如何在android中显示两个位置之间的路由？

我正在使用这个URL

http://maps.google.com/maps?saddr=%f,%f&daddr=%f,%f

显示两点之间的方向页面。 我想知道我可以向这个URL添加什么来获得两点之间的路由

目前，它是显示方向页第一，当我按下路线标签，使它显示路线页，但我想它应该直接转到路线页

我正在使用这个代码

String new_url = "http://maps.google.com/maps?saddr=" + ServerData.LATTITUDE + "," +  ServerData.LONGITUDE + "&daddr=" + latitude + "," + longitude ;

Intent intent_map = new Intent(Intent.ACTION_VIEW, Uri.parse(new_url));
startActivity(intent_map);

请帮助

尝试以下代码。下面的代码将返回纬度和经度位置列表。由此，您必须使用画布为最近的点绘制直线。下面的代码还有一个可以使用的位置标记字符串列表

private ArrayList<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;
        ArrayList<String> pathConent = new ArrayList<String>();
        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.add(path.item(0).getNodeValue());
            }
        }
        placeMarks=new ArrayList<String>();
        NodeList place=doc.getElementsByTagName("Placemark");
        for(int i=0;i<place.getLength();i++){
            Node root=place.item(i);
            NodeList config=root.getChildNodes();
                Node placenode=config.item(0);
                NodeList name=placenode.getChildNodes();
                placeMarks.add(name.item(0).getNodeValue());
                Log.i("Node Value: ", ""+name.item(0).getNodeValue());

        }
        placeMarks.remove((placeMarks.size()-1));
        Log.i("LineString: ", pathConent.get(0));
        ArrayList<String> tmpcoords=new ArrayList<String>();
        for(int i=0;i<pathConent.size();i++){
            tmpcoords.addAll(Arrays.asList(pathConent.get(i).split(" ")));
        }
        //String[] tempContent = pathConent.split(" ");
        return tmpcoords;
    }

Android支持访问内部应用程序及其称为Android内部地图活动的最佳解决方案，以显示两个地理点之间的路线。请参考下面的代码

String uri = "http://maps.google.com/maps?saddr=" + currentLatitude+","+currentLongitude+"&daddr="+fixedLatitude+","+fixedLongitude;
Intent intent = new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(uri));
intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
startActivity(intent);

---

它称为内置地图活动，并在当前和固定纬度和经度之间绘制路线路径。

它调用内置地图活动，并在当前和固定纬度和经度之间绘制路径。

您可以通过在Android中打开默认的Android地图活动来完成相同的操作

您可以查看以下示例代码：

例如网址：`

https://maps.google.com/maps?saddr=28.61000000,77.23000000&daddr=28.98000000,77.02000000


   String uri = "http://maps.google.com/maps?saddr=" + currentLatitude+","+currentLongitude+"&daddr="+destLatitude+","+destLongitude;
    Intent intent = new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(uri));
    intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
    startActivity(intent);
