I am very new to android google maps i want display distance between two places .for that i write the two autocompletedtextview i get the from and to Locations .by using the

public String host = "https://maps.googleapis.com";
public String searchPath = "/maps/api/place/autocomplete/json";
public String detailsPath = "/maps/api/place/details/json";

I got the places names as string i want calculate the distance between two places using that two string places how can i achieve it Thanks in Advance.

I use the Haversine formula, [see here](http://stackoverflow.com/a/13183753/1134705) for an example. — jnthnjns, Nov 03 '12 at 05:59

i think this code usefull for you :

double distance

Location locationA = new Location(“point A”)

locationA.setLatitude(latA)

locationA.setLongitude(lngA)

Location locationB = new Location(“point B”)

locationB.setLatitude(latB)

LocationB.setLongitude(lngB)

distance = locationA.distanceTo(locationB)

usually better off using the built in method than rolling your own +1 – Luke Nov 03 '12 at 06:05

To find Distance Try this just pass start and end point return you distance

 double distance;
 GeoPoint StartP;
 GeoPoint EndP;

    distance=CalculationByDistance(StartP,EndP);

    public double CalculationByDistance(GeoPoint StartP, GeoPoint EndP) {
            double Radius = 6371;
            double lat1 = StartP.getLatitudeE6() / 1E6;
            double lat2 = EndP.getLatitudeE6() / 1E6;
            double lon1 = StartP.getLongitudeE6() / 1E6;
            double lon2 = EndP.getLongitudeE6() / 1E6;
            double dLat = Math.toRadians(lat2 - lat1);
            double dLon = Math.toRadians(lon2 - lon1);
            double a = Math.sin(dLat / 2) * Math.sin(dLat / 2)
            + Math.cos(Math.toRadians(lat1))
            * Math.cos(Math.toRadians(lat2)) * Math.sin(dLon / 2)
            * Math.sin(dLon / 2);
            double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));
            double temp = Radius * c;
            temp=temp*0.621;
            return temp;
        }

autoCompleteTextView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView> arg0, View view, int pos, long id) { startplace=adapter.getItem(pos); System.out.println("=========START PLACE==========="+startplace); //onPlaceSelected(adapter.getItem(pos)); } }); – user1787493 Nov 03 '12 at 06:10
by this i am getting the start and end places ? – user1787493 Nov 03 '12 at 06:10
how can i find distance based on these two places ? – user1787493 Nov 03 '12 at 06:10
@user1787493 get your geopoint in two diffrent variable and just pass that geopoint to this function. – J.D. Nov 03 '12 at 06:13
how can i get lat and lang positions of the seleted places in the autocompleted textview? – user1787493 Nov 03 '12 at 06:16
@user1787493 i am not getting what you want to do. function that i have post will give you distance between two Geo point. – J.D. Nov 03 '12 at 06:21
how can i get lat and lang postions based on place section? – user1787493 Nov 03 '12 at 06:31
@user1787493 From where you select place? – J.D. Nov 03 '12 at 06:45
from AutocComplete Textview places list? – user1787493 Nov 03 '12 at 06:47
@user1787493 from where you place come? – J.D. Nov 03 '12 at 06:49
public Place(String name, String reference, double lat, double lng) { super(name, reference); this.lat = lat; this.lng = lng; } – user1787493 Nov 03 '12 at 06:52
@user1787493 get lat long in on select of autocomplete view and convert that lat long to geopoint and pass that geopoint to this function. – J.D. Nov 03 '12 at 06:57
