我可以使用方向api和此方法获取两个位置之间的距离
我的代码用于获取距离
@Override
public void onDirectionSuccess(Direction direction, String rawBody) {
if (getActivity() != null) {
if (direction.isOK()) {
ArrayList<LatLng> directionPositionList =
direction.getRouteList().get(0).getLegList().get(0).getDirectionPoint();
myMap.addPolyline(DirectionConverter.createPolyline(getActivity(),
directionPositionList, 5, Color.RED));
myMap.addMarker(new MarkerOptions().position(new
LatLng(origin.latitude, origin.longitude)).title("Pickup
Location").snippet(pickup_address).
icon(BitmapDescriptorFactory.defaultMarker
(BitmapDescriptorFactory.HUE_RED)));
myMap.addMarker(new MarkerOptions().position(new
LatLng(destination.latitude, destination.longitude))
.title("Drop Location").snippet(drop_address).icon
(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_GREEN)));
myMap.animateCamera(CameraUpdateFactory.newLatLngZoom(origin,
10));
calculateDistance(Double.valueOf(direction.getRouteList()
.get(0).getLegList().get(0).getDistance().getValue()) / 1000);
如何在Android的Google地图中使用Directions API获取旅行时间?
答案 0 :(得分:1)
我推荐Google提供的Distance Matrix Api。使用此方法,您可以设置最准确的旅行时间的运输方式。
try{
val context = GeoApiContext.Builder()
.apiKey(Constants.GOOGLE_API_KEY)
.build()
val req = DistanceMatrixApi.newRequest(context)
val origin = LatLng(fromlocation.getLatitude(), fromlocation.getLongitude())
val destination = LatLng(tolocation.getLatitude(), tolocation.getLongitude())
val trix = req.origins(origin)
.destinations(destination)
.mode(TravelMode.DRIVING)
.await()
eta = trix.rows[0].elements[0].duration.humanReadable
}catch (ex:Exception){
Log.e("ETA", ex.message)
}

您可以使用Directions api查找起点和终点之间的距离
public String getDistance(final double lat1, final double lon1, final double lat2, final double lon2) {
final String[] parsedDistance = new String[1];
final String[] response = new String[1];
Thread thread = new Thread(new Runnable() {
@Override
public void run() {
try {
URL url = new URL("https://maps.googleapis.com/maps/api/directions/json?origin=" + lat1 + "," + lon1 + "&destination=" + lat2 + "," + lon2 + "&sensor=false&units=metric&mode=driving");
Log.v("urldirection", url.toString());
final HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
InputStream in = new BufferedInputStream(conn.getInputStream());
response[0] = org.apache.commons.io.IOUtils.toString(in, "UTF-8");
JSONObject jsonObject = new JSONObject(response[0]);
JSONArray array = jsonObject.getJSONArray("routes");
JSONObject routes = array.getJSONObject(0);
JSONArray legs = routes.getJSONArray("legs");
JSONObject steps = legs.getJSONObject(1);
JSONObject distance = steps.getJSONObject("duration");
parsedDistance[0] = distance.getString("text");
} catch (JSONException | IOException e) {
Log.v(TAG, e.toString());
}
}
});
thread.start();
try {
thread.join();
} catch (InterruptedException e) {
Log.v("DistanceGoogleAPi", "Interrupted!" + e);
Thread.currentThread().interrupt();
}
return parsedDistance[0];
}
调用此方法将返回距离。根据您的要求更改网址中的查询参数。
