像標題一樣，我無法獲得正確的專案資料，現在想象我的主要片段上有 2 個回收器視圖串列，一個回收器視圖是垂直的，另一個是水平的。如果我只使用一個回收器，一切正常。但是當我添加另一個時，它會隨機打開專案，但隨機資料打開只會隨機兩個回收站的位置。就像我的第一個回收者有 [a,b,c,d] ，其他回收者有 [e,f,g,h]。當我單擊第一個回收器的第一項時，它轉到顯示細節的另一個片段，它的開頭 e 而不是 a，如果我回去重試它，它再次打開 e，重試和它的 a !! 所以它隨機打開，為什么會發生這種情況為什么我不能打開正確的資料？我將 Log.d 放在我的配接器上，當我單擊回收器專案時，配接器日志顯示您單擊了“a”，但我的詳細資訊片段顯示了“e”的資料。我做錯了什么？這是我的代碼：（我有很多代碼，所以我分享我們需要的）

就像我說的，如果我洗掉我的一個回收器視圖它的作業完美但是如果我在同一個片段上使用兩個回收器我得到錯誤的資料。日志說我打開了正確的資料，但事實并非如此。如果你需要我的其他代碼來解決問題，請說出來我有很多螢屏不知道我需要分享哪一個來解決它。
