hi have implemented semi circle , draw line in border of semi circle not able draw line in below edges. how draw line in below edges. please give me suggestion. here code draw border:

 mrimwidth =40; mcontoursize = 1;         innercontour = new rectf(mcirclerectf.left + (mrimwidth / 2.0f)                         + (mcontoursize / 2.0f), mcirclerectf.top + (mrimwidth / 2.0f)                         + (mcontoursize / 2.0f), mcirclerectf.right                         - (mrimwidth / 2.0f) - (mcontoursize / 2.0f),                         mcirclerectf.bottom - (mrimwidth / 2.0f)                                 - (mcontoursize / 2.0f));                  outercontour = new rectf(mcirclerectf.left - (mrimwidth / 2.0f)                         - (mcontoursize / 2.0f), mcirclerectf.top - (mrimwidth / 2.0f)                         - (mcontoursize / 2.0f), mcirclerectf.right                         + (mrimwidth / 2.0f) + (mcontoursize / 2.0f),                         mcirclerectf.bottom + (mrimwidth / 2.0f)                                 + (mcontoursize / 2.0f));          canvas.drawarcoutercontour 160, 221, false, mpaint);                 canvas.drawarcinnercontour 160, 221, false, mpaint); 

mpaint code is:

mpaint = new paint();         mpaint.setantialias(true);         mpaint.setstyle(paint.style.stroke);         mpaint.setstrokewidth(10);         mpaint.setstrokecap(paint.cap.square);         mpaint.setcolor(mcircleprogresscolor);
