自动下拉，自动收缩

可以应用于下拉刷新中的一些控件结合使用起来

收缩动画

private class CollapseAnimation extends Animation {        private final int mStartHeight;        private final int mDistance;        public CollapseAnimation() {            super();            int endHeight;            mStartHeight = 0;            endHeight = refreshTargetTop;            setMargin(mStartHeight);            mDistance = endHeight - mStartHeight;            setDuration(300);            setAnimationListener(new CollapseAnimationListener());        }        @Override        protected void applyTransformation(float interpolatedTime, Transformation t) {            setMargin(mStartHeight + Math.round(mDistance * interpolatedTime));        }    }

自动下拉

private class ExpandAnimation extends Animation {        private final int mStartHeight;        private final int mDistance;        public ExpandAnimation() {            super();            int endHeight;            mStartHeight = refreshTargetTop;            endHeight = 0;            setMargin(mStartHeight);            mDistance = endHeight - mStartHeight;            setDuration(300);            setAnimationListener(new ExpandAnimationListener());        }        @Override        protected void applyTransformation(float interpolatedTime, Transformation t) {            setMargin(mStartHeight + Math.round(mDistance * interpolatedTime));        }    }
