在我得到以下错误后,我将findViewById转换为kotlin合成。但是一切都一样。我之前有确切的问题。在这里,我通过在onCreateView()之后访问id(即onViewCreated())来解决它。在这里我不知道如何解决该问题?谢谢。
The resource R.id.item_help_description appears to be unused [UnusedIds]
这是我的代码
internal class HelpAdapter(titleDescriptionMap: Map<String, String>) :
RecyclerView.Adapter<HelpAdapter.Item>() {
private var titles: Array<String> = titleDescriptionMap.keys.toTypedArray()
private var descriptions: Array<String> = titleDescriptionMap.values.toTypedArray()
override fun onCreateViewHolder(
parent: ViewGroup,
viewType: Int
): Item = Item(
LayoutInflater.from(parent.context)
.inflate(R.layout.item_help, parent, false)
)
override fun onBindViewHolder(
holder: Item,
position: Int
) {
holder.itemView.item_help_description.text = descriptions[position]
holder.itemView.item_help_title.text = titles[position]
}
override fun getItemCount(): Int = titles.size
internal inner class Item(itemView: View) :
RecyclerView.ViewHolder(itemView) {
init {
itemView.item_help_title.setOnClickListener { toggleDescriptionVisibility() }
itemView.item_help_toggle_expand.setOnClickListener { toggleDescriptionVisibility() }
}
@SuppressWarnings("MagicNumber")
fun toggleDescriptionVisibility() {
if (itemView.item_help_description.visibility == View.GONE) {
ObjectAnimator.ofFloat(itemView.item_help_toggle_expand, "rotation", 0f, 180f).start()
itemView.item_help_description.expand()
} else {
ObjectAnimator.ofFloat(itemView.item_help_toggle_expand, "rotation", 180f, 360f).start()
itemView.item_help_description.collapse()
}
}
}
}
