Through the setOnItemSelectedListener:

spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
        // SEU CÓDIGO 
    }

    @Override
    public void onNothingSelected(AdapterView<?> parentView) {
         // SEU CÓDIGO 
    }

});
