我的最低SDK版本是16
我使用了<androidx.recyclerview.widget.RecyclerView
这是我的Java代码：
MCC = FirebaseDatabase.getInstance().getReference().child("Troll");
recyclerView = (RecyclerView) findViewById(R.id.TrollID_recyclerView);
recyclerView.setHasFixedSize(true);
layoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(new GridLayoutManager(this, 1));
LoadData(categoryId);

你应该首先将最新的项目存储在recycleadapterList中，然后再将其他项目添加到列表中。因为recycleadapter会根据列表项的位置显示项目。
英文:
you should store latest item first in recycleadapterList then your other items add to list.
because recycleadapter show items like list item position
