我想在谷歌地图绘制路径.我能够在起点和终点之间绘制一条路径,但我想在移动时绘制路径.当我在谷歌地图上移动时,请帮我绘制路径.

解决方法:

注册LocationListener并在方法onLocationChanged中绘制起点和已到达点之间的路径.

    private voID addLocationListener(LocationListener locationListener) {    LocationProvIDer locationProvIDer = getLocationManager().getProvIDer(LocationManager.GPS_PROVIDER);    getLocationManager().requestLocationUpdates(locationProvIDer.getname(), LOCATION_UPDATE_INTERVAL,            LOCATION_UPDATE_MIN_disTANCE, locationListener);}private LocationManager getLocationManager() {    return (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);}private voID startGpsListening(Location start) {   this.startLocation = start;   addLocationListener(new MyLocationListener());}private Location startLocation = new Location("");private class MyLocationListener extends LocationListener {    public voID onLocationChanged(Location location) {        Log.d(LOG_TAG, "New location has come: " + location);        // draw path between startLocarion and this location    }    ...}
