Kotlin - Copy clicked items of a ListView to clipboard

Question

I have to copy clicked items of a ListView to clipboard manager using Kotlin.

I've tried

listView.setOnItemClickListener { parent, view, position, id ->
            val item = listView.selectedItem as String?
            myClip = ClipData.newPlainText("text", item)
            myClipboard?.primaryClip = myClip }

But it says:

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.ListView.setOnItemClickListener(android.widget.AdapterView$OnItemClickListener)' on a null object reference

For my ListView I used

var values = ArrayList<String>()
val adapter = ArrayAdapter(this, R.layout.listview_text_color, values)
listView?.adapter = adapter
adapter.notifyDataSetChanged()

Answer 1

SOLUTION

Instead of using a listView layout, I used the alertDialog.setAdapter(). Here's the code

     alertDialogList.setAdapter(adapter, DialogInterface.OnClickListener { _, which ->
            val item = adapter.getItem(which) //this is my code to copy clicked items on clipboard
            myClip = ClipData.newPlainText("text", item)
            myClipboard?.primaryClip = myClip
})
