拖拽排序，长按显示删除按钮

参考项目:RecycleView&ItemTouchHelp，更改：点击编辑按钮删除改为长按显示删除按钮，解决长按拖动删除时position错乱问题。*

参考项目： https://github.com/huyue05/ItemTouchHelper-RecycleView

以下是演示图片

最近要做一个可以拖拽排序、可以长按显示删除按钮、还有分组展示item等要求的recycleview或gridview
开始不想重复找轮子，就在网上找了很多，都不能满足公司的要求，最后找了一个又自己改了一些，才满足要求。
解决隐藏问题：长按拖动后，在没有点完成前又点了删除，会删除错误的item
原因是拖动完还没有刷新整个控件的话position不会变化，所以拖动完删除position没变
最后重写了RecycleView，在里面加上了onTouchEvent监听手指松开事件，松开后刷新控件，position就更改过来了

如果有好的解决办法请联系我，谢谢！
