onItemSelectedListener only triggered if selection actually change?

Question

I use setOnItemSelectedListener on a spinner. The listener is triggered if I change the selection but not if I select the same item that is already selected. I need to be nofified even if the user select the same item that is already selected. I tought about using setOnItemClickListener but it is not supported by the Spinner.

Any hints ?

TIA

If you're still looking for a solution to this question, Regis, it may be worth having a look at a related question I asked a while ago, which has several answers with good ideas on how to work around this issue.

@RegisSt-Gelais: I was wondering why I'd got an accept and a downvote within a few seconds of each other... funnily enough, it earned me a gold badge for having 10 zero-score accepted answers :-) – Amos M. Carpenter Apr 19 '19 at 01:03

Did you tried to override onNothingSelected()? in onNS() you implement to do/get/whatever item that is selected by "default". I hope you get my idea.

spin.setOnItemSelectedListener(new OnItemSelectedListener(){

@Override
    public void onItemSelected(AdapterView<?> arg0, View arg1,int arg2, long arg3) {
                        // Some operation with other selection
                            }
    @Override
      public void onNothingSelected(AdapterView<?> arg0) {
    //operation with that item that onItemSelected() did not triggered. I mean, let's say you have 3 items on the spinner: A,B,C. Initially what we see its the A item and on this item this method will apply.
    }});

I did try onItemSelected but not onNothingSelected. The doc is not realy clear on what it does. I will give it a try next monday and get back to you. – Regis St-Gelais Aug 13 '11 at 08:26
onNothingSelected does not do what I need. In fact I was not able to find how to trigger it. – Regis St-Gelais Aug 14 '11 at 10:09
Did you override it? It must be overrided inside the `new OnItemSelectedListener()`... – Nikola Despotoski Aug 14 '11 at 11:03

Yes. onItemSelected is triggered when a new selection is made but onNothingSelected is never triggered. – Regis St-Gelais Aug 15 '11 at 20:42
The doc says onNothingSelected: Callback method to be invoked when the selection disappears from this view. – Regis St-Gelais Aug 15 '11 at 20:43
