推荐答案

这里是一些代码绘制一个圆圈：

here is some code that draws a circle:

private class ProximityOverlay extends Overlay {

    public void draw(Canvas canvas, MapView mapview, boolean b) {
        // draw some stuff in here, like
        Paint paint = new Paint();
        paint.setAntiAlias(true);
        paint.setStrokeWidth(2.0f);
        double latitude = location.getLatitude();
        double longitude = location.getLongitude();
        Projection projection = mapView.getProjection();
        GeoPoint leftGeo = new GeoPoint((int) (latitude * 1e6),
                (int) (longitude * 1e6));
        Point left = new Point();
        projection.toPixels(leftGeo, left);

        paint.setColor(Color.parseColor("#00CCFF"));
        paint.setStyle(Style.FILL);
        canvas.drawCircle(left.x, left.y, 9, paint);
        paint.setColor(Color.parseColor("#003399"));
        paint.setStyle(Style.STROKE);
        canvas.drawCircle(left.x, left.y, 10, paint);



    }

您可以修改它绘制一个黑色矩形：

you can modify it to draw a black rectangle:

canvas.drawRect(left, top, right, bottom, paint);
