You can use ItemizedOverlay to add mutiple layout. here has a sample code of ItemizedOverlay
`public class YourItemizedOverlay extends ItemizedOverlay {

private ArrayList<OverlayItem> myOverlays ;

public YourItemizedOverlay(Drawable defaultMarker) {
    super(boundCenterBottom(defaultMarker));
    yourOverlays = new ArrayList<OverlayItem>();
    populate();
}

public void addOverlay(OverlayItem overlay){
    yourOverlays.add(overlay);
    populate();
}

@Override
protected OverlayItem createItem(int i) {
    return yourOverlays.get(i);
}

// Removes overlay item i
public void removeItem(int i){
    yourOverlays.remove(i);
    populate();
}

@Override
public int size() {
    return yourOverlays.size();
}


public void addOverlayItem(OverlayItem overlayItem) {
    yourOverlays.add(overlayItem);
    populate();
}


public void addOverlayItem(int lat, int lon, String title) {
    try {
        GeoPoint point = new GeoPoint(lat, lon);
        OverlayItem overlayItem = new OverlayItem(point, title, null);
        addOverlayItem(overlayItem);    
    } catch (Exception e) {
        // TODO: handle exception
        e.printStackTrace();
    }
}

@Override
protected boolean onTap(int index) {
    // TODO Auto-generated method stub
    String title = yourOverlays.get(index).getTitle();//display message when you touch your marker
    Toast.makeText(YourMapActivity.context, title, Toast.LENGTH_LONG).show();
    return super.onTap(index);
}

}`
