我有一个home片段,我想让它转到另一个显示其“详细信息”的片段,该片段将所单击的recyclerview项的数据传递给该“详细信息”片段。
当我点击文章,它会移动到详细文章,通过数据。
至于代码,下面是适配器:
class ArticleAdapter(private val articleList: ArrayList<Article>) :
RecyclerView.Adapter<ArticleAdapter.MyViewHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder {
val binding = ItemArticleBinding.inflate(LayoutInflater.from(parent.context), parent, false)
return MyViewHolder(binding)
}
override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
val data = articleList[position]
holder.bind(data)
}
class MyViewHolder(private val binding: ItemArticleBinding) :
RecyclerView.ViewHolder(binding.root) {
fun bind(data: Article) {
Glide.with(binding.root.context)
.load(data.img)
.into(binding.articleImage)
binding.articleTitle.text = data.title
binding.root.setOnClickListener {
val article = Article(
data.title,
data.img,
data.content
)
}
}
}
override fun getItemCount(): Int {
return articleList.size
}
}
这是我的详细信息片段
class DetailArticleFragment : Fragment() {
private var _binding: FragmentDetailArticleBinding? = null
private val binding get() = _binding!!
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View {
_binding = FragmentDetailArticleBinding.inflate(inflater, container, false)
return binding.root
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
val intent = Intent(binding.root.context, DetailArticleFragment::class.java)
val article = intent.getParcelableExtra<Article>(DETAIL_ARTICLE) as Article
Glide.with(this)
.load(article.img)
.into(_binding!!.articleImage)
_binding!!.articleTitle.text = article.title
_binding!!.articleDescription.text = article.content
}
override fun onDestroyView() {
super.onDestroyView()
_binding = null
}
companion object {
const val DETAIL_ARTICLE = "detail_article"
}
}

您需要将click listener接口传递给适配器,例如:
并使用RecyclerView在您的主页片段中初始化文章单击:
