How can I add marker dynamically?

[swanhtet1992]

Are there ways to add markers dynamically depending on the area of the map which is shown?
I found that Android Map Extensions [https://code.google.com/p/android-maps-extensions/] has this functionality.
Can we be also achieve like that with this library?

I don't want to switch library since this library is very convenient. 😸

Thanks,
SH

I'm not sure what you mean - can you just add an OnCameraChangeListener?

The PointQuadTree class might help to do bounding box queries if you have a lot of markers.

@mg6maciej‎ do you know what SH is referring to? Is that something we should/could incorporate into this utils library?

Oh, I think I know what you mean. Yes, I'm working on it - performance is terrible when zoomed very far in, because all markers are still added to the map (eventually).

I think this is the same as issue #29. Going to close this as a dupe. Thank you!

👍 Thank you. 😄

Yes. There is ClusteringSettings.addMarkersDynamically(boolean) in AME, which is a must when working with a lot of markers. A compromise between UX and performance: adding only onscreen markers.

That was one of the very first requests when I started working on AME. Promoting AMU next to the official maps library brought you a lot of attention ;)

googleMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {
            @Override
            public void onMapClick(LatLng latLng) {
                MarkerOptions marker = new MarkerOptions().position(
                        latLng)
                        .title("Hello Maps ");
                marker.icon(BitmapDescriptorFactory
                        .defaultMarker(BitmapDescriptorFactory.HUE_AZURE));
                googleMap.addMarker(marker);
            }
        });
