注册 LocationListener的和方法<一href="http://developer.android.com/reference/android/location/LocationListener.html#onLocationChanged%28android.location.Location%29"相对=nofollow> onLocationChanged 绘制起点，并且已经点之间的路径。

Register LocationListener and in method onLocationChanged draw a path between start point and the point that has come.

    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
    }
    ...
}
