Y轴旋转动画

实现方式一：

ObjectAnimator catAnimation = ObjectAnimator.ofFloat(catIv, "rotationY", 0f, 360f);
                catAnimation.setDuration(1000);
                catAnimation.setInterpolator(new LinearInterpolator());
                catAnimation.addListener(new Animator.AnimatorListener() {
                    @Override
                    public void onAnimationStart(Animator animation) {
                    }

                    @Override
                    public void onAnimationEnd(Animator animation) {

                    }

                    @Override
                    public void onAnimationCancel(Animator animation) {

                    }

                    @Override
                    public void onAnimationRepeat(Animator animation) {

                    }
                });
                catAnimation.start();
                

动画后还原： 1：

AnimatorSet animatorSet = new AnimatorSet();
ObjectAnimator animator = ObjectAnimator.ofFloat(catIv, "rotationY", 180f, 0f);
animator.setDuration(0);
animatorSet.playSequentially(catAnimation,animator);
animatorSet.start();

2：

 catIv.setRotationY(0);

实现方式二：

int centerX = catIv.getWidth() / 2;
int centerY = catIv.getHeight() / 2;
Rotate3dAnimation rotate3dAnimation = new Rotate3dAnimation(0f, 180f, centerX, centerY, 0, false);
rotate3dAnimation.setDuration(1000);
rotate3dAnimation.setFillBefore(true);
catIv.startAnimation(rotate3dAnimation);

动画后还原：

rotate3dAnimation.setFillBefore(true);
