Le remplissage de Toupie à l'aide de ArrayList dans Android

J'ai une activité dans laquelle je parse un fichier XML et remplir une Toupie à l'aide de l'analyse de données.

J'en ai fini avec l'analyse du XML. C'est la méthode:

void parse_ExamList()
                    {

                        ArrayList<HashMap<String, String>> menuItems = new ArrayList<HashMap<String, String>>();

                        XMLParser parser = new XMLParser();
                        //String xml = parser.getXmlFromUrl(URL); //getting XML
                        Document doc = parser.getDomElement(xmlContent); //getting DOM element

                        //count_questions=2;

                        NodeList nl = doc.getElementsByTagName(KEY_EXAMSET);
                        //looping through all item nodes <item>
                        for ( int i = 0; i < nl.getLength();i++) {


//                     while(counter< nl.getLength())
//                     {
                            //creating new HashMap
                            HashMap<String, String> map = new HashMap<String, String>();

                            Element e = (Element) nl.item(i);
                            //adding each child node to HashMap key => value
                            //map.put(KEY_EXAMSET, parser.getValue(e, KEY_EXAMSET));
                            map.put(KEY_SETID, parser.getValue(e, KEY_SETID));
                            map.put(KEY_SETNAME, parser.getValue(e, KEY_SETNAME));
                            //Log.i("Set ID: ", parser.getValue(e, KEY_SETID));
                            //Log.i("Set Name: ", parser.getValue(e, KEY_SETNAME));

                            menuItems.add(map);
                        }


                    }

Si vous remarquez, vous pouvez voir que KEY_SETID et KEY_SETNAME à la liste de tableaux. Je dois remplir la casserole avec le KEY_SETNAME et la KEY_SETID ne sera pas affiché dans le compteur. Mais si l'élément est cliqué puis l'id correspondant au nom doit être acquis dans le but de les envoyer au serveur.

J'ai une méthode pour remplir un spinner, comme ceci:

//add items into exam list spinner dynamically
                    public void addItemsOnExamListSpinner()
                    {
                        List<String> list = new ArrayList<String>();
                        list.add("Speed Test 150(min) PO Set-01");

                        ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,
                        android.R.layout.simple_spinner_item, list);
                        dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
                        exam_list_spinner.setAdapter(dataAdapter);
                    }

Comment dois-je remplir la casserole avec de l'ArrayList qui est obtenu lors de l'analyse du XML?

C'est le fichier de mise en page:

Que dois-je faire pour remplir le compteur de la liste de tableaux retournés par la méthode d'analyse XML?
