制作可滑动的layout extends FrameLayout，看上去是一个可上下滑动的日期列表，每个日期下显示相关的条目，有点像时间轴的感觉。初始化dragHelper，对拖动的view进行操作，ExpandableListView做的android时间轴TimeLine-masterchild有左右滑动的效果，另外还可设置是否有回弹效果，并进行相关的操作（如：编辑、删除、置顶等）,(RecycleView 多种type实现)，包含child的滑动效果。 　　关于滑动距离：如果启动效果，则可滑动3/2倍菜单宽度的距离 　　重写OnClickListener会导致关闭失效 　　 拖动中，可根据offset 进行其他动画，并定义了滑动监听函数。
