从GitHub上下载的xRecyclerView的demo导入studio后出现这个异常
xRecyclerView源码地址：https://github.com/jianghejie/XRecyclerView
另外感谢这位博主的开源
这是导入GitHub上的demo出现的异常解决办法部分
导入的代码所报错误类型
解决办法：
版本gradle中修改
看看截图就解决问题是不是很简单，当然如果以后再GitHub上下载其他demo遇到这个错误时也可以通过这个办法解决
1：xRecyclerView的功能和RecyclerView大体差不多，但是他能解决多个滑动组合到一个页面会出现加载缓慢，卡顿等。
特别好的是比如下面这个截图只需要设置头视图即可不需要写另外的布局文件
带头视图的xrecyclerview
代码如下：
