I try to do AlertDialog with ListView (adapter), and I get the Alert Dialog but I dont get the ListView, so my code is:

    public void namesDialog(View view){
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    LayoutInflater inflater = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View v = inflater.inflate(R.layout.list_view_names_dialog, null);
    builder.setTitle("Names:");
    builder.setView(v);
    final ListAdapterDetailsNames adapter = new ListAdapterDetailsNames(this, mNames.getNames());
    mListViewTextNames.setAdapter(adapter);
    AlertDialog dialog = builder.create();
    dialog.show();

}

What I should do to get the listView in the AlertDialog?

Thanks a lot for you help :)

  • Your list view is empty. So then you see no items. – greenapps Feb 12 '18 at 15:37
  • What is your intention with mListViewTextNames? If it is a ListView then why not use that one? – greenapps Feb 12 '18 at 15:37
  • @greenapps the mListViewTextNames this is the ListView..what I should do to fix it? – A666 Feb 12 '18 at 15:41
  • That i already told you: builder.setView(mListViewTextNames); – greenapps Feb 12 '18 at 15:55

What is mListViewTextNames? You’re setting the adapter to a view that seems to exist even before you inflate R.layout.list_view_names_dialog... you almost certainly need to findViewById() within the inflated view to get the correct ListView to set the adapter on.

  • mListViewTextName is a ListView, so I try to get the ListView from layout: list_view_names_dialog – A666 Feb 12 '18 at 15:47
  • @Ei123456 do you see, though, that in the code you posted there's no reference to finding mListViewTextNames? You take the trouble to call inflate() on R.layout.list_view_names_dialog, and this is your dialog's body view, but since you're not actually obtaining a reference to a ListView from that body view, you must be setting the adapter on some other ListView that's not in the dialog. – Ben P.

  • ok, now I am understand this and it's work fine!, thanks @Ben P. – A666 Feb 12 '18 at 20:31
