    <p>I am trying to override onTap function for an overlay of Mapview which contains a set of lines drawn using a Path. I was wondering if there is any specific overlay designed which has the onTap for lines? </p> <p>My overlay looks like this: </p> <pre><code>public class MyPathOverlay extends Overlay { MapView map; Projection projection; ArrayList&lt;Pair&lt;GeoPoint, Integer&gt;&gt; pointsList; // Set of points and the // color of the line // starting from this point public MyPathOverlay(MapView contextMap, ArrayList&lt;Pair&lt;GeoPoint, Integer&gt;&gt; points) { map = contextMap; projection = map.getProjection(); pointsList = points; } @Override public void draw(Canvas canvas, MapView mapView, boolean shadow) { super.draw(canvas, mapView, shadow); if (shadow == false &amp;&amp; pointsList !=null) { for (int i = 0; i &lt; pointsList.size() - 1; i++) { Paint paint = new Paint(); paint.setDither(true); Pair&lt;GeoPoint, Integer&gt; p1 = pointsList.get(i); GeoPoint gp1 = p1.first; paint.setColor(p1.second); GeoPoint gp2 = pointsList.get(i + 1).first; paint.setStyle(Paint.Style.FILL_AND_STROKE); paint.setStrokeJoin(Paint.Join.ROUND); paint.setStrokeCap(Paint.Cap.ROUND); paint.setStrokeWidth(5); Point point1 = new Point(); Point point2 = new Point(); projection.toPixels(gp1, point1); projection.toPixels(gp2, point2); Path path = new Path(); path.moveTo(point2.x, point2.y); path.lineTo(point1.x, point1.y); canvas.drawPath(path, paint); } } } @Override public boolean onTap(GeoPoint p, MapView mapView) { return super.onTap(p, mapView); } </code></pre> <p>}</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.
