I have a recyclerview using listAdaper.this recyclerview has so many Items(this is chat list).
if i edit a particular item of list , DiffUtil compare all of the items of the newlist and old list. it takes long time so updating the list has delay;
is there any way to restrict the Diffutil to compare just particular item?

If you know what that item is, you can trigger the refresh on the list directly. DiffUtil is intended for other purposes. – Sergey M Feb 27 '21 at 13:39

`DiffUtil` will just update the visible changed item (calling necessary "onBindViewHolder()") and with animations. – Sam Chen Feb 27 '21 at 15:34

@fatemehalizadeh exactly. you can update your chat item as soon as a new message received. no need for whole update. – behrad Feb 27 '21 at 19:57
