Adding markers to map from ArrayList

Question

I have the coordinates of my markers in a LatLng arraylist. I add all the markers to a marker arraylist.

for(int i=0; i<markers_location.length; i++){
    coords_markers.add(new LatLng(lat_markers.get(i), lon_markers.get(i)));}

List<Marker> markers = new ArrayList<>();
for(int i=0; i<markers_location.length; i++){
    Marker marker = mMap.addMarker(new MarkerOptions().position(coords_markers.get(i)));
    markers.add(marker);
}

How can I then add these markers to the map? I tried this:

mMap.addMarker(markers.get(0));

But it doesn't work.

you have already added the marker when you called mMap.addMarker in your for loop. — Linxy

You are right, I already added it at the for loop. I was just confused because I needed the marker arraylist to change all the markericons on zoom change. — Tamas Koos

Try this:

for(int i=0; i<markers_location.length; i++){
coords_markers.add(new LatLng(
lat_markers.get(i).getLatitude, 
lon_markers.get(i).getLongitude));}
