检查这个代码

public class ListViewActivity() : AppCompatActivity() { override fun onCreate(savedState: Bundle?) { super.onCreate(savedState) setContentView(R.layout.activity_list_view) val lv = findViewById(R.id.list) as ListView lv.adapter = ListExampleAdapter(this) } private class ListExampleAdapter(context: Context) : BaseAdapter() { internal var sList = arrayOf("Sunday", "Monday") private val mInflator: LayoutInflater init { this.mInflator = LayoutInflater.from(context) } override fun getCount(): Int { return sList.size } override fun getItem(position: Int): Any { return sList[position] } override fun getItemId(position: Int): Long { return position.toLong() } override fun getView(position: Int, convertView: View?, parent: ViewGroup): View? { val view: View? val vh: ListRowHolder if (convertView == null) { view = this.mInflator.inflate(R.layout.list_row, parent, false) vh = ListRowHolder(view) view.tag = vh } else { view = convertView vh = view.tag as ListRowHolder } vh.label.text = sList[position] return view } } private class ListRowHolder(row: View?) { public val label: TextView init { this.label = row?.findViewById(R.id.label) as TextView } }
