android - How to prevent the RecyclerView from resorting while notifyDataSetChanged -

-

i use staggeredgridlayoutmanager recyclerview layout manager. when try load next page data , call notifydatasetchanged method update data, while scroll recyclerview, notice resort item.

i don't need resort it, how can prevent resorting. , wonder why resort.

thx!

@ershani gave valuable insight problem , adding more on top of it.

use notifydatasetchanged() last resort when using recycler view. notifydatasetchanged() following , quoting doc

this event not specify data set has changed, forcing observers assume existing items , structure may no longer valid. layoutmanagers forced rebind , relayout visible views.

if writing adapter more efficient use more specific change events if can. rely on notifydatasetchanged() last resort.

so in case if call notifydatasetchanged(), bound , visible layouts rebound pointless , ineffective.

you use notifyitemrangeinserted() after loading page. more effective , retains default animations provided recyclerview on data set changes.

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course,
