    <p>I am attempting to draw a custom Drawable overlay on a MapView. I use a custom class that extends Drawable to draw the circle on a canvas. Then I pass a radius variable to it and add it to an ItemizedOverlay which gets applied to the MapView.</p> <p>So far it is working out pretty well, but for some reason, the canvas.drawCircle method is drawing a transparent circle with what looks like an ellipse inside of it, and I can't, for the life of me, figure out what is causing it. I do want the circle to be transparent, but I don't want this ellipse thing inside of it.</p> <p>Here is the custom Drawable class:</p> <pre><code>import android.graphics.Canvas; import android.graphics.ColorFilter; import android.graphics.Paint; import android.graphics.drawable.Drawable; public class PileDrawable extends Drawable { private static final Paint paint = new Paint(); int rad; public PileDrawable(int radius) { paint.setARGB(100, 0, 255, 0); paint.setAntiAlias(false); paint.setStyle(Paint.Style.FILL); rad=radius; } @Override public void draw(Canvas canvas) { canvas.drawCircle(0, 0, rad, paint); } @Override public int getOpacity() { return 0; } @Override public void setAlpha(int alpha) { } @Override public void setColorFilter(ColorFilter cf) { } } </code></pre> <p>This is kind of what it looks like, ignore my lack of MS paint skills...</p> <p><a href="http://img222.imageshack.us/img222/4356/circleellipse.png" rel="nofollow">http://img222.imageshack.us/img222/4356/circleellipse.png</a></p> <p>I have a lingering feeling that the problem occurs when I apply the bounds to the Drawable.</p> <pre><code>PileDrawable pd = new PileDrawable((int)(mapView.getProjection().metersToEquatorPixels(Radius) * (1/ Math.cos(Math.toRadians(point.getLatitudeE6()))))); pd.setBounds(0,0,pd.getIntrinsicWidth(),pd.getIntrinsicHeight()); //HERE? </code></pre> <p>So, any ideas?</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.
