动态更改ListView项目大小kotlin

class CustomAdapter(private val context: Context, private val itemList: List<String>) : BaseAdapter() {

    override fun getCount(): Int {
        return itemList.size
    }

    override fun getItem(position: Int): Any {
        return itemList[position]
    }

    override fun getItemId(position: Int): Long {
        return position.toLong()
    }

        var view = convertView
        val viewHolder: ViewHolder

        if (view == null) {
            view = LayoutInflater.from(context).inflate(R.layout.list_item, parent, false)
            viewHolder = ViewHolder(view)
            view.tag = viewHolder
        } else {
            viewHolder = view.tag as ViewHolder
        }

        // 设置项目的大小
        val layoutParams = view.layoutParams
        layoutParams.width = 200 // 设置宽度为200像素
        layoutParams.height = 100 // 设置高度为100像素
        view.layoutParams = layoutParams

        // 设置其他项目内容
        viewHolder.itemTextView.text = itemList[position]

        return view
    }

    private class ViewHolder(view: View) {

}

val listView: ListView = findViewById(R.id.listView)
val itemList = listOf("Item 1", "Item 2", "Item 3") // 假设有一个项目列表
val adapter = CustomAdapter(this, itemList)
listView.adapter = adapter
