Question

I have a customlist view with an ImageView and a textview. I am retrieving that list view by this method:

private List<Currency> getModel() {
        List<Currency> list = new ArrayList<Currency>();
        for (int i = 0; i < countryCode.length; i++) {

            list.add(get(countryCode[i], flag[i]));
        }


        return list;
    } 

this method returns a list of an image and a textview in a particular list item, and I am setting this in a adapter to show it in a listview. But how can I sort this list by alphabetically comparing with the text of that text view in the list? I have tried this

Collections.sort(list, new Comparator<String>() {
        @Override
        public int compare(String s1, String s2) {
            return s1.compareToIgnoreCase(s2);
        }
    });

but this method only works for string types list, but my list is not in string type? What to do?

Answer 1

Try to compare in this way

Collections.sort(list, new Comparator<Currency>() {
        @Override
        public int compare(Currency c1, Currency c2) {
            return c1.getCurrencyName().compareToIgnoreCase(c2.getCurrencyName());
        }
    })
