android - Android Google Map API V2 中对应的地理点是什么？

Question

之前，我在 Android Map API v1 中创建了一个扩展 GeoPoint 的类:

class CyclePoint extends GeoPoint {
    public float accuracy;
    public double altitude;
    public float speed;
    public double time;

    public CyclePoint(int lat, int lgt, double currentTime) {
        super(lat, lgt);
        this.time = currentTime;
    }

    public CyclePoint(int lat, int lgt, double currentTime, float accuracy) {
        super(lat, lgt);
        this.time = currentTime;
        this.accuracy = accuracy;
    }

    public CyclePoint(int lat, int lgt, double currentTime, float accuracy, double altitude, float speed) {
    super(lat, lgt);
    this.time = currentTime;
    this.accuracy = accuracy;
    this.altitude = altitude;
    this.speed = speed;
    }
}

现在我正在切换到 V2，我应该扩展什么？应该是 LatLng 吗？但是当我切换到 LatLng 时，它说:类型 CyclePoint 不能子类化最终类 LatLng。谁能帮我这个？非常感谢!

LatLng 对象! http://developer.android.com/reference/com/google/android/gms/maps/model/LatLng.html

这个对象非常有用! 你只需要创建一个实例

ex:
    LatLng home = new LatLng(-34.3232,-8.31331); // instanciate a new Latlng
    home.getLatitude();  // get latitude
    home.getLongitude(); // get longitude

ps:纬度和经度必须是double类型。
