XRecyclerView實現RecyclerView下拉重新整理上來載入 自己做了部分修改，使程式碼更簡潔易用
阿新 • • 發佈：2019-02-12
首先感謝 開源作者
/** * Created by jianghejie on 15/11/26. */的無私奉獻 我是在他的基礎上做的修改
以前一直是用的XListView 可是 測試發現有一個奇奇怪怪的BUG，我們還無法解決。最嚴重的是 XListView 裡面用的新增頭addHeaderView方法在17以前有概率崩潰。後來在同事的專案裡看到PullToZoomListViewEx開原始碼，實現的很好，但是程式碼太難懂，感覺擴充套件性不好。
最後在RecyclerView的強大功能下，還是覺得要用整合RecyclerView的下拉重新整理上拉載入的控制元件才好。
好用整合RecyclerView下拉功能的控制元件都用到了SwipeRefreshLayout佈局，使得下拉樣式很官方，不滿足產品大大的需求。（其實官方多好的）
後來找到了這款開源的控制元件XRecyclerView git地址：https://github.com/jianghejie/XRecyclerView 可以看動畫效果
掩飾不住內心高興的心情，下載下來，發現功能太強的了
但是也有很多不足的地方，不必 很多 選擇重新整理和載入的樣式類。其實一般不需要
主要原理就是把重寫的Adapter 把我們的mHeader和mFooter （如果需要還有 headviews）重組到Adapter 裡面。並且也重寫了監聽。
這個設計簡直就是棒棒噠
還不寫人不知到怎麼引用 RecyclerView 的架包 其實要完成以上的執行需要 RecyclerView V7中的資原始檔 所以是要引用.arr 檔案 並不是.jar
至於他們有什麼區別 請去百度（弄好了那些 可以用在低版本上喲 我的API就是19）
對了 其實對於這個功能的開發 首先要注意有多少狀態 作者對重新整理狀態分了4種 載入 3種。而我自己應為需求只把重新整理和載入都要比作者少一種
廢話不多說了 下面上程式碼 我還自己加了很多註釋喲
