这篇文章主要介绍了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 的相关资料,需要的朋友可以参考下

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。

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

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：

mainactivity.java 部分
