我想網格佈局,從去年的,我用下面的代碼如何設置setStackFromEnd(true);在GridLayoutManager for Recyclerview?

GridLayoutManager recyclerViewLayoutManager = new GridLayoutManager(getActivity(), 3); 
//  LinearLayoutManager recyclerViewLayoutManager = new LinearLayoutManager(getActivity()); 
recyclerViewLayoutManager.setStackFromEnd(true); 
lv_explore.setLayoutManager(recyclerViewLayoutManager); 

數據加載它給我的錯誤是這樣

當我使用LinearLayoutManager這是工作,但我需要網格視圖,請告知什麼應該是更好的方法?

這就是它說的:setStackFromEnd不支持。它只適用於列表,而不是網格。

考慮使用反向佈局

所以你解決這個問題的方法是調用setReverseLayout(true)GridLayoutManager

這意味着您將需要反轉您的清單的整個訂單。如果您正在追加意圖顯示在底部的項目,您將不得不在開頭插入它們。
