我正在使用这个网址
http://maps.google.com/maps?saddr=%f,%f&daddr=%f,%f
显示两点之间的方向页。
我想知道我可以添加到此URL以获得两点之间的路线。
当前它首先显示方向页,当我按路线选项卡时它显示路线页,但是我要直接直接转到路线页。
我正在使用此代码
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);
请帮忙
最佳答案
尝试下面的代码。以下代码将返回纬度和经度位置列表。由此,您必须使用画布绘制最接近点的线。以下代码还提供了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;
}
