Here is a usable copy of the code:

spinner2.setOnItemSelectedListener(new CustomOnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> adapterView, View view, int position, long id) {
        ArrayList<HashMap<String, String>> arrList = new ArrayList<HashMap<String,String>>();
        // for each key in the hashMap at this position..
        for (String key : arrList.get(position).get("SectionID"))
        {
        }
    }                                      

    @Override
    public void onNothingSelected(AdapterView<?> adapter) {}
});

You must do this one level at a time. First fetch each HashMap from your ArrayList, then ask for your specific key:

for (HashMap<String, String> map : arrList) {
    String value = map.get("SectionID");
    // Do something
}

However if you just initialized arrList there won't be anything in it...
