android - E/RecyclerView: No adapter attached; skipping layout (Using FRAGMENTS) -


i modified code according answers found similar questions none of them worked. using tabfragments , recyclerviews. console displays error "e/recyclerview: no adapter attached; skipping layout" 4 times.

(when modifying gave me error "java.lang.nullpointerexception: attempt invoke virtual method 'void android.support.v7.widget.recyclerview.setlayoutmanager(android.support.v7.widget.recyclerview$layoutmanager)' on null object reference", maybe correlated).

adapter

public class ingredientadapter extends recyclerview.adapter<ingredientadapter.viewholder>{  public arraylist<ingredient> dataset = new arraylist<>(); public context ctx;   public static class viewholder extends recyclerview.viewholder {      public view view;      public viewholder(view itemview) {         super(itemview);         view = itemview;     } }  public ingredientadapter(context ctx){     super();     this.ctx = ctx; }  @override public ingredientadapter.viewholder oncreateviewholder(viewgroup parent, int viewtype) {         view v = layoutinflater.from(parent.getcontext()).inflate(r.layout.ingredient_row, parent, false);          viewholder vh = null;         vh = new viewholder(v);              return vh; }  public void setdataset(arraylist<ingredient> dataset) {     this.dataset.clear();     this.dataset = dataset;     this.notifyitemrangeinserted(0, this.dataset.size() - 1); }  @override public void onbindviewholder(ingredientadapter.viewholder holder, int position) {     imageview image = (imageview) holder.view.findviewbyid(r.id.ingredient_image);     image.setimagebitmap(dataset.get(position).getimage());     textview name = (textview)holder.view.findviewbyid(r.id.ingredient_name);     name.settext(dataset.get(position).getname()); }  @override public int getitemcount() {     return dataset.size(); }

}

tabfragment

public class tabfragmentingredients extends fragment { @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {      view rootview = inflater.inflate(r.layout.recyclerview_list, container, false);     rootview.settag("recyclerviewfragment");     recyclerview recycler = (recyclerview) rootview.findviewbyid(r.id.recycler_view);       final linearlayoutmanager layoutmanager = new linearlayoutmanager(this.getactivity());     layoutmanager.setorientation(linearlayoutmanager.vertical);     recycler.setlayoutmanager(layoutmanager);      arraylist ingredients = new arraylist<ingredient>();     ingredients.add(new ingredient("carrot", bitmapfactory.decoderesource(this.getcontext().getresources(),r.drawable.carrot)));     system.out.println(ingredients.size());     ingredientadapter adapter = new ingredientadapter(this.getcontext());     adapter.setdataset(ingredients);     recycler.setadapter(adapter);      return inflater.inflate(r.layout.recyclerview_list, container, false); }

}

change return inflater.inflate(r.layout.recyclerview_list, container, false); return rootview;

i have entity inherits other. on other hand, i'm using lombok project reduce boilerplate code, put @data annotation. annotation @data inheritance produces next warning: generating equals/hashcode implementation without call superclass, though class not extend java.lang.object. if intentional, add '@equalsandhashcode(callsuper=false)' type. is advisable add annotation @equalsandhashcode (callsuper = true) or @equalsandhashcode (callsuper = false) ? if not added, 1 callsuper=false or callsuper=true ? the default value false . 1 if don't specify , ignore warning. yes, recommended add @equalsandhashcode annotation on @data annotated classes extend else object. cannot tell if need true or false , depends on class hierarchy, , need examined on case-by-case basis. however, project or package, can configure in lombok.config call super methods if not direct subclass of object. lombok.equalsandhashcode.callsuper = call for configuration system ...
