Kotlin Recycleview，如何为视图制作onItemClick

// 1. 在布局文件中添加RecyclerView控件
<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    />

// 2. 创建数据模型类
data class Item(val name: String)

// 3. 创建RecyclerView的Adapter类
class ItemAdapter(private val items: List<Item>, private val onItemClick: (Item) -> Unit) :
    RecyclerView.Adapter<ItemAdapter.ViewHolder>() {

    // 4. 创建自定义的ViewHolder类
    class ViewHolder(view: View) : RecyclerView.ViewHolder(view) {
        val nameTextView: TextView = view.findViewById(R.id.nameTextView)

        init {
            // 5. 设置点击事件监听器
            view.setOnClickListener {
                onItemClick.invoke(items[adapterPosition])
            }
        }
    }

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

    override fun onBindViewHolder(holder: ViewHolder, position: Int) {
        val item = items[position]
        holder.nameTextView.text = item.name
    }

    override fun getItemCount() = items.size
}

// 6. 在Activity或Fragment中设置RecyclerView
class MainActivity : AppCompatActivity() {

    private lateinit var recyclerView: RecyclerView
    private lateinit var itemAdapter: ItemAdapter

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        recyclerView = findViewById(R.id.recyclerView)

        // 设置LayoutManager
        recyclerView.layoutManager = LinearLayoutManager(this)

        // 创建数据
        val items = listOf(
            Item("Item 1"),
            Item("Item 2"),
            Item("Item 3")
        )

        // 创建Adapter，并设置onItemClick回调
        itemAdapter = ItemAdapter(items) { item ->
            onItemClick(item)
        }

        recyclerView.adapter = itemAdapter
    }

    private fun onItemClick(item: Item) {
        // 处理点击事件
        Toast.makeText(this, "Clicked: ${item.name}", Toast.LENGTH_SHORT).show()
    }
}
