Paint mPaint = new Paint();
mPaint.setDither(true);
mPaint.setColor(Color.RED);
mPaint.setStyle(Paint.Style.FILL_AND_STROKE);
mPaint.setStrokeJoin(Paint.Join.ROUND);
mPaint.setStrokeCap(Paint.Cap.ROUND);
mPaint.setStrokeWidth(2);
Point p1 = new Point();
Point p2 = new Point();
Path path = new Path();
Projection projection = mapv.getProjection();
for(int i=0; i<listOfPoints.size()-2; i++)
{
// System.out.println(listOfPoints.get(i).getLatitudeE6()+" "+ listOfPoints.get(i).getLatitudeE6());
projection.toPixels(listOfPoints.get(i), p1);
projection.toPixels(listOfPoints.get(i+1), p2);
path.moveTo(p2.x, p2.y);
path.lineTo(p1.x,p1.y);
}
canvas.drawPath(path, mPaint);
