Question

I got a custom listview which contains info about tv shows, ie. show title, last episode, last episode date, next episode, next episode date an so on.

Now I want to sort the listview ie. by last episode date. The shows are stored in an Arraylist, and the date is stored as a string in the format MMM/dd/yyyy.

Sort by title works with follow code:

    public void sortByTitle() {
        Comparator<Show> comperator = new Comparator<Show>() {
            @Override
            public int compare(Show object1, Show object2) {
                return object1.getTitle().compareToIgnoreCase(
                        object2.getTitle());
            }
        };
        Collections.sort(dataFromDB, comperator);
        lv1.setAdapter(new CustomListViewAdapter(this, dataFromDB));
    }

Anyone who can help?

Answer 1

Same as you are sorting on the basis of title,can be done with dates also.
Example:

 // sort by date
    public int compareTo(NewsDetails another) 
    {
        if (another == null) return 1;
        // sort descending, most recent first
        return another.date.compareTo(date);
    }
