        Paint paint = new Paint();

        paint.setStrokeWidth(40f);//布局里一般会写1dp，此处宽度不做限制
        paint.setColor(getResources().getColor(R.color.bg_divider_main));
        Path path = new Path();
        path.moveTo(0, 0);//起始坐标
        path.lineTo(0,500);//终点坐标
        PathEffect effects = new DashPathEffect(new float[]{5,5,5,5},1);//设置虚线的间隔和点的长度,数组的含义：先画5实线，再空5，再画5实线，再空5
        paint.setPathEffect(effects);  
        canvas.drawPath(path, paint);  
    }
