i`m trying save , restore states of recyclerview on orientation in fragment changed , kinda works, 1 layout manager only. example: if linearlayoutmanager only, maintains position once rotating , changing staggeredgrid, loads items loses scroll position
if (configuration.landscape(getactivity())) { newslistview.setlayoutmanager(new staggeredgridlayoutmanager(2, staggeredgridlayoutmanager.vertical)); } else { if(getresources().getboolean(r.bool.is_tablet)) { newslistview.setlayoutmanager(new staggeredgridlayoutmanager(2, staggeredgridlayoutmanager.vertical)); } else { newslistview.setlayoutmanager(new linearlayoutmanager(getactivity())); } } this code layout changing on orientation, it`s inside oncreateview , after instance check
if (savedinstancestate != null) { productslistsaved = new arraylist<>(); productslistsaved = (arraylist<hashmap<string,string>>) savedinstancestate.getserializable("newsfeed"); adapter = new recyclerviewadapter(getactivity(), productslistsaved); newslistview.setadapter(adapter); } else { new synchronize.loadallproducts(getactivity()).execute(categorie); } so, possible save&restore&change layout manager @ same time?
thanks in advanced
