Android ListView的Kotlin setOnClickListener

我有以下代码：

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    
    }
}

我需要为listView上的每个元素添加一个click侦听器

我尝试了以下方法，但无效：

listView.setOnItemClickListener
{
    val intent = Intent(this, BookDetailActivity::class.java)
    startActivity(intent)
}

---

我还需要知道我点击了什么ListView元素。我如何才能做到这一点？

您必须处理

您的侦听器应如下所示：

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)
}

---

您必须处理的所有参数

您的侦听器应如下所示：

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)
}

---

请为listview项目单击侦听器尝试此解决方案

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)
    }

请为listview项目单击侦听器尝试此解决方案

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)
    }

我宁愿做parent.getItemAtPositionposition我宁愿做parent.getItemAtPositionposition
