Android 将弯曲路径设置为另一条路径的动画

我必须为曲线路径设置动画，使其指向路径点的其他位置。我使用的是cubicTo和以下五点：

    Path mainFillPath = new Path();
    mainFillPath.reset();
    mainFillPath.moveTo(leftPointX, leftPointY);

    mainFillPath.cubicTo(leftPointX, leftPointY, centerPointX1, centerPointY1, centerPointX, centerPointY);
    mainFillPath.cubicTo(centerPointX, centerPointY, centerPointX2, centerPointY2, rightPointX, rightPointY);

    mainFillPath.lineTo(rightPointX, 0);
    mainFillPath.lineTo(0, 0);

    mainFillPath.close();

    final ObjectAnimator anim = ObjectAnimator.ofObject(this, "buttonLoc",
            new PathEvaluator(), path.getPoints().toArray());
    anim.setDuration(2000);

我正在画布上绘画

canvas.drawPath（myPath，paint）

我必须使用哪位动画师才能获得此波浪效果：


我在一些项目中尝试过ObjectAnimator和ValueAnimator。其中之一是使用PathEvaluator（）在特定路径上设置移动按钮的动画，如下所示：

    Path mainFillPath = new Path();
    mainFillPath.reset();
    mainFillPath.moveTo(leftPointX, leftPointY);

    mainFillPath.cubicTo(leftPointX, leftPointY, centerPointX1, centerPointY1, centerPointX, centerPointY);
    mainFillPath.cubicTo(centerPointX, centerPointY, centerPointX2, centerPointY2, rightPointX, rightPointY);

    mainFillPath.lineTo(rightPointX, 0);
    mainFillPath.lineTo(0, 0);

    mainFillPath.close();

    final ObjectAnimator anim = ObjectAnimator.ofObject(this, "buttonLoc",
            new PathEvaluator(), path.getPoints().toArray());
    anim.setDuration(2000);
