根据下面的评论，我更改了我的布局。它正在工作，但是当我转到 recyclerview 中的项目底部并尝试向上滚动时，它只会向上滚动到 recyclerview 的开头。我必须再次滚动才能到达标题。

如果您需要精确的 Instagram 设计，请查看此 Sample :
当您单击选项卡按钮时，只需使用隐藏和显示 View ，并为两者放置单独的布局管理器。
private boolean gridClick = false;
case R.id.list_click:
if(listClick) { // Check whether the tab is already clicked or not
Log.e("AlreadyClicked", "Test");
} else {
Log.e("ClickedFirstTime", "Test");
loadPost();
ivGrid.setVisibility(View.GONE); // Hiding grid recyclerview
ivList.setVisibility(View.VISIBLE); // showing list recyclerview
rvGrid.setVisibility(View.GONE); // Make grid recyclerview as gone
recyclerList.setVisibility(View.VISIBLE); // make listview as visible
RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(this); // Use separate layoutmanager for list recyclerview
recyclerList.setLayoutManager(mLayoutManager);
recyclerList.setItemAnimator(new DefaultItemAnimator());
recyclerList.setAdapter(friendsProfileUserPostitemsAdapter);
listClick = true;
}
break;
