报错：Binary XML file line #7: Error inflating class android.support.v7.widget.RecyclerView

近期学习RecyclerView,使用eclipse引用RecyclerView。编写完demo后编译没有问题，一执行就挂掉，错误例如以下：

试了非常多方法都不行，整了半天，最终搞定，原来在eclipse中使用RecyclerView仅仅能导入API21.0.0中的包才干够使用。

解决的方法：进入sdk\extras\android\m2repository\com\android\support\recyclerview-v7\21.0.0文件夹，找到recyclerview-v7-21.0.0.aar这个文件。

用解压软件解压此文件中面有classes.jar，把这个jar包放到项目中的libs文件下就可以。这个jar包就是RecyclerView要使用的。能够给它改个名字比如android-support-v7-recyclerview.jar
, 便于查看。

近期升级了SDK发现sdk\extras\android\m2repository\com\android\support\recyclerview-v7\21.0.0这个文件夹找不到了。所以把之前的jar包传到了csdn的server上，须要的能够到这下载： http://download.csdn.net/detail/u010351494/9232327

注意注意注意：我提供的这个包是15年5.0刚公布的时候保留的包，当时recyclerview这个控件也是刚刚推出。功能非常强大。可是也有很多不完好的地方，在后期的sdk更新中官方可能更新了recyclerview的api，使其更加完好。但这也导致大家在用我的包并在21以上的sdk编译时有些方法不支持。比方 addOnScrollListener和android.support.v7.widget.helper.ItemTouchHelper。

假设你没实用到这些方法又必须使用eclipse能够继续使用我的包，假设必须用这些方法。建议大家放弃使用eclipse，换成使用as开发。
