Question

我希望网格布局从上一次加载数据，因为我使用了以下代码

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

它给我这样的错误

当我使用LinearLayoutManager它正在工作但我需要网格视图，请告知应该更好的方法？

Answer 1

它的含义正是如此：setStackFromEnd不受支持。它仅适用于列表，而不适用于网格。

考虑使用反向布局

因此，解决此问题的方法是在setReverseLayout(true)上致电GridLayoutManager。

这意味着您需要撤消列表的整个订单。如果要追加要显示在底部的项目，则必须在开头插入它们。

如何设置setStackFromEnd（true）;在GridLayoutManager for Recyclerview？
