Interpolator导致 的动画执行实际效果

AccelerateInterpolator： 在动画开始的地方速率改变比较慢，然后开始加速

ObjectAnimator oa = ObjectAnimator.ofFloat(view, "translationY", 0f,1100f);
        oa.setDuration(500);
        //设置加速插值器---参数值越大，加速度越大
        oa.setInterpolator(new AccelerateInterpolator(5));
                oa.start();

AccelerateDecelerateInterpolator ：在动画开始与结束的地方速率改变比较慢，在中间的时候加速

ObjectAnimator oa = ObjectAnimator.ofFloat(view, "translationY", 0f,1100f);
        oa.setDuration(500);
        oa.setInterpolator(new AccelerateDecelerateInterpolator());
                oa.start();

AnticipateInterpolator :开始的时候向后移动，再向前移动，类似荡秋千，回荡再往前

ObjectAnimator oa = ObjectAnimator.ofFloat(view, "translationY", 0f,1100f);
        oa.setDuration(500);
        //设置回荡秋千插值器---参数值越大，回荡效果越大
        oa.setInterpolator(new AnticipateInterpolator(8));
                oa.start();

AnticipateOvershootInterpolator ：开始的时候向后然后向前甩一定值后返回最后的值

ObjectAnimator oa = ObjectAnimator.ofFloat(view, "translationY", 0f,1100f);
        oa.setDuration(500);
        oa.setInterpolator(new OvershootInterpolator());
                oa.start();

BounceInterpolator：动画结束的时候弹起

ObjectAnimator oa = ObjectAnimator.ofFloat(view, "translationY", 0f,1100f);
        oa.setDuration(500);
                oa.setInterpolator(new BounceInterpolator());
                oa.start();

CycleInterpolator：动画循环播放特定的次数，速率改变沿着正弦曲线

ObjectAnimator oa = ObjectAnimator.ofFloat(view, "translationY", 0f,1100f);
        oa.setDuration(500);
        //设置正弦周期变化插值器---参数值为循环次数
        oa.setInterpolator(new CycleInterpolator(4));
                oa.start();

DecelerateInterpolator ：在动画开始的地方先快后慢减速结束

ObjectAnimator oa = ObjectAnimator.ofFloat(view, "translationY", 0f,1100f);
        oa.setDuration(500);
        oa.setInterpolator(new DecelerateInterpolator());
                oa.start();

OvershootInterpolator：向前甩一定距离后再回到原来位置

ObjectAnimator oa = ObjectAnimator.ofFloat(view, "translationY", 0f,1100f);
        oa.setDuration(500);
        oa.setInterpolator(new OvershootInterpolator());
                oa.start();
