json

mainactivity.java

w3wnetworkfactory.w3wgetinstance().w3wgetapicall().getposition(w3w_api_key, new words("gliders.inquest.hardly"), new callback<positionresponse>() {             @override             public void success(positionresponse positionresponse, response response) {                 position_w3w.settext(arrays.tostring(positionresponse.getposition()).replaceall("\\[|\\]", ""));                 //log.d("w3w location: ", arrays.tostring(positionresponse.getposition()));                 string mlatlng = arrays.tostring(positionresponse.getposition()).replaceall("\\[|\\]", "");                 //convert string double                 double value = double.parsedouble(mlatlng);                 //set marker map                 mgooglemap.addmarker(new markeroptions().position(value)                         .title("geolocation system")                         .snippet("your last current location available!")                         .icon(bitmapdescriptorfactory.fromresource(r.drawable.icon_location)));             }              @override             public void failure(retrofiterror error) {                 error.tostring();             }         }); 

positionresponse.java

public class positionresponse {     private double[] position;      public double[] getposition() {         return position;     } } 

to answer question google map, need separate out lat , lon, , create latlng object. think should this:

    @override                 public void success(positionresponse positionresponse, response response) {                     position_w3w.settext(arrays.tostring(positionresponse.getposition()).replaceall("\\[|\\]", ""));                     //log.d("w3w location: ", arrays.tostring(positionresponse.getposition()));                     string mlatlng = arrays.tostring(positionresponse.getposition()).replaceall("\\[|\\]", "");                      string[] arrlatlng = mlatlng.split(","); //separate out lat , lon                     latlng latlon = new latlng(double.parsedouble(arrlatlng[0]), double.parsedouble(arrlatlng[1])); //create latlng object                      //convert string double                     //double value = double.parsedouble(mlatlng); wouldn't work, need both values individually                     //set marker map, use latlng object latlon                     mgooglemap.addmarker(new markeroptions().position(latlon)                             .title("geolocation system")                             .snippet("your last current location available!")                             .icon(bitmapdescriptorfactory.fromresource(r.drawable.icon_location)));                       cameraposition cameraposition = new cameraposition.builder()                         .target(latlon).zoom(12).build();                        mgooglemap.animatecamera(cameraupdatefactory                         .newcameraposition(cameraposition));                 }
