Sorting Listview in Android

Collections.sort(list, comparator);
ActAdapter adp = new ActAdapter(getParent(), list);
lv.setAdapter(adp);
adp.notifyDataSetChanged();

Change Order of map1 and map2 as per your requirement


Comparator<HashMap<String, String>> comparator = new Comparator<HashMap<String, String>>() {
    @Override
    public int compare(HashMap<String, String> map1, HashMap<String, String> map2) {
        return map2.get(CREATED).compareTo(map1.get(CREATED));
    }
};
