Разбираюсь с ListView. Список выводится, но при клике ничего не происходит.
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
var listView = findViewById<ListView>(R.id.lv_list)
listView.adapter = MyAdapter(this)
listView.setOnItemClickListener {parent, view, position, id ->
Toast.makeText(this@MainActivity, "zzz", Toast.LENGTH_SHORT).show()
Log.e("AAA", "zzz")
}
}
}
class MyAdapter(private var context: Context): BaseAdapter() {
private val inflater: LayoutInflater =
context.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
override fun getCount(): Int {
return 10
}
override fun getItem(position: Int): Any {
return "Item ${position + 1}"
}
override fun getItemId(position: Int): Long {
return position.toLong()
}
override fun getView(position: Int, convertView: View?, parent: ViewGroup): View {
val rowView = inflater.inflate(R.layout.list_item, parent, false)
var tv_text = rowView.findViewById<TextView>(R.id.tv_text)
tv_text.text = "Item ${position + 1}"
return rowView
}
}
