在groupie adapter recyclerview android中显示所选项目？

如何解决在groupie adapter recyclerview android中显示所选项目？

我使用 groupie 作为我的 recyclerview 的适配器。 [Groupie Adapter][1]

我有一个水平回收器视图，我使用了可绑定的项目视图。

class WidgetCarousel(private val adapter: GroupieAdapter) : BindableItem<ItemCarouselBinding>() {

override fun initializeViewBinding(view: View): ItemCarouselBinding =
    ItemCarouselBinding.bind(view)

override fun createViewHolder(itemView: View): GroupieViewHolder<ItemCarouselBinding> =
    super.createViewHolder(itemView).also {
        it.binding.recyclerView.apply {
            layoutManager =
                linearlayoutmanager(this.context,linearlayoutmanager.HORIZONTAL,false)
        }
    }

override fun bind(viewBinding: ItemCarouselBinding,position: Int) {
    viewBinding.recyclerView.adapter = adapter
}

override fun getLayout(): Int = R.layout.item_carousel

}

这是我用于水平回收视图的项目

class WidgetStoryItem(val widgetData: WidgetData?) :
BindableItem<ItemStoryBinding?>() {
var selectedWidgetId: String? = null
override fun getLayout(): Int = R.layout.item_story

override fun initializeViewBinding(view: View): ItemStoryBinding =
    ItemStoryBinding.bind(view)

override fun bind(viewBinding: ItemStoryBinding,position: Int) {
    viewBinding.storyTitle.text = widgetData?.body?.title?.replace(" ","\n")
    viewBinding.storyImg.load(widgetData?.body?.iconUrl)
    selectedWidgetId?.let {
        if (it == widgetData?.id)
            viewBinding.storyImgBg.background =
                ContextCompat.getDrawable(
                    viewBinding.storyImgBg.context,R.drawable.bg_selected_story_oval_blue
                )
        else
            viewBinding.storyImgBg.setBackgroundResource(0)
    }

}
}

我使用它如下。我有一个组项目，我将它们添加为

var storyAdapter = GroupieAdapter()
storyAdapter.addAll(storyGroup)
val widgetCarousel: WidgetCarousel = WidgetCarousel(storyAdapter)
groupAdapter.add(0,widgetCarousel)

点击的项目是

private val onItemClickListener = OnItemClickListener { item,_ ->
    if (item is WidgetStoryItem) {
        item.widgetData?.let {
            item.selectedWidgetId=it.id
            storyAdapter.notifyDataSetChanged()
        }
    }

我想在用户单击它时显示用户选择的视图，并将其他视图保持为未选择状态。 对我来说，选择发生了，但它无法从其他项目视图中删除选择。 有什么建议么？ [1]：https://github.com/lisawray/groupie
