کار با مارکر در مپ

این کد رو امتحان کن :

 mMap.setOnMapClickListener(newGoogleMap.OnMapClickListener(){
@Override
public void onMapClick(LatLng point){//save current location
            latLng = point;
List<Address> addresses =newArrayList<>();
try{
                addresses = geocoder.getFromLocation(point.latitude, point.longitude,1);
}catch(IOException e){
                e.printStackTrace();
}

            android.location.Address address = addresses.get(0);
if(address !=null)
{StringBuilder sb =newStringBuilder();
for(int i =0; i < address.getMaxAddressLineIndex(); i++){
                    sb.append(address.getAddressLine(i)+"\n");
}Toast.makeText(MapsActivity.this, sb.toString(),Toast.LENGTH_LONG).show();
}//remove previously placed Marker
if(marker !=null){
                marker.remove();
}//place marker where user just clicked
            marker = mMap.addMarker(newMarkerOptions().position(point).title("Marker").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_MAGENTA)));}});

این هم امتحان کن

 private GoogleMap.OnMyLocationChangeListener myLocationChangeListener =newGoogleMap.OnMyLocationChangeListener(){
@Override
public
void onMyLocationChange(Location location){
LatLng loc =newLatLng(location.getLatitude(), location.getLongitude());
        mMarker = mMap.addMarker(newMarkerOptions().position(loc));
if(mMap !=null){
            mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(loc,16.0f));}}};

mMap.setOnMyLocationChangeListener(myLocationChangeListener);
