java - Cursor Adapter behaving strangely (Info in each item is being updated as I scroll, and I can see it being updated) -
okay, not know better way of explaining in words uploaded video, can see going on...
a little background app.. app takes info firebase , stores in sq lite. cursor adapter uses info in sq lite, show items in listview, inside bottom sheet (android design support library)
here cursor adapter code:
public class eventlistcursoradapter extends cursoradapter { private layoutinflater cursorinflater; calculations calculations = new calculations(); gson gson = new gson(); context appcontext; databasehelper dbhelper; context mcontext; string[] whereclause; intent mainactivityintent; public eventlistcursoradapter(context context, cursor c, int flags) { super(context, c, flags); cursorinflater = (layoutinflater) context.getsystemservice(context.layout_inflater_service); appcontext = context.getapplicationcontext(); mcontext = context; notifydatasetchanged(); } @override public view newview(context context, cursor cursor, viewgroup parent) { return cursorinflater.inflate(r.layout.card_view, parent, false);
