使用Android动画类绘制五边形路径

Question

我有一个代码可以沿着圆形路径移动图像。但是我需要沿着另一条路径以五边形形状移动图像 下面给出了用于循环路径的代码

class CircularRotateAnimation
    (
    private val view: View              // view you want to animate
    , private val r: Float                // radius of circle
) : Animation() {
    private var cx: Float = 0.toFloat()
    private var cy: Float = 0.toFloat()           // center x,y position of circular path
    private var prevX: Float = 0.toFloat()
    private var prevY: Float = 0.toFloat()     // previous x,y position of image during animation
    private var prevDx: Float = 0.toFloat()
    private var prevDy: Float = 0.toFloat()

    override fun willChangeBounds(): Boolean {
        return true
    }

    override fun initialize(width: Int, height: Int, parentWidth: Int, parentHeight: Int) {
        val cxImage = width / 2
        val cyImage = height / 2
        cx = (view.left + cxImage).toFloat()
        cy = (view.top + cyImage).toFloat()

        // set previous position to center
        prevX = cx
        prevY = cy
    }

    protected override fun applyTransformation(interpolatedTime: Float, t: Transformation) {
        if (interpolatedTime == 0f) {
            t.getMatrix().setTranslate(prevDx, prevDy)
            return
        }

        val angleDeg = (interpolatedTime * 360f + 90) % 360
        val angleRad = Math.toRadians(angleDeg.toDouble()).toFloat()

        // r = radius, cx and cy = center point, a = angle (radians)
        val x = (cx + r * Math.cos(angleRad.toDouble())).toFloat()
        val y = (cy + r * Math.sin(angleRad.toDouble())).toFloat()

        val dx = prevX - x
        val dy = prevY - y

        prevX = x
        prevY = y

        prevDx = dx
        prevDy = dy
        t.matrix.setTranslate(dx, dy)
    }
}

如何使用applyTransformation覆盖方法绘制五边形路径。 或其他任何方法绘制五角形动画路径。
