我想添加一个旋转drawable作为一个按钮 drawableRight 但它不旋转 . 这是我试图使用的代码 .

Drawable loader = ContextCompat.getDrawable(getActivity(), R.drawable.ic_rotate_right);

                ObjectAnimator rotateAnim = ObjectAnimator.ofFloat(loader,
                        "rotation", 0f, 360f);
                rotateAnim.setDuration(500);
                rotateAnim.setRepeatCount(ValueAnimator.INFINITE);
                rotateAnim.setRepeatCount(ValueAnimator.RESTART);
                rotateAnim.start();

                simpleButton.setCompoundDrawablesWithIntrinsicBounds(null, null, loader, null);

请问你知道如何实现这一目标吗？

Note: drawable是一个矢量drawable .

android objectanimator
