从ListView获取所有项目并转换为字符串Javafx？

Question

I have a ListView in my Netbeans 8.1 Javafx project, and I wish to retrieve all the items from a ListView that have been added to that and have them in a String. I do not just want the selected item in the ListView, I want every item.

Apologies that I have no attempt at code, as I really do not know how to go about this. Thank you in advance for your help and time.

Answer 1

Using the Collectors class (example is just copy and pasted from there).

 // Convert elements to strings and concatenate them, separated by commas
 String joined = listView.getItems().stream()
                       .map(Object::toString)
                       .collect(Collectors.joining(", "));

Answer 2

Well, ListView does have a method called getItems(). You might want to start with that.

Answer 3

By converting from a Observablelist to a List, I was easily able to convert it to a String to suit my needs.

List<String> numbers = listView.getItems();
String listString = String.join(", ", numbers);
