android - FirebaseRecyclerAdapter not updating data automatically -


i using firebaserecycleradapter comes firebaseandroid-ui library , assume when data change on firebase automatically refresh , update recyclerview.

my code simple:

firebase firebasepicturesref = new firebase(firebase_url);  madapter = new firebaserecycleradapter<image, imageviewholder>(         image.class, r.layout.pictures_grid_item,         imageviewholder.class, firebasepicturesref) {      @override     protected void populateviewholder(imageviewholder viewholder, image model, int position) {         super.populateviewholder(viewholder, model, position);         glide.with(getactivity()).load(model.getthumbnailurl()).into(viewholder.mimageview);     } };

i have tried manually refresh adapter using notifydatasetchanged in the ondatachange method:

firebasepicturesref.addvalueeventlistener(new valueeventlistener() {     @override     public void ondatachange(datasnapshot datasnapshot) {         if (madapter != null)             madapter.notifydatasetchanged();     }      @override     public void oncancelled(firebaseerror firebaseerror) {      } });

am doing wrong? fix?

i found problem, calling madapter.cleanup(); in onstop() of fragment. removing fixed problem.

instead of doing cleanup in onstop(); should called in ondestroy()

as suggested frank:

in general should call cleanup() in "opposite" method create adapter. oncreate()<->ondestroy(), onstart()<->onstop(), onpause()<->onresume()

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -
