获取驾驶方向的android代码

我目前正在做一个android应用程序，需要获取驾驶方向。我有起点和终点纬度和经度，我得到了两点之间的路径，但我不能得到行驶方向。请帮我。。。路径的代码如下所示

            GeoPoint gp1;
        GeoPoint gp2 = startGP;

        for (int i = 1; i < pairs.length; i++) {
            lngLat = pairs[i].split(",");
            gp1 = gp2;
            // watch out! For GeoPoint, first:latitude, second:longitude
            gp2 = new GeoPoint((int) (Double.parseDouble(lngLat[1]) * 1E6),
                    (int) (Double.parseDouble(lngLat[0]) * 1E6));
            myMapView.getOverlays().add(new DirectionPathOverlay(gp1, gp2));
            Log.d("xxx", "pair:" + pairs[i]);
        }

        myMapView.getOverlays().add(new DirectionPathOverlay(gp2, gp2));

        myMapView.getController().animateTo(startGP);
        myMapView.setBuiltInZoomControls(true);
        myMapView.displayZoomControls(true);



}


 private String[] getDirectionData(String srcPlace, String destPlace) {

        String urlString = "http://maps.google.com/maps?f=d&hl=en&saddr="
                + srcPlace + "&daddr=" + destPlace
                + "&ie=UTF8&0&om=0&output=kml";
        Log.d("URL", urlString);
        Document doc = null;
        HttpURLConnection urlConnection = null;
        URL url = null;
        String pathConent = "";
        try {

            url = new URL(urlString.toString());
            urlConnection = (HttpURLConnection) url.openConnection();
            urlConnection.setRequestMethod("GET");
            urlConnection.setDoOutput(true);
            urlConnection.setDoInput(true);
            urlConnection.connect();
            DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
            DocumentBuilder db = dbf.newDocumentBuilder();
            doc = db.parse(urlConnection.getInputStream());

        } catch (Exception e) {
        }

        NodeList nl = doc.getElementsByTagName("LineString");
        for (int s = 0; s < nl.getLength(); s++) {
            Node rootNode = nl.item(s);
            NodeList configItems = rootNode.getChildNodes();
            for (int x = 0; x < configItems.getLength(); x++) {
                Node lineStringNode = configItems.item(x);
                NodeList path = lineStringNode.getChildNodes();
                pathConent = path.item(0).getNodeValue();
            }
        }
        String[] tempContent = pathConent.split(" ");
        return tempContent;
    }

尝试使用此代码显示从当前位置到某个位置的方向

locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
    Criteria criteria = new Criteria();
    provider = locationManager.getBestProvider(criteria, false);
    Location location = locationManager.getLastKnownLocation(provider);

    if (location != null) {
        System.out.println("Provider " + provider + " has been selected.");
        lat = (double) (location.getLatitude());
        lng = (double) (location.getLongitude());

    } else {
        Log.d(TAG, "Cannot get the location");
    }

    final Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://maps.google.com/maps?" + "saddr="+ lat + "," + lng + "&daddr="+hotelLat+","+hotelLng));
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(intent);

检查这些标杆和[[1]：检查这个我不想画路径，我想知道驾驶方向

locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
    Criteria criteria = new Criteria();
    provider = locationManager.getBestProvider(criteria, false);
    Location location = locationManager.getLastKnownLocation(provider);

    if (location != null) {
        System.out.println("Provider " + provider + " has been selected.");
        lat = (double) (location.getLatitude());
        lng = (double) (location.getLongitude());

    } else {
        Log.d(TAG, "Cannot get the location");
    }

    final Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://maps.google.com/maps?" + "saddr="+ lat + "," + lng + "&daddr="+hotelLat+","+hotelLng));
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(intent);
