在使用分页库3.0时，我们如何才能将整个对象列表传递给PagingDataAdapter？

implementation "androidx.paging:paging-runtime-ktx:3.0.0"

class UserAdapter : PagingDataAdapter<User, UserViewHolder>(UserComparator) {
    // ...
}

override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): UserViewHolder {
    val view = LayoutInflater.from(parent.context).inflate(R.layout.item_user, parent, false)
    return UserViewHolder(view)
}

override fun onBindViewHolder(holder: UserViewHolder, position: Int) {
    val user = getItem(position)
    holder.bind(user)
}

class UserViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
    fun bind(user: User?) {
        // 绑定数据到视图
    }
}

val userList: List<User> = // 获取整个对象列表
val pagingData: PagingData<User> = PagingData.from(userList)

val userAdapter = UserAdapter()
userAdapter.submitData(lifecycle, pagingData)
