android - 像网易贵金属安装之后的导航页动画如何做到不卡的

Question

我用了属性动画，但是在内存低的手机上跑了一下感觉卡卡的，但是贵金属的就不卡
,属性动画和补间动画相比效率上比较差吗，
这是我的代码

 private void setFirstAnimation() {
        if (firstAnimationState == 0) {
            firstAnimationState = 1;
            ObjectAnimator anim1 = ObjectAnimator.ofFloat(iv_first_calculator,
                    "x", PhoneParameterUtils.getScreenWidth() / 2f - 200f - 323f,
                    (PhoneParameterUtils.getScreenWidth() / 2f) - AppTools.dip2px(100)).setDuration(400);
            anim1.addListener(new Animator.AnimatorListener() {
                @Override
                public void onAnimationStart(Animator animator) {

                }

                @Override
                public void onAnimationEnd(Animator animator) {
                    AnimatorSet set = new AnimatorSet();

                    ObjectAnimator anim2 = ObjectAnimator.ofFloat(iv_first_ball,
                            "x", PhoneParameterUtils.getScreenWidth() / 2,
                            PhoneParameterUtils.getScreenWidth() / 2 + AppTools.dip2px(40)).setDuration(400);

                    ObjectAnimator anim3 = ObjectAnimator.ofFloat(iv_first_ball,
                            "y", PhoneParameterUtils.getScreenHeight() / 2 - AppTools.dip2px(120),
                            PhoneParameterUtils.getScreenHeight() / 2 - AppTools.dip2px(150)).setDuration(400);

                    set.playTogether(anim2, anim3);
                    set.addListener(new Animator.AnimatorListener() {

                            set.playSequentially(anim4, anim5, anim6);
                            iv_first_man.setVisibility(View.VISIBLE);
