    <p>I am triyng to add multiple marker on google map. Here is my code section</p> <pre><code>public class GoogleMap extends MapView { MapController mc; MapView mapView; GeoPoint p; @Override public void onCreate(Bundle savedInstanceState) { .... double lat = Double.parseDouble(bundle.getString("paramLat")); double lng = Double.parseDouble(bundle.getString("paramLong")); mc = mapView.getController(); p = new GeoPoint( (int) (lat * 1E6), (int) (lng * 1E6)); mc.animateTo(p); mc.setZoom(17); //---Add a location marker--- MapOverlay mapOverlay = new MapOverlay(); List&lt;Overlay&gt; listOfOverlays = mapView.getOverlays(); listOfOverlays.clear(); listOfOverlays.add(mapOverlay); mapView.invalidate(); } class MapOverlay extends com.google.android.maps.Overlay { @Override public boolean draw(Canvas canvas, MapView mapView, boolean shadow, long when) { super.draw(canvas, mapView, shadow); //---translate the GeoPoint to screen pixels--- Point screenPts = new Point(); mapView.getProjection().toPixels(p, screenPts); //---add the marker--- Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.pushpin); canvas.drawBitmap(bmp, screenPts.x, screenPts.y-50, null); return true; } } </code></pre> <p>I have two question here. When i tried to add only one marker, it works but draw method is invoked many times. But why? and when is it invoked? </p> <p>The second question is how can i add new marker. I created second geoPoint named p2 and after that what should i do? Thank you very much.</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.
