我想在 recyclerview 的 Spanned GridLayoutManager 中显示列表数据,但是添加辅助类 Spanned GridLayoutmanager 后,在我的 recycleview 中占用了顶部的大量空间
iam 必须尝试使用其他 SpannedGridlayout 管理器更改 SpannedGridLayoutManager 类,但顶部的空间尚未解决
val manager = SpannedGridLayoutManager(object : SpannedGridLayoutManager.GridSpanLookup{
override fun getSpanInfo(position: Int): SpannedGridLayoutManager.SpanInfo {
// Conditions for 2x2 items
return if (position % 12 == 0 || position % 12 == 7) {
SpannedGridLayoutManager.SpanInfo(2, 2)
} else {
SpannedGridLayoutManager.SpanInfo(1, 1)
}
}
},3/*column*/,1f/*how big is default item*/)
binding.feedHome.setHasFixedSize(false)
binding.feedHome.layoutManager = manager
binding.feedHome.adapter = adapter
这是我的 recycleview 的 xml
<?xml version="1.0" encoding="utf-8"?>

这是我的 recyclerview 项目布局

我希望我错过了 SpannedGridLayoutManager 类中的一些更新或修复错误,但我不知道如何解决它
=======编辑=======
~ 通过在 RecyclerView 之前给予 Linearlayout 解决
~ 不要在项目 RecyclerView 的 Rootlayout 中提供 Padding 或 Margin
