Android Custom Faux 360Root watermark effect

very simple one effect. I was straight.

The code is not detailed, put the key code on the line.
  @Override     protected void OnDraw (canvas canvas) {        Super.ondraw (canvas); & nbsp       Canvas.save ();        canvas.drawcircle (WIDTH/2, HEIGHT/2, Interradius, Inter Circlepaint);        if (list! = null  && list.size () > 0) {            int listsize = List.size ();            int removeindex =-1;    & nbsp       for (int i = 0; i < listsize; i + +) {                CIRC Leinfo Mcircleinfo = List.get (i);                Outpaint.setcolor (mcircleinfo.co LOR);                Outpaint.setalpha (255-mcircleinfo.radius  * 255 &nbsp ;/Outcirclemaxradius);                Mcircleinfo.radius = Mcircleinfo.radius + 1 ;    &NBsp           if (Mcircleinfo.radius > Outcirclemaxradius) {          &NBS P         Removeindex = i;               }else {                    canvas.drawcircle (WIDTH/2, HEIGHT/2, Mcircleinfo.radius, OUTPA int);               }           }    &NB Sp       if (Removeindex > 0) {                List.remove (Removein Dex);                Removeindex =-1;           }        }        Canvas.restore ();
if (list = = null) {Animatorcontrol (); }
Postinvalidate (); }
