룰렛를 구현중인데요

룰렛에 당첨이 되었을 때 그 당첨된 항목을 토스트로 뿌려주려고 합니다.

하지만 그 당첨된 룰렛의 값을 어찌 가져와야 할지 모르겠네요

private void drawRoulette(Canvas canvas)
  {
   int centerX = this.getWidth() / 2;
   int centerY = this.getHeight() / 2;
   int roulWidth = this.getWidth() - 10;
   //int roulHeight = roulWidth;
   int radius = roulWidth / 2;
   RectF rt = new RectF(centerX-radius, centerY-radius, centerX+radius, centerY+radius);
   
   float SliceAngle = 360.0f / mSlices.size();
   
   double textStartX = radius - 8;
   double textStartY = 0.0;
   //int PrevColorIdx = -1;
   int CurColorIdx = -1;
   for(int i=0; i<mSlices.size(); startAngle+=SliceAngle, i++)
   {
   // do {
   //  CurColorIdx = Rnd.nextInt(ColorList.length);
   // } while(CurColorIdx == PrevColorIdx);
    CurColorIdx = i%ColorList.length;
    Pnt.setColor(ColorList[CurColorIdx]);
    Pnt.setStyle(Paint.Style.FILL);
    canvas.drawArc(rt, startAngle, SliceAngle, true, Pnt);
        
    float curHalfAngle = (startAngle + (SliceAngle / 2));
    
    // x' = x * cosθ + y * (-sinθ)
    double txtStartX = Math.cos(Math.toRadians(curHalfAngle)) * textStartX;
    txtStartX = txtStartX + Math.sin(Math.toRadians(curHalfAngle)) * textStartY * (-1);
    txtStartX += centerX;
    
    // y' = x * sinθ + y * cosθ
    double txtStartY= Math.sin(Math.toRadians(curHalfAngle)) * textStartX;
    txtStartY = txtStartY + Math.cos(Math.toRadians(curHalfAngle)) * textStartY;
    txtStartY += centerY;
    
    textPath.reset();
    Pnt.setColor(Color.WHITE);
    Pnt.setStrokeWidth(3);
    textPath.moveTo((int)txtStartX, (int)txtStartY);
    textPath.lineTo(centerX, centerY);    
    canvas.drawTextOnPath(mSlices.get(i), textPath, 0, 0, Pnt);
    
   }
   textPath.reset();
   textPath.moveTo(centerX, centerY - radius + 15);
   textPath.lineTo(centerX + 10, centerY - radius - 15);
   textPath.lineTo(centerX - 10, centerY - radius - 15);
   textPath.lineTo(centerX, centerY - radius + 15);
   Pnt.setStrokeWidth(1);
   Pnt.setColor(0xFF555555);
   canvas.drawPath(textPath, Pnt);
  }

이런식으로 canvas로 부채꼴를 그리고 거기에 글씨를 써넣는 방식으로 구현했습니다.

여기서 어떻게 하면 당첨된 항목을 가져올수 있을까요?

아 정말 힘드네요 ㅜㅜ
