android object to hashmap (on listview)

i am trying to listen to click on listview which each row is hashmap: 

lvItem = (ListView)getView().findViewById(R.id.listWork); 
ArrayList<HashMap<String, String>> mylistData = new ArrayList<HashMap<String, String>>();
HashMap<String, String> map = new HashMap<String, String>(); 
int[] columnID = new int[] {R.id.tvPK, R.id.tvText }; 
map.put("PK", "1"); 
map.put("ITEM", "2"); 
mylistData.add(map);

SimpleAdapter arrayadapter = new SimpleAdapter(getActivity(), mylistData, R.layout.row_hidden_id, new String[] {"PK", "ITEM"}, columnID);
lvItem.setAdapter(arrayadapter);
lvItem.setTextFilterEnabled(true);

lvItem.setOnItemClickListener(new OnItemClickListener() {  
 @Override  
 public void onItemClick(AdapterView<?> a, View v, int p, long id) {   
  Object o = lvItem.getItemAtPosition(p);   
  ErrorMsg("ID:" + o.toString());
 } });

i am getting something like "{ITEX=2, PK=1}"
i need to cast the object (o) as hashmap and get only the pk...

any idea?

Thanks!

Try:

lvItem.setOnItemClickListener(new OnItemClickListener() {  
    @Override  
    public void onItemClick(AdapterView<?> a, View v, int p, long id) {   
        HashMap<String,String> map = (HashMap) lvItem.getItemAtPosition(p);   
        ErrorMsg("ID:" + map.get("PK"));
     } 
});
