Should the other items be shown when a new sort query is entered? What is this new query, is it only a Boolean or is it string based sort? – Haroun Hajem Mar 26 '19 at 17:42

Add the method inside the adaptre, hope it helps:
public void sortItem() {
ArrayList<Item> items = new ArrayList<>();
Item top =null ;
for(Item item : data){
if(!item.isTop){
items.add(item);
}else{
top = item;
}
}
if(top!=null){
items.add(0, top);
}
data.clear();
data.addAll(items);
adapter.notifyDataSetChanged();
}
class Item{
public Boolean isTop;
}
if You want get sorted list right away You can sort the list and submit yo recycler view adaper inside the activity:
ArrayList<Item> items = new ArrayList<>();
Item top =null ;
for(Item item : data){
if(!item.isTop){
items.add(item);
}else{
top = item;
}
}
if(top!=null){
items.add(0, top);
}
yourAdapter.submitList(items)
