Android实现仿网易今日头条等自定义频道listview 或者grideview等item上移到另一个view中

概述我这里只是简单的用了两个listview来实现的，先上效果图。比较粗糙。预留了自定义的空间。

我这里只是简单的用了两个ListvIEw来实现的，先上效果图。比较粗糙。预留了自定义的空间。

思路：

从上图应该可以看的出来。就是上下两个ListvIEw。点击下面的ltem。会动态的移动到上一个ListvIEw的最后。上面的ListvIEw 为ListvIEw1,下面的为ListvIEw2. 点击ListvIEw2,获取到vIEw ，设置一个动画，移动到ListvIEw1,ListvIEw2中删除被点的item。ListvIEw1中新增一个。

上代码：

两个adapter部分。两个差不都。传一个
