Android Spinner: Get the selected item change event

Question

How can you set the event listener for a Spinner when the selected item changes?

Basically what I am trying to do is something similar to this:

spinn

You can avoid the OnItemSelectedListener() being called with a simple check: Store the current selection index in an integer variable and check within the onItemSelected(..) before doing anything.

E.g:

Spinner spnLocale;

spnLocale = (Spinner)findViewById(R.id.spnLocale);

int iCurrentSelection = spnLocale.getSelectedItemPosition();

spnLocale.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    public void onItemSelected(AdapterView adapterView, View view, int i, long l) { 
    if (iCurrentSelection != i){
            // Your code here
    }
    iCurrentSelection = i;
    } 

    public void onNothingSelected(AdapterView adapterView) {
        return;
    } 
}); 

Of cause the iCurrentSelection should be in object scope for this to work!
