Я внедрил OnMarkerClickListener и изменил код от Is there an API for Google Maps navigation in Android?, чтобы увидеть, будет ли он работать, но когда вы нажимаете на маркер, карта просто масштабируется в нем? Что мне не хватает? - EDIT: Я редактировал код ниже и теперь при нажатии на маркер в приложение падает с К сожалению приложение Остановлено ЗапускMarker Нажимаем намерение не работать
Благодаря
@Override //This is going after my setUpMap(); method
public boolean onMarkerClick(Marker marker) {
double lati = marker.getPosition().latitude;
double longi = marker.getPosition().longitude;
Location currentLocation = mMap.getMyLocation();
double latitudeCurr = currentLocation.getLatitude();
double longitudeCurr = currentLocation.getLongitude();
final Intent intent = new Intent(Intent.ACTION_VIEW,
Uri.parse("+http://maps.google.com/maps?" + "saddr=" + latitudeCurr + "," + longitudeCurr + "&daddr=" + lati + "," + longi));
intent.setClassName("com.google.android.apps.maps","com.google.android.maps.MapsActivity");
startActivity(intent);
return true;
}
