android,Google Maps Android Api 2,我正在使用Google Maps v2 for Android开发一个应用程序,我设法在用户的位置上放置了一个自定义图标,但我无法删除默认图标,因此它覆盖了我的自定义图标,如图所示: (就目前而言,它有那么大:p) 我的代码如下: @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.ac

我正在使用Google Maps v2 for Android开发一个应用程序,我设法在用户的位置上放置了一个自定义图标,但我无法删除默认图标,因此它覆盖了我的自定义图标,如图所示:

(就目前而言,它有那么大: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())));

        }
    });
}
因此: 1) 有没有办法删除用户当前位置的默认蓝点

2) 当我在“真实世界”中移动时,是否会更新用户位置(出于连接原因,我无法对其进行测试),或者我是否必须编写/重写一个方法来更新用户位置


提前感谢

您将不得不停止使用
GoogleMap.setMyLocationEnabled
并编写更多代码,包括拥有自己的代码和添加
圆圈
,以确保准确性

你必须自己去做。 -设置为false
gmaps.getUiSettings().setMyLocationButtonEnabled(false)

  • 创建自己的位置按钮
  • 如果您得到当前位置,请在该位置上设置一个带有图标的标记
  • 如果单击“位置”按钮,请移动相机并将其置于地图中心
这将删除蓝点

谢谢joao2fast4u(lol)和ṁᾶƔƏň ツ. 我按照你的建议做了,我成功地做到了。由于我没有看到这个问题的任何具体答案,我在这里发布了我的解决方案:

map.setMyLocationEnabled(true);删除行
