/**
 * PtrFrameLayout演示程序1
 * 6个参数可配置:
 *  阻尼系数：默认1.7f，越大，感觉下拉时越吃力。
 *  触发刷新时移动的位置比例：默认，1.2f，移动达到头部高度1.2倍时可触发刷新操作。
 *  回弹延时：默认 200ms，回弹到刷新高度所用时间
 *  头部回弹时间：默认1000ms
 *  刷新是保持头部：默认值 true.
 *  下拉刷新 / 释放刷新，默认为释放刷新
 * 问题bug解决：
 *  ViewPager滑动冲突: disableWhenHorizontalMove()
 *  长按LongPressed, setInterceptEventWhileWorking()
 * 参考文档：
 * https://github.com/liaohuqiu/android-Ultra-Pull-To-Refresh/blob/master/README-cn.md
