    <p>I need to draw something like this which will be painted and have little transparency</p> <p>Also it needs to be clickable (onTouch event etc)</p> <p><img src="https://i.stack.imgur.com/8Ons4.png" alt="enter image description here"></p> <p>I know that in API v1 you have to use Overlay and extend it using canvas and some mathematics. What is easiest way to do it in Google Map API v2? </p> <p>PS: Radius is variable.</p> <p>(For further reference) EDIT 1:</p> <p>I implemented CanvasTileProvider subclass and override its onDraw() method:</p> <pre><code>@Override void onDraw(Canvas canvas, TileProjection projection) { // TODO Auto-generated method stub LatLng tempLocation = moveByDistance(mSegmentLocation, mSegmentRadius, mSegmentAngle); DoublePoint segmentLocationPoint = new DoublePoint(0, 0); DoublePoint tempLocationPoint = new DoublePoint(0, 0); projection.latLngToPoint(mSegmentLocation, segmentLocationPoint); projection.latLngToPoint(tempLocationPoint, tempLocationPoint); float radiusInPoints = FloatMath.sqrt((float) (Math.pow( (segmentLocationPoint.x - tempLocationPoint.x), 2) + Math.pow( (segmentLocationPoint.y - tempLocationPoint.y), 2))); RectF segmentArea = new RectF(); segmentArea.set((float)segmentLocationPoint.x - radiusInPoints, (float)segmentLocationPoint.y - radiusInPoints, (float)segmentLocationPoint.x + radiusInPoints, (float)segmentLocationPoint.y + radiusInPoints); canvas.drawArc(segmentArea, getAdjustedAngle(mSegmentAngle), getAdjustedAngle(mSegmentAngle + 60), true, getOuterCirclePaint()); } </code></pre> <p>Also, I added this from MapActivity:</p> <pre><code>private void loadSegmentTiles() { TileProvider tileProvider; TileOverlay tileOverlay = mMap.addTileOverlay( new TileOverlayOptions().tileProvider(new SegmentTileProvider(new LatLng(45.00000,15.000000), 250, 30))); } </code></pre> <p>Now I'm wondering why my arc isn't on map?</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.
