I have the following code:
class BookListActivity : AppCompatActivity()
{
var array = arrayOf("Item 1", "Item 2", "Item 3", "Item 4", "Item 5", "Item 6", "Item 7", "Item 8", "Item 9", "Item 10", "Item 11")
override fun onCreate(savedInstanceState: Bundle?)
{
super.onCreate(savedInstanceState)
setContentView(R.layout.book_list)
val adapter = ArrayAdapter(this, R.layout.book_list_item, R.id.book_title, array)
val listView : ListView = findViewById(R.id.book_list)
listView.adapter = adapter
}
}
I need to add a click listener for each element on the listView.
I've tried the following but doesn't work:
listView.setOnItemClickListener
{
val intent = Intent(this, BookDetailActivity::class.java)
startActivity(intent)
}
Also I need to know what ListView element I've clicked. How can I do this?
You have to handle all the parameters for AdapterView.OnItemClickListener
Your listener should look like this:
listView.setOnItemClickListener { parent, view, position, id ->
val element = adapter.getItemAtPosition(position) // The item that was clicked
val intent = Intent(this, BookDetailActivity::class.java)
startActivity(intent)
}
Try this solution for listview item click listener.
listView.setOnItemClickListener = AdapterView.OnItemClickListener {parent,view, position, id ->
// Get the selected item text from ListView
val selectedItem = parent.getItemAtPosition(position) as String
val intent = Intent(this, BookDetailActivity::class.java)
startActivity(intent)
}
