Question

I am retrieving the string data from an element clicked in my listview.

The element has two rows, one named “current” and one named “name”.
in my listItemOnClick(), i am getting the item that was clicked, and then doing toString() on it. what i am getting is something like this:

{current=SOMETHING, name=SOMETHING}

My question is how do i separate these? Here is my onclick code:

    protected void onListItemClick(ListView l, View v, int position, long id) {
    // TODO Auto-generated method stub
    super.onListItemClick(l, v, position, id);
    Object o = this.getListAdapter().getItem(position);
    String current = o.toString();

    ((TextView) findViewById(R.id.check)).setText(current);
}

I want to disply only the current for example. Thanks!

EDIT

My List Variables:

    static final ArrayList<HashMap<String,String>> listItems = 
        new ArrayList<HashMap<String,String>>();;
SimpleAdapter adapter;

Creating the list:

       for(int i=0; i<num_enter; i++){
    final int gi = i;
    adapter=new SimpleAdapter(this, listItems, R.layout.custom_row_view,new String[]{"name", "current"},  new int[] {R.id.text1, R.id.text2});
    setListAdapter(adapter);
    HashMap<String,String> temp = new HashMap<String,String>();
    temp.put("name", name[i]);
    temp.put("current", "Value: " + Integer.toString(current[i]));
    listItems.add(temp);
    adapter.notifyDataSetChanged();
    }

You could do it that way (ugly and prone to future error when / if the format changes) – add error checks in case the string does not have the right format:

String s = "{current=CURRENT, name=NAME}";
s = s.substring(1, s.length() - 1); //removes { and }
String[] items = s.split(",");
String current = items[0].split("=")[1]; //CURRENT
String name = items[1].split("=")[1]; //NAME

Following your edit, it seems that o is a Map so you could also write (much better):

Map<String, String> map = (Map<String, String>) this.getListAdapter().getItem(position);
String current = map.get("current");
String name = map.get("name");
