Get number of markers shown in Maps Android

I am showing a list of n markers in a map, then I make zoom to my location and I would like to know if its possible to count just how many markers are displayed in my area.

Thanks.

You can call below method for each marker to see if they are inside the Maps visible area.

map.getBounds().contains(marker.getPosition())

If the getBounds method is not available try this:

VisibleRegion region = map.getProjection().getVisibleRegion();
LatLngBounds mapBound = region.latLngBounds;
int count 0;
for(Marker marker : makers) { // markers is the List of marker you have
  if(mapBound.contains(marker.getPosition()){
    count = count + 1;
  }
}

You can keep a List of marker within your Activity or Fragment and then do a loop on it to see if its in the visible area List.size() to get the number of marker.

private List<Marker> mMarkerArray = new ArrayList<Marker>();


 ///to get number of marker 
 int marker_count = = 0; 
 for(int i =0;i<=mMarkerArray.size();i++){
     if(mMap.latLngBounds.contains(new LatLng(mMarkerArray.get(i).getLocation().getLongitude(), mMarkerArray.get(i).getLocation().getLatitude())){
  marker_count++;
  }
}

just make sure you add the marker in the list after you add it to your map object
