Google heeft zijn kaart API gewijzigd voor Android en introduceerde API V2. De vorige codes voor tekenpad werken niet met API V2.
Ik heb erin geslaagd een pad te tekenen met API V2. Ik had veel gezocht voor de oplossing, maar vond geen antwoord. Dus ik deel het antwoord.
Antwoord 1, Autoriteit 100%
Allereerst krijgen wij bron- en bestemmingspunten waarmee we route moeten tekenen. Dan zullen we dit attribuut doorgeven aan de onderstaande functie.
public String makeURL (double sourcelat, double sourcelog, double destlat, double destlog ){
StringBuilder urlString = new StringBuilder();
urlString.append("http://maps.googleapis.com/maps/api/directions/json");
urlString.append("?origin=");// from
urlString.append(Double.toString(sourcelat));
urlString.append(",");
urlString.append(Double.toString( sourcelog));
urlString.append("&destination=");// to
urlString.append(Double.toString( destlat));
urlString.append(",");
urlString.append(Double.toString( destlog));
urlString.append("&sensor=false&mode=driving&alternatives=true");
urlString.append("&key=YOUR_API_KEY");
return urlString.toString();
}
Deze functie maakt de URL die we zullen verzenden om richting API-reactie te krijgen. Dan zullen we die reactie parseren. De parser-klasse is
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
// constructor
public JSONParser() {
}
public String getJSONFromUrl(String url) {
// Making HTTP request
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
json = sb.toString();
is.close();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
return json;
}
}
Deze parser retourneert ons string. We zullen het zo noemen.
JSONParser jParser = new JSONParser();
String json = jParser.getJSONFromUrl(url);
Nu sturen we deze reeks naar onze trekpad-functie. De DrawPath-functie is
public void drawPath(String result) {
try {
//Tranform the string into a json object
final JSONObject json = new JSONObject(result);
JSONArray routeArray = json.getJSONArray("routes");
JSONObject routes = routeArray.getJSONObject(0);
JSONObject overviewPolylines = routes.getJSONObject("overview_polyline");
String encodedString = overviewPolylines.getString("points");
List<LatLng> list = decodePoly(encodedString);
Polyline line = mMap.addPolyline(new PolylineOptions()
.addAll(list)
.width(12)
.color(Color.parseColor("#05b1fb"))//Google maps blue color
.geodesic(true)
);
/*
for(int z = 0; z<list.size()-1;z++){
LatLng src= list.get(z);
LatLng dest= list.get(z+1);
Polyline line = mMap.addPolyline(new PolylineOptions()
.add(new LatLng(src.latitude, src.longitude), new LatLng(dest.latitude, dest.longitude))
.width(2)
.color(Color.BLUE).geodesic(true));
}
*/
}
catch (JSONException e) {
}
}
Bovenstaande code tekent het pad op mMap. De code van decodePoly is
private List<LatLng> decodePoly(String encoded) {
List<LatLng> poly = new ArrayList<LatLng>();
int index = 0, len = encoded.length();
int lat = 0, lng = 0;
while (index < len) {
int b, shift = 0, result = 0;
do {
b = encoded.charAt(index++) - 63;
result |= (b & 0x1f) << shift;
shift += 5;
} while (b >= 0x20);
int dlat = ((result & 1) != 0 ? ~(result >> 1) : (result >> 1));
lat += dlat;
shift = 0;
result = 0;
do {
b = encoded.charAt(index++) - 63;
result |= (b & 0x1f) << shift;
shift += 5;
} while (b >= 0x20);
int dlng = ((result & 1) != 0 ? ~(result >> 1) : (result >> 1));
lng += dlng;
LatLng p = new LatLng( (((double) lat / 1E5)),
(((double) lng / 1E5) ));
poly.add(p);
}
return poly;
}
Omdat de richtingaanroep enige tijd kan duren, doen we dit allemaal in de asynchrone taak.
Mijn asynchrone taak was
private class connectAsyncTask extends AsyncTask<Void, Void, String>{
private ProgressDialog progressDialog;
String url;
connectAsyncTask(String urlPass){
url = urlPass;
}
@Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
progressDialog = new ProgressDialog(MainActivity.this);
progressDialog.setMessage("Fetching route, Please wait...");
progressDialog.setIndeterminate(true);
progressDialog.show();
}
@Override
protected String doInBackground(Void... params) {
JSONParser jParser = new JSONParser();
String json = jParser.getJSONFromUrl(url);
return json;
}
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
progressDialog.hide();
if(result!=null){
drawPath(result);
}
}
}
Ik hoop dat het zal helpen.
Antwoord 2, autoriteit 2%
Weet niet of ik dit als antwoord moet zetten of niet…
Ik heb de oplossing van @Zeeshan0026 gebruikt om het pad te tekenen… en het probleem was dat als ik een keer een pad teken, en dan probeer ik opnieuw een pad te tekenen, beide paden worden weergegeven en dit gaat door… toen markeringen werden verwijderd… terwijl, idealiter, oude paden er niet zouden moeten zijn als een nieuw pad is getekend / markeringen zijn verwijderd..
terwijl ik een andere vraag had over SO, had ik de volgende oplossing
Ik voeg de volgende functie toe in de klasse van Zeeshan
public void clearRoute(){
for(Polyline line1 : polylines)
{
line1.remove();
}
polylines.clear();
}
in mijn kaartactiviteit heb ik, voordat ik het pad teken, deze functie aangeroepen.. voorbeeldgebruik volgens mijn app is
private Route rt;
rt.clearRoute();
if (src == null) {
Toast.makeText(getApplicationContext(), "Please select your Source", Toast.LENGTH_LONG).show();
}else if (Destination == null) {
Toast.makeText(getApplicationContext(), "Please select your Destination", Toast.LENGTH_LONG).show();
}else if (src.equals(Destination)) {
Toast.makeText(getApplicationContext(), "Source and Destinatin can not be the same..", Toast.LENGTH_LONG).show();
}else{
rt.drawRoute(mMap, MapsMainActivity.this, src,
Destination, false, "en");
}
u kunt rt.clearRoute();gebruiken volgens uw vereisten..
In de hoop dat het een paar minuten van iemand anders zal besparen en een beginner zal helpen bij het oplossen van dit probleem..
Volledige klascode
zie op github
Bewerken:
hier is een deel van de code van mainactivity..
case R.id.mkrbtn_set_dest:
Destination = selmarker.getPosition();
destmarker = selmarker;
desShape = createRouteCircle(Destination, false);
if (src == null) {
Toast.makeText(getApplicationContext(),
"Please select your Source first...",
Toast.LENGTH_LONG).show();
} else if (src.equals(Destination)) {
Toast.makeText(getApplicationContext(),
"Source and Destinatin can not be the same..",
Toast.LENGTH_LONG).show();
} else {
if (isNetworkAvailable()) {
rt.drawRoute(mMap, MapsMainActivity.this, src,
Destination, false, "en");
src = null;
Destination = null;
} else {
Toast.makeText(
getApplicationContext(),
"Internet Connection seems to be OFFLINE...!",
Toast.LENGTH_LONG).show();
}
}
break;
Bewerk 2
volgens opmerkingen
gebruik:
//variables as data members
GoogleMap mMap;
private Route rt;
static LatLng src;
static LatLng Destination;
//MapsMainActivity is my activity
//false for interim stops for traffic, google
// en language for html description returned
rt.drawRoute(mMap, MapsMainActivity.this, src,
Destination, false, "en");
Antwoord 3
in onderstaande code is midpointsList een ArrayList van waypoints
private String getMapsApiDirectionsUrl(GoogleMap googleMap, LatLng startLatLng, LatLng endLatLng, ArrayList<LatLng> midpointsList) {
String origin = "origin=" + startLatLng.latitude + "," + startLatLng.longitude;
String midpoints = "";
for (int mid = 0; mid < midpointsList.size(); mid++) {
midpoints += "|" + midpointsList.get(mid).latitude + "," + midpointsList.get(mid).longitude;
}
String waypoints = "waypoints=optimize:true" + midpoints + "|";
String destination = "destination=" + endLatLng.latitude + "," + endLatLng.longitude;
String key = "key=AIzaSyCV1sOa_7vASRBs6S3S6t1KofFvDhjohvI";
String sensor = "sensor=false";
String params = origin + "&" + waypoints + "&" + destination + "&" + sensor + "&" + key;
String output = "json";
String url = "https://maps.googleapis.com/maps/api/directions/" + output + "?" + params;
Log.e("url", url);
parseDirectionApidata(url, googleMap);
return url;
}
Kopieer en plak deze url vervolgens in uw browser om te controleren. En de onderstaande code is om de url te ontleden
private void parseDirectionApidata(String url, final GoogleMap googleMap) {
final JSONObject jsonObject = new JSONObject();
try {
AppUtill.getJsonWithHTTPPost(ViewMapActivity.this, 1, new ServiceCallBack() {
@Override
public void serviceCallBack(int id, JSONObject jsonResult) throws JSONException {
if (jsonResult != null) {
Log.e("jsonRes", jsonResult.toString());
String status = jsonResult.optString("status");
if (status.equalsIgnoreCase("ok")) {
drawPath(jsonResult, googleMap);
}
} else {
Toast.makeText(ViewMapActivity.this, "Unable to parse Directions Data", Toast.LENGTH_LONG).show();
}
}
}, url, jsonObject);
} catch (Exception e) {
e.printStackTrace();
}
}
En geef het resultaat dan door aan de drawPath-methode
public void drawPath(JSONObject jObject, GoogleMap googleMap) {
List<List<HashMap<String, String>>> routes = new ArrayList<List<HashMap<String, String>>>();
JSONArray jRoutes = null;
JSONArray jLegs = null;
JSONArray jSteps = null;
List<LatLng> list = null;
try {
Toast.makeText(ViewMapActivity.this, "Drawing Path...", Toast.LENGTH_SHORT).show();
jRoutes = jObject.getJSONArray("routes");
/** Traversing all routes */
for (int i = 0; i < jRoutes.length(); i++) {
jLegs = ((JSONObject) jRoutes.get(i)).getJSONArray("legs");
List path = new ArrayList<HashMap<String, String>>();
/** Traversing all legs */
for (int j = 0; j < jLegs.length(); j++) {
jSteps = ((JSONObject) jLegs.get(j)).getJSONArray("steps");

for (int k = 0; k < jSteps.length(); k++) {

}
Log.e("list", list.toString());
routes.add(path);
Log.e("routes", routes.toString());
if (list != null) {

.addAll(list)
.width(12)
.color(Color.parseColor("#FF0000"))//Google maps blue color #05b1fb
.geodesic(true)
);
}
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}
private List<LatLng> decodePoly(String encoded) {
List<LatLng> poly = new ArrayList<LatLng>();
int index = 0, len = encoded.length();
int lat = 0, lng = 0;
while (index < len) {
int b, shift = 0, result = 0;
do {
b = encoded.charAt(index++) - 63;
result |= (b & 0x1f) << shift;
shift += 5;
} while (b >= 0x20);
int dlat = ((result & 1) != 0 ? ~(result >> 1) : (result >> 1));
lat += dlat;
shift = 0;
result = 0;
do {
b = encoded.charAt(index++) - 63;
result |= (b & 0x1f) << shift;
shift += 5;
} while (b >= 0x20);
int dlng = ((result & 1) != 0 ? ~(result >> 1) : (result >> 1));
lng += dlng;
LatLng p = new LatLng((((double) lat / 1E5)),
(((double) lng / 1E5)));
poly.add(p);
}
return poly;
}
