A sample using marker was recently added. The original source is from osmbonuspack's tutorial

The sample is located here

The basic code is this

GeoPoint startPoint = new GeoPoint(38.8977, -77.0365); //white house Marker startMarker = new Marker(mMapView); startMarker.setPosition(startPoint); startMarker.setAnchor(Marker.ANCHOR_CENTER, Marker.ANCHOR_BOTTOM); startMarker.setIcon(getResources().getDrawable(R.drawable.icon)); startMarker.setTitle("White House"); startMarker.setSnippet("The White House is the official residence and principal workplace of the President of the United States."); startMarker.setSubDescription("1600 Pennsylvania Ave NW, Washington, DC 20500"); mMapView.getOverlays().add(startMarker); mMapView.invalidate();

The osmdroid wiki contains a guide called How to use the osmdroid library. It contains a section about placing icons on the map with a click listener.

Basically you have to create a ItemizedOverlayWithFocus consisting of OverlayItems. Each OverlayItem comes with a title, a description and of course coordinates. The ItemizedOverlayWithFocus has to be added to your MapView.

There is the example from the wiki page:

//your items
ArrayList<OverlayItem> items = new ArrayList<OverlayItem>();
items.add(new OverlayItem("Title", "Description", new GeoPoint(0.0d,0.0d))); // Lat/Lon decimal degrees

//the overlay
ItemizedOverlayWithFocus<OverlayItem> mOverlay = new ItemizedOverlayWithFocus<OverlayItem>(items,
    new ItemizedIconOverlay.OnItemGestureListener<OverlayItem>() {
    @Override
    public boolean onItemSingleTapUp(final int index, final OverlayItem item) {
    //do something
        return true;
    }
    @Override
    public boolean onItemLongPress(final int index, final OverlayItem item) {
        return false;
    }
});
mOverlay.setFocusItemsOnTap(true);

mMapView.getOverlays().add(mOverlay);
