Codename one - autocompletetextfield getitem selected - codenameone

Question

I have two problems:
1) First, I want to add a map in AutoCompleteTextField exactlly in DefaultListModel and after I want to add the the listmodel in my autocompletetextField
2) How can I get the text when I select an element in the AutoCompleteTextField?
Form hi = new Form("Auto Complete", new BoxLayout(BoxLayout.Y_AXIS));
AutoCompleteTextField ac = new AutoCompleteTextField("Short", "Shock", "Sholder", "Shrek0", "3asna", "niazra");
ac.setMinimumElementsShownInPopup(5);
//final DefaultListModel<Map<String,Object>> options = new DefaultListModel<>();
final DefaultListModel<String> options = new DefaultListModel<>();
AutoCompleteTextField an = new AutoCompleteTextField(options);
hi.add(an);
ac.addListListener(a -> {
List<Object> ls = new List<>();
System.out.println("i want to display the text selected");
});
hi.add(ac);
hi.show();

Answer 1

When you select an item in the suggestion box of an AutoCompleteTextField the text of this item is copied to the TextField part of the AutoCompleteTextfield, but this occur only after the ListEvent.
In order to have this behavior, prefer using a Selection Listener on the DefaultListModel:
Form hi = new Form("ACTF", new BoxLayout(BoxLayout.Y_AXIS));
DefaultListModel<String> defList = new DefaultListModel<>("Red", "Green", "Blue", "Orange");
AutoCompleteTextField tf1 = new AutoCompleteTextField(defList);
defList.addSelectionListener((oldid, newid)-> Log.p(defList.getItemAt(newid)));
hi.add(tf1);
hi.show();
I don't know why, it occur two times after showing the form, but it works perfectly fine after.
Edit: If you want to display the text on screen, you must use something like this :
Form hi = new Form("ACTF", new BoxLayout(BoxLayout.Y_AXIS));
Label text = new Label("Selected text");
DefaultListModel<String> defList = new DefaultListModel<>("Red", "Green", "Blue", "Orange");
AutoCompleteTextField tf1 = new AutoCompleteTextField(defList);
defList.addSelectionListener((oldid, newid)-> {
text.setText(defList.getItemAt(newid));
hi.revalidate();
});
hi.add(text);
hi.add(tf1);
hi.show();
EDIT 2: Example with a linked map:
Form hi = new Form("ACTF", new BoxLayout(BoxLayout.Y_AXIS));
Map testMap = new HashMap<String, String>();
testMap.put("Red", "Roses are red");
testMap.put("Green", "Grass is green");
testMap.put("Blue", "Sky is blue");
testMap.put("Orange", "Apricots are orange");
Label text = new Label("Selected text");
DefaultListModel<String> defList = new DefaultListModel<>(testMap.keySet());
AutoCompleteTextField tf1 = new AutoCompleteTextField(defList);
defList.addSelectionListener((oldid, newid)-> {
text.setText((String) testMap.get(defList.getItemAt(newid)));
hi.revalidate();
});
hi.add(text);
hi.add(tf1);
hi.show();
