i trying have simpler implementation of google map in android app. able launch google map unable show multiple markers there. if keep latitude , longitude values , name of places hardcoded things work, dynamically variables , string values unable show them. have gone through link suggested many on here. want simpler implementation of it.
below code have used in main activity:
public class map_activity_with_fragment extends appcompatactivity implements onmapreadycallback { private googlemap googlemap; string origin, destination, start_date, num_adult, num_infant, origin_map, destination_map; context context; list<address> addr_origin, addr_dest; double latitude_origin, longitude_origin, latitude_destination, longitude_destination; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); intent intent = getintent(); bundle extras = intent.getextras(); origin = extras.getstring(mainactivity.origin); destination = extras.getstring(mainactivity.destination); start_date = extras.getstring(mainactivity.start_date); num_adult = extras.getstring(mainactivity.adult); num_infant = extras.getstring(mainactivity.infant); origin_map = extras.getstring(mainactivity.origin_map); destination_map = extras.getstring(mainactivity.destination_map); context = map_activity_with_fragment.this; settitle("location map"); setcontentview(r.layout.activity_map__with__fragment); try { initializemap(); } catch (exception e) { e.printstacktrace(); } } @override public boolean oncreateoptionsmenu(menu menu) { // inflate menu; adds items action bar if present. getmenuinflater().inflate(r.menu.activity_map__with__fragment, menu); return true; } @override public boolean onoptionsitemselected(menuitem item) { // handle action bar item clicks here. action bar // automatically handle clicks on home/up button, long // specify parent activity in androidmanifest.xml. int id = item.getitemid(); //noinspection simplifiableifstatement if (id == r.id.action_settings) { return true; } return super.onoptionsitemselected(item); } @override public void onmapready(googlemap googlemap) { addmarkers(googlemap); } @override protected void onresume() { super.onresume(); initializemap(); } private void initializemap() { if (googlemap == null) { mapfragment mapfragment = (mapfragment) getfragmentmanager().findfragmentbyid(r.id.map); mapfragment.getmapasync(this); } } private void addmarkers(googlemap googlemap) { try { geocoder geocoder = new geocoder(context); addr_origin = geocoder.getfromlocationname(origin_map, 1); addr_dest = geocoder.getfromlocationname(destination_map, 1); if (addr_origin.size() > 0) { latitude_origin = addr_origin.get(0).getlatitude(); longitude_origin = addr_origin.get(0).getlongitude(); } if (addr_dest.size() > 0) { latitude_destination = addr_dest.get(0).getlatitude(); longitude_destination = addr_dest.get(0).getlongitude(); } marker m1 = googlemap.addmarker(new markeroptions().position(new latlng(latitude_origin, longitude_origin)).title(origin_map)); marker m2 = googlemap.addmarker(new markeroptions().position(new latlng(latitude_destination, longitude_destination)).title(destination_map)); } catch (exception e) { e.printstacktrace(); } } } please me out! in advance!
ok, going update own question.
i testing these code changes on device of api level 16, , hence markers , polylines not getting rendered correctly. tested same code on device of api level 19, , worked fine. did not modify part of code this. things working now. :)
