Java 如何在自定义视图中使用的android画布中居中任何自定义路径（形状）？

我使用pathClass创建了一个自定义的圆形方形形状，然后在自定义视图的画布中绘制自定义路径。当我给视图增加更多的高度时，比如说300高和100宽，但是当宽度更大时，它会转到顶部而不是视图的中心，自定义形状会转到左侧。我不知道问题是什么，我认为问题出在x，y。以下是路径代码：

public static Path roundRectSquare(int height,int width,
                          float topLeftRadius,float topRightRadius,
                          float bottomRightRadius,float bottomLeftRadius){
        Path path = new Path();
        RectF bl = new RectF(0, height -2* bottomLeftRadius,2* bottomLeftRadius, height);
        RectF br = new RectF(width -2* bottomRightRadius, height -2* bottomRightRadius, width, height);
        RectF tl = new RectF(0,0,2* topLeftRadius,2* topLeftRadius);
        RectF tr = new RectF(width -2* topRightRadius,0, width,2* topRightRadius);
        path.reset();
        path.moveTo(x + topLeftRadius, y);
        path.lineTo(width - topRightRadius, y);
        path.arcTo(tr,-90,90);
        path.lineTo(width, y + topRightRadius);
        path.lineTo(width, height - bottomRightRadius);
        path.arcTo(br,0,90);
        path.lineTo(width - bottomRightRadius, height);
        path.lineTo(x + bottomLeftRadius, height);
        path.arcTo (bl,90,90);
        path.lineTo(x, height - bottomLeftRadius);
        path.lineTo(x,y + topLeftRadius);
        path.arcTo(tl,90,180);
        path.close();
        return path;
    }

路径中的

代码x和y是getWidth/2和getHeight/2

我在自定义视图绘制方法代码中使用了此路径：

 @Override
    public void draw(Canvas canvas) {
        path = new Path();
        boxPaint =new Paint();
        int side = Math.min(this.getHeight(),this.getWidth());
        boxPaint.setStyle(Paint.Style.FILL);
        boxPaint.setColor(Color.YELLOW);
        path = roundRectSquare(side,side,30,20,50,10);
        canvas.drawPath(path,boxPaint);
        super.draw(canvas);
    }

那么有没有办法解决这个问题呢
