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

Question

我希望网格布局从最后加载我使用下面代码的数据

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

java.lang.UnsupportedOperationException: GridLayoutManager does not support stack from end. Consider using reverse layout

当我使用LinearLayoutManager它工作但我需要网格视图,请告知什么应该是更好的方法？

正如它所说：setStackFromEnd不支持。它仅适用于列表，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调用setReverseLayout(true)您的GridLayoutManager.

这意味着您需要颠倒列表的整个顺序。如果您要附加要显示在底部的项目，则必须将它们插入到开头。
