Recyclerview運(yùn)行找不到類

在引用RecyclerView類的時(shí)候編譯不報(bào)錯(cuò)，運(yùn)行時(shí)報(bào)錯(cuò)找不到類。
該情況只會(huì)在Eclipse中會(huì)出現(xiàn)，目測(cè)是ADT的bug：

網(wǎng)上大部分帖子對(duì)于這個(gè)報(bào)錯(cuò)的解釋是導(dǎo)入的包v4和recyclerview.jar不兼容，需要導(dǎo)入<sdk>\extras\android\support統(tǒng)一路徑下的v4包和recyclerview。

發(fā)現(xiàn)是因?yàn)镽ecyclerView控件所依賴的android-support-v4包版本不一致造成的，即項(xiàng)目本身使用了一個(gè)appcompat的依賴（appcompat中包含了android-support-v4.jar），而這個(gè)support-v4和RecyclerView依賴的support-v4不是一個(gè)版本（從RecyclerView的源碼中可以看到其確實(shí)使用了不少的support-v4工具類）
但我的情況仍然不起效，判斷依然是包不兼容導(dǎo)致的。但不知為何導(dǎo)入同一個(gè)版本重新下載的包不起效。

在stackflow上找到另一種解決方案

  • Go to C:\Users\Hk-PC\Desktop\eclipse\adt-bundle-windows-x86->20140702\sdk\extras\android\m2repository\com\android\support\recyclerview-v7\22.1.1
  • Open recyclerview-v7-22.1.1.aar file with Winrar
  • There is a jar file named classes.jar. Copy that to your project libs folder.
  • Right click classes.jar, add to build path.
    來(lái)源： http://stackoverflow.com/questions/29998850/recyclerview-class-not-found-in-eclipse

不要問(wèn)我為何這種方式就可以了，而且這個(gè)方法復(fù)用性很低，就是說(shuō)我把包刪掉再按這個(gè)步驟來(lái)估計(jì)又會(huì)失效。網(wǎng)上資料幾乎沒(méi)有，用AS代替吧
