Hi

pls use below code that will help you
ArrayList markersArray = new ArrayList();
for(int i = 0 ; i < markersArray.size() ; i++) {
    createMarker(markersArray.get(i).getLatitude(), markersArray.get(i).getLongitude(), markersArray.get(i).getTitle(), markersArray.get(i).getSnippet(), markersArray.get(i).getIconResID());
}
protected Marker createMarker(double latitude, double longitude, String title, String snippet, int iconResID) {
    return googleMap.addMarker(new MarkerOptions()
            .position(new LatLng(latitude, longitude))
            .anchor(0.5f, 0.5f)
            .title(title)
            .snippet(snippet)
            .icon(BitmapDescriptorFactory.fromResource(iconResID)));
