I have successfully fetched the Latitude and Longitude from some data stored in the Database. But I am unable to update the marker location on the map. Can please someone help me with the code or as to how to do that.
Try this using CameraUpdate ,
LatLng coordinate = new LatLng(lat, lng); //Store these lat lng values somewhere. These should be constant.
CameraUpdate location = CameraUpdateFactory.newLatLngZoom(coordinate, 15);
mMap.animateCamera(location);
Or can also use this,
LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
MarkerOptions markerOptions = new MarkerOptions();
markerOptions.position(latLng);
markerOptions.title(totalAddress); //Here Total Address is address which you want to show on marker
mMap.clear();
markerOptions.icon(
BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_AZURE));
markerOptions.getPosition();
mCurrLocationMarker = mMap.addMarker(markerOptions);
mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
mMap.animateCamera(CameraUpdateFactory.zoomTo(11));

Currently, my marker setting is this, and the marker title is just "marked" for now:
final MarkerOptions markerOptions = new MarkerOptions();
markerOptions.position(latLng);
markerOptions.title("Marked");
markerOptions.draggable(false);
markerOptions.icon(BitmapDescriptorFactory.fromResource(R.drawable.marker3));
mCurrLocationMarker = mMap.addMarker(markerOptions);
How can I title the markers as the coordinates they are placed on?
You should convert latLng to coordinates and the use markerOptions.title(convertedCoordinates);
I was setting mMap.setMyLocationEnabled(true) and I am successfully getting my current location but...
Not able to zoom to that position.
Not able to get lat and lng from that position
From getting latitude and longitude I am using below code but it gives me null. I am calling below method from onMapReady(Google Map) and passing google map object.
private void goToCurrentLocation(GoogleMap map) {
Log.d("Tag", "inside");
Location loc = map.getMyLocation();
if (loc != null) {
LatLng point = new LatLng(loc.getLatitude(), loc.getLongitude());
Log.d("Tag=", "latlng=" + point);
map.animateCamera(CameraUpdateFactory.newLatLngZoom(point, 15));
}
}
Is there any alternative to getting latitude and longitude as getMyLocation deprecated?
use link provided in the answer to get current location and then zoom over that location using below code:
latLng = new LatLng(location.getLatitude(), location.getLongitude());
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(latLng, 10);
mGoogleMap.animateCamera(cameraUpdate);

I have a Jar with geopoints, I use this bit of code to find the nearest city :
GetNService gn = new GetNService();
NGeoPoint nearest = gn.getN(lat, lon);
GeoPoint city = nearest.getPoint();
I would like to add a marker, but I don't know how to add with Geopoint.
Thanks
You can get the lat and lang values from a GeoPoint like so
GetNService gn = new GetNService();
NGeoPoint nearest = gn.getN(lat, lon);
GeoPoint city = nearest.getPoint();
double lat = city.getLatitude();
double lon = city.getLongitude();
you can add a Marker like so
map.addMarker(new MarkerOptions()
.position(new LatLng(lat, lon))
.title("Marker Title"));
After I find this Location mCurrentLocation = mLocationClient.getLastLocation(); how can I add a marker to that that location?
Making a marker like
MarkerOptions marker = new MarkerOptions().position(new LatLng(latitude, longitude))
requires a position object, is there a way that I can retrieve a position from the Location object? or is this done in some other way?
You can use the getLatitude() and getLongitude() of the Location class which will return double which by then you can pass it in your new LatLong constructor.
sample:
MarkerOptions marker = new MarkerOptions().position(new LatLng(mCurrentLocation.getLatitude(), mCurrentLocation.getLongitude()))
i have a set of lat long coordinates. i want to display all of those markers at a time on google map. I know how to display a single marker. But don't know how to display multiples at once. Anybody please help me.
Thank you.
i have lat long points.
like
id = 123 lat = 12.00 lon = 77.00
id = 124 lat = 12.01 lon = 77.01
etc.
May This Help You
for(int pin=0; pin<pins.size(); pin++)
{
LatLng pinLocation = new LatLng(Float.parseFloat(pins.get(pin).latitude), Float.parseFloat(pins.get(pin).longitude));
Marker storeMarker = map.addMarker(new MarkerOptions()
.position(pinLocation)
.title(pins.get(pin).pinname)
.snippet(pins.get(pin).address)
);
}
Try this:
LatLng one = new LatLng(2.40744, 77.014702);//Latitude and long points
LatLng two = new LatLng(2.407440, 77.014702);
.......
Similarly u can use more lat and long
myMarkerOne = gm.addMarker(new MarkerOptions()
.position(one)//use LatLng obj
.title("C")
.snippet("dsfd")
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_GREEN)));
myMarkerTwo = gm.addMarker(new MarkerOptions()
.position(two)
.title("C")
.snippet("dsfds")
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_GREEN)));

Also check this link:
Create a LatLng object by using following format:
LatLng location = new LatLng(latitude, longitude);
Then call the method with your LatLng object along with your GoogleMap object:
private Marker setCurrentLocation(LatLng location, GoogleMap map) {
BitmapDescriptor bitmapDescriptor = BitmapDescriptorFactory
.fromResource(R.drawable.user_location_pin);
Marker marker = map.addMarker(new MarkerOptions().position(location)
.icon(bitmapDescriptor).title(location.toString()));
return marker;
}
