How to sort RecyclerView item in android

Question

I\'m working on a android chatting application. When I called my api it returns me the chat list sorted by a user_id. But what I need to do is serialized by

Answer 1

 Collections.sort(response.body(), new Comparator() {
                        @Override
                        public int compare(All_posts lhs, All_posts rhs) {
                            if(lhs.getId() > rhs.getId()) {
                                return -1;
                            } else {
                                return 1;
                            }
                        }
                    });

• "response.body" is the arraylist I got from json, this is what I pass to the recycler view adapter,

• "All_posts" is the "Model" class, the one which contains only fields;

• And getId is the value I want comparison to take place on it, it's from my model class,

I wrote this before I set my adapter to my recycler view. and after I set my adpater to my recyclerView, I wrote recyclerView.getAdapter().notifyDataSetChanged();
