* Intro: 解决 滑动冲突的 ViewPager |

* <p> |
||||
* 因为ViewPager 和 SwipMenuLayout都是水平方向滑动的控件。 |
||||
* 所以在一起使用时会有冲突， |
||||
* 使用本控件(CstViewPager)，可以在ViewPager的第一页使用左滑。在ViewPager的最后一页使用右滑菜单。 |

* 【Item侧滑删除菜单】 |
||||
* 继承自ViewGroup，实现滑动出现删除等选项的效果， |
||||
* 思路：跟随手势将item向左滑动， |
||||
* 在onMeasure时 将第一个Item设为屏幕宽度 |
||||
* 【解决屏幕上多个侧滑删除菜单】：内设一个类静态View类型变量 ViewCache，存储的是当前正处于右滑状态的CstSwipeMenuItemViewGroup， |
||||
* 每次Touch时对比，如果两次Touch的不是一个View，那么令ViewCache恢复普通状态，并且设置新的CacheView |
||||
* 只要有一个侧滑菜单处于打开状态， 就不给外层布局上下滑动了 |
||||
* <p/> |
||||
* 平滑滚动使用的是Scroller,20160811，最新平滑滚动又用属性动画做了，因为这样更酷炫(设置加速器不同) |
||||
* <p/> |
||||
* 20160824,fix 【多指一起滑我的情况】：只接第一个客人(使用一个类静态布尔变量) |
||||
* other: |
||||
* 1 菜单处于侧滑时，拦截长按事件 |
||||
* 2 解决侧滑时 点击 的冲突 |
||||
* 3 通过 isIos 变量控制是否是IOS阻塞式交互，默认是打开的。 |
||||
* 4 通过 isSwipeEnable 变量控制是否开启右滑菜单，默认打开。（某些场景，复用item，没有编辑权限的用户不能右滑） |
||||
* 5 2016 09 29 add,，通过开关 isLeftSwipe支持左滑右滑 |
||||
* 6 2016 10 21 add , 增加viewChache 的 get()方法，可以用在：当点击外部空白处时，关闭正在展开的侧滑菜单。 |
||||
* 7 2016 10 22 fix , 当父控件宽度不是全屏时的bug。 |
||||
* 2016 10 22 add , 仿QQ，侧滑菜单展开时，点击除侧滑菜单之外的区域，关闭侧滑菜单。 |
||||
* 8 2016 11 03 add,判断手指起始落点，如果距离属于滑动了，就屏蔽一切点击事件。 |
||||
* 9 2016 11 04 fix 长按事件和侧滑的冲突。 |
||||
* 10 2016 11 09 add,适配GridLayoutManager，将以第一个子Item(即ContentItem)的宽度为控件宽度。 |
||||
* 11 2016 11 14 add,支持padding,且后续计划加入上滑下滑，因此不再支持ContentItem的margin属性。 |
||||
* 2016 11 14 add,修改回弹的动画，更平滑。 |
||||
* 2016 11 14 fix,微小位移的move不回回弹的bug |
||||
* 2016 11 18,fix 当ItemView存在高度可变的情况 |
||||
* 2016 12 07,fix 禁止侧滑时(isSwipeEnable false)，点击事件不受干扰。 |
||||
* 2016 12 09,fix ListView快速滑动快速删除时，偶现菜单不消失的bug。 |
