android scroll - Check if items are completely visible in the RecyclerView -


i'm trying check if specific items visible in recyclerview; couldn't implement that. please me determine if items visible in recyclerview.

mrecylerview.addonscrolllistener(new recyclerview.onscrolllistener() {     @override     public void onscrolled(recyclerview recyclerview, int dx, int dy) {         super.onscrolled(recyclerview, dx, dy);         linearlayout ll = (linearlayout) recyclerview.findchildviewunder(dx, dy);         if (ll != null) {             texturevideoview tvv = (texturevideoview) ll.findviewbyid(r.id.croptextureview);         }     } });

i want check if tvv view visible within mrecyclerview view.

you make logic using layoutmanager api last visible item position in recyclerview onscrolled method:

((linearlayoutmanager) vyourrecycler.getlayoutmanager()).findlastcompletelyvisibleitemposition();

from documentation: returns adapter position of last visible view. position not include adapter changes dispatched after last layout pass.

try use , notify recyclerview adapter refresh.

note: don't know why you're using findviewbyid in onscrolled method, work should implemented in recyclerview viewholder performance

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
