How to sort ArrayList while implementing Parcelable

Question

I am trying to sort the category arraylist with Collections.sort method but have no luck with it.

Here is my code:

public class Categories i         


        

Answer 1

Collections.sort(yourListHere,new Comparator<Categories>() {
            @Override
            public int compare(Categories lhs, Categories rhs) {
                //your sort logic here
                return 0;
            }
});

Hope this helps.

Answer 2

You can also use custom comparator:

public class CategoriesComparator implements Comparator<Category> {
    @Override
    public int compare(Category category1, Category category2) {
        return category1.getSomeProperty().compareTo(category2.getSomeProperty());
    }
}

When you want to compare call this:

Collections.sort(yourListCategories, new CategoriesComparator());

Hope it helps!
