我想找到两个地点之间的距离。我有经度和纬度，我可以计算欧氏距离。但我想找到道路距离。我的意思是，我想计算从源头到目的地时我正在进行的道路距离。在这种情况下如何计算？
答案 0 :(得分：7)
最简单的方法是使用Google Directions API获取路线，这会为您提供路线上所有点的列表（以及总距离）。
退房：http://code.google.com/apis/maps/documentation/directions/
如果你不确定怎么做，请告诉我，我会为你发布一些代码，这些代码将从谷歌获取指示并提取你需要的数据。
更新 - 根据要求提供的代码
private void GetDistance(GeoPoint src, GeoPoint dest) {
StringBuilder urlString = new StringBuilder();
urlString.append("http://maps.googleapis.com/maps/api/directions/json?");
urlString.append("origin=");//from
urlString.append( Double.toString((double)src.getLatitudeE6() / 1E6));
urlString.append(",");
urlString.append( Double.toString((double)src.getLongitudeE6() / 1E6));
urlString.append("&destination=");//to
urlString.append( Double.toString((double)dest.getLatitudeE6() / 1E6));
urlString.append(",");
urlString.append( Double.toString((double)dest.getLongitudeE6() / 1E6));
urlString.append("&mode=walking&sensor=true");
Log.d("xxx","URL="+urlString.toString());
// get the JSON And parse it to get the directions data.
HttpURLConnection urlConnection= null;
URL url = null;
url = new URL(urlString.toString());
urlConnection=(HttpURLConnection)url.openConnection();
urlConnection.setRequestMethod("GET");
urlConnection.setDoOutput(true);
urlConnection.setDoInput(true);
urlConnection.connect();
InputStream inStream = urlConnection.getInputStream();
BufferedReader bReader = new BufferedReader(new InputStreamReader(inStream));
String temp, response = "";
while((temp = bReader.readLine()) != null){
//Parse data
response += temp;
}
//Close the reader, stream & connection
bReader.close();
inStream.close();
urlConnection.disconnect();
//Sortout JSONresponse
JSONObject object = (JSONObject) new JSONTokener(response).nextValue();
JSONArray array = object.getJSONArray("routes");
//Log.d("JSON","array: "+array.toString());
//Routes is a combination of objects and arrays
JSONObject routes = array.getJSONObject(0);
//Log.d("JSON","routes: "+routes.toString());
String summary = routes.getString("summary");
//Log.d("JSON","summary: "+summary);
JSONArray legs = routes.getJSONArray("legs");
//Log.d("JSON","legs: "+legs.toString());
JSONObject steps = legs.getJSONObject(0);
//Log.d("JSON","steps: "+steps.toString());
JSONObject distance = steps.getJSONObject("distance");
//Log.d("JSON","distance: "+distance.toString());
String sDistance = distance.getString("text");
int iDistance = distance.getInt("value");
}
这将返回两点之间的距离，您可以更改函数以将其作为字符串或整数返回，只返回sDistance或iDistance。
希望这对您有所帮助，如果您需要更多帮助，请告诉我。
答案 1 :(得分：5)
使用google地图距离矩阵API http://code.google.com/apis/maps/documentation/distancematrix/。
答案 2 :(得分：1)
由于您已经在使用Google地图，请查看the driving directions api。
（BTW，谷歌地图API v3？我会假设是）
对于一对lat / lng点，您可以请求行车路线
在API3中，它看起来像这样：
var directionsService = new google.maps.DirectionsService();
var start = from; // A Google LatLng point or an address,
// see their API for further details
var end = to; // A Google LatLng point or an address,
//see their API for further details
var request = {
origin: start,
destination: end,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function (response, status) {
//Check if status Ok
//Distance will be in response.routes[0].legs[0].distance.text
});
验证响应状态是否正常，然后确保存在路由集合。如果是，则有结果，您可以通过以下方式访问“距离”文本元素：
response.routes[0].legs[0].distance.text
希望有所帮助。

我看到有几个人已正确回答，但看看这个答案。使用谷歌地图方向api非常有用的API。 Google Maps Direction Api usage
答案 4 :(得分：0)
肯尼的改进答案对我有用，我根据我修改了一些东西。引入LatLng而不是geopoint。我发布的工作代码是Kenny的答案的修改版本。所有学分都归于肯尼而不是我！
重点：
以字符串格式传递地址。例如：多伦多
复制此功能：
private void GetDistance(String src, String dest) {
String s = src.replaceAll("\\s","+");
String d = dest.replaceAll("\\s","+");
StringBuilder urlString = new StringBuilder();
urlString.append("http://maps.googleapis.com/maps/api/directions/json?");
urlString.append("origin=");
urlString.append((s));
urlString.append("&destination=");
urlString.append((d));
urlString.append("&mode=driving&sensor=true");
Log.d("xxx", "URL=" + urlString.toString());
// get the JSON And parse it to get the directions data.
HttpURLConnection urlConnection = null;
URL url = null;
try {
url = new URL(urlString.toString());
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("GET");
urlConnection.setDoOutput(true);
urlConnection.setDoInput(true);
urlConnection.connect();
InputStream inStream = urlConnection.getInputStream();
BufferedReader bReader = new BufferedReader(new InputStreamReader(inStream));
String temp, response = "";
while ((temp = bReader.readLine()) != null) {
//Parse data
response += temp;
}
//Close the reader, stream & connection
bReader.close();
inStream.close();
urlConnection.disconnect();
//Sortout JSONresponse
JSONObject object = (JSONObject) new JSONTokener(response).nextValue();
JSONArray array = object.getJSONArray("routes");
Log.d("xxx", "array: " + array.toString());
//Routes is a combination of objects and arrays
JSONObject routes = array.getJSONObject(0);
Log.d("xxx", "routes: " + routes.toString());
//String summary = routes.getString("summary");
//Log.d("JSON","summary: "+summary);
JSONArray legs = routes.getJSONArray("legs");
Log.d("xxx", "legs: " + legs.toString());
JSONObject steps = legs.getJSONObject(0);
Log.d("JSON", "steps: " + steps.toString());
JSONObject distance = steps.getJSONObject("distance");
Log.d("xxx", "distance: " + distance.toString());
String sDistance = distance.getString("text");
int iDistance = distance.getInt("value");
Log.d("SEE THE DIST : ", "" + sDistance + iDistance);
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
}
由于此函数执行网络操作，我们必须使用AsyncTask，如下所示：
private class Task extends AsyncTask<Void, Void, Void> {
@Override
protected Void doInBackground(Void... params) {
GetDistance(from, to);
return null;
}
}
