最近學習RecyclerView,使用eclipse引用RecyclerView，編寫完demo後編譯沒有問題，一執行就掛掉，錯誤如下：

試了很多方法都不行，整了半天，終於搞定，原來在eclipse中使用RecyclerView只能匯入API21.0.0中的包才可以使用。
解決辦法：進入sdk\extras\android\m2repository\com\android\support\recyclerview-v7\21.0.0目錄，找到recyclerview-v7-21.0.0.aar這個檔案。用解壓軟體解壓此檔案裡面有classes.jar，把這個jar包放到專案中的libs檔案下即可。這個jar包就是RecyclerView要使用的，可以給它改個名字例如android-support-v7-recyclerview.jar
, 便於檢視。
最近升級了SDK發現sdk\extras\android\m2repository\com\android\support\recyclerview-v7\21.0.0這個目錄找不到了，所以把之前的jar包傳到了csdn的伺服器上，需要的可以到這下載：
注意注意注意：我提供的這個包是15年5.0剛釋出的時候保留的包，當時recyclerview這個控制元件也是剛剛推出，功能很強大，但是也有許多不完善的地方，在後期的sdk更新中官方可能更新了recyclerview的api，使其更加完善。但這也導致大家在用我的包並在21以上的sdk編譯時有些方法不支援，比如 addOnScrollListener和android.support.v7.widget.helper.ItemTouchHelper 。
如果你沒有用到這些方法又必須使用eclipse可以繼續使用我的包，如果必須用這些方法，建議大家放棄使用eclipse，換成使用as開發。
