最近学习RecyclerView,使用eclipse引用RecyclerView，编写完demo后编译没有问题，一运行就挂掉，错误如下：

试了很多方法都不行，整了半天，终于搞定，原来在eclipse中使用RecyclerView只能导入API21.0.0中的包才可以使用。

解决办法：进入sdkextrasandroidm2repositorycomandroidsupportrecyclerview-v721.0.0目录，找到recyclerview-v7-21.0.0.aar这个文件。用解压软件解压此文件里面有classes.jar，把这个jar包放到项目中的libs文件下即可。这个jar包就是RecyclerView要使用的，可以给它改个名字例如android-support-v7-recyclerview.jar , 便于查看。
