以前,我创建了一个在Android Map API v1中扩展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 …
