android - ObjectAnimator动画报错

Question

最近学习ObjectAnimator动画，本想让图片按着Path的路径跑起来，但是运行起来报错java.lang.NoSuchMethodError: android.animation.ObjectAnimator.ofFloat，求大神指导一二，不胜感激！！！

    Path path = new Path();
    path.moveTo(0, 0);
    path.lineTo(400, 0);
    path.lineTo(400, 400);
    path.quadTo(600, 600, 0, 400);
    ObjectAnimator animator = ObjectAnimator.ofFloat(imageView,View.X,View.Y,path);
    animator.setDuration(4000);
    animator.start();

Answer 1

ofFloat was added after API 11. If you want to be compatible with lower versions, you can use the NineOldAndroids library
