    <p>I have a class :</p> <pre><code>class MapItemizedOverlay extends com.google.android.maps.ItemizedOverlay&lt;OverlayItem&gt; { private Context context; private ArrayList items = new ArrayList(); public MapItemizedOverlay(Context aContext, Drawable marker) { super(boundCenterBottom(marker)); context = aContext; } public void addOverlayItem(OverlayItem item) { items.add(item); populate(); } @Override protected OverlayItem createItem(int i) { return (OverlayItem) items.get(i); } @Override public int size() { return items.size(); } @Override protected boolean onTap(int index) { OverlayItem item = (OverlayItem) items.get(index); AlertDialog.Builder dialog = new AlertDialog.Builder(context); dialog.setTitle(item.getTitle()); dialog.setMessage(item.getSnippet()); dialog.show(); return true; } @Override public boolean onTap (final GeoPoint p, final MapView mapView) { Geocoder geoCoder = new Geocoder(getBaseContext(), Locale.getDefault()); try { List&lt;Address&gt; addresses = geoCoder.getFromLocation(p.getLatitudeE6() / 1E6, p.getLongitudeE6() / 1E6, 1); String address = ""; if (addresses.size() &gt; 0) { for (int i=0; i&lt;addresses.get(0).getMaxAddressLineIndex(); i++) address += addresses.get(0).getAddressLine(i) + "\n"; } address.cancel(); address.setText(address); address.show(); } catch (IOException e) { e.printStackTrace(); } return true; } } </code></pre> <p>I add some overlays on the map with the function:</p> <pre><code>private void initialiseOverlays() { // Create an ItemizedOverlay to display a list of markers Drawable defaultMarker = getResources().getDrawable(R.drawable.marker); MapItemizedOverlay mapItemizedOverlay = new MapItemizedOverlay(this, defaultMarker); mapItemizedOverlay.addOverlayItem(new OverlayItem(new GeoPoint((int) (12.345678 * 1E6), (int) (23.456789 * 1E6)), "Point 1", "some-random-text")); mapItemizedOverlay.addOverlayItem(new OverlayItem(new GeoPoint((int) (89.012345 * 1E6), (int) (67.890123 * 1E6)), "Point number 2", "more-random-text")); // Add the overlays to the map mapView.getOverlays().add(mapItemizedOverlay); } </code></pre> <p>If only one of the onTap functions is defined everything works fine - I can either get the address if I click somewhere over the map or I can get a dialog with the place's title and content if I click on the icon over the place. But I want to have both of the functions working together, the application to detect if the click was over an empty place on the map or over a marker(the drawable set) and show it's information. How can I achieve this?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
