Question

I am working with Spinner, cursors and adapters.

I want to setup a click listener for the spinner so that once a user selects an item from the spinner it gets the current selected item and then carrys out some other tasks ( all this extra code is fine, its just 1 problem I am having)…. It kind of works, however, once I declare the setOnItemSelectedListener callback, since the cursor has already been populated, the event is fired as soon as the app launches.

I guess I need a way to define the cursor without selecting an initial item so that the event doesnt fire (since an item will not be selected). Or is there another better way to achieve this?

Basically, as it stands, once the app loads the setOnItemSelectedListener function is firing because the cursor is being populated ( i think). Moreover, ignoreing the fact that the event is firing too soon, if I then select the -same- item in the spinner, it doesnt fire the event sincethe item didnt change. SHould I be using a different callback instead of setonitemslectedlistener? Here is the code I have so far.

            c = db.getallrecents();
    startManagingCursor(c);

    busnumspinner = (Spinner) findViewById(R.id.Spinner01);

        SimpleCursorAdapter spinneradapter = new SimpleCursorAdapter(this,
                R.layout.lvlayout, c, spincol, spinto);

    busnumspinner.setAdapter(spinneradapter);


    busnumspinner.setOnItemSelectedListener(new OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
            String spinnerString = null;
            Cursor cc = (Cursor)(busnumspinner.getSelectedItem());
            if (cc != null) {
                spinnerString = cc.getString(
                    cc.getColumnIndex("busnum"));
                text = spinnerString;
            }

            showDialog(DATE_DIALOG_ID);

        }

        @Override
        public void onNothingSelected(AdapterView<?> parentView) {
            // your code here
        }
    });

This has already been discussed in this question. Look there, though it has a similar answer like the one given by blindstuff.

EDIT:

If the onItemSelectedListener is not firing when you need it, then you probably need a onClickListener in eachtext item of the droplist and get in there the current position of the selected item of the spinner. The problem is that as it is said here spinner don’t support this event, but maybe you can get it by doing something similar to the explained in this stackoverflow question. I haven’t tried it so I’m not sure it will work.
