Android Recycler Ver problema en "onBindViewHolder" función "método estático no puede ser llamado de método no estático"

Hussain Mansuri:

Soy nuevo en Android y Java. No soy capaz de llamar a ViewHolder.setCategoryName(name);la onBindViewHolderfunción. Sé que hay probablemente preguntas similares, pero nada ha funcionado para mí todavía. El compilador da error "funciones no estáticos no pueden ser llamados desde un contexto estático", no he utilizado en cualquier lugar de palabras clave estática en mi código.

public class CategoryAdapter extends RecyclerView.Adapter<CategoryAdapter.ViewHolder> {

    private List<CategoryModel> categoryModelList;

    public CategoryAdapter(List<CategoryModel> categoryModelList) {
        this.categoryModelList = categoryModelList;
    }

    @NonNull
    @Override
    public CategoryAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int position) {
        View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.category_item,viewGroup,false);
        return new ViewHolder(view);
    }

    @Override
    public  void onBindViewHolder(@NonNull CategoryAdapter.ViewHolder holder, int position) {
        String icon = categoryModelList.get(position).getCategoryIconLink();
        String name = categoryModelList.get(position).getCategoryName();
        ViewHolder.setCategoryName(name);

    }


    @Override
    public int getItemCount() {
        return categoryModelList.size();
    }


    public class ViewHolder extends  RecyclerView.ViewHolder{

       private ImageView categoryIcon;
       private TextView categoryName;

        public ViewHolder(@NonNull View itemView)  {
              super(itemView);
              categoryIcon = itemView.findViewById(R.id.category_icon);
              categoryName = itemView.findViewById(R.id.category_name);

        }

        private void setCategoryIcon(){

        }
        private void setCategoryName(String name){

            categoryName.setText(name);
        }
    }
}

prueba esto:

public class CategoryAdapter extends RecyclerView.Adapter<CategoryAdapter.ViewHolder> {

    private List<CategoryModel> categoryModelList;

    public CategoryAdapter(List<CategoryModel> categoryModelList) {
        this.categoryModelList = categoryModelList;
    }

    @NonNull
    @Override
    public CategoryAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int position) {
        View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.category_item,viewGroup,false);
        return new ViewHolder(view);
    }

    @Override
    public  void onBindViewHolder(@NonNull CategoryAdapter.ViewHolder holder, int position) {

    holder.bind(categoryModelList.get(position))

    }


    @Override
    public int getItemCount() {
        return categoryModelList.size();
    }


    public class ViewHolder extends  RecyclerView.ViewHolder{

       private ImageView categoryIcon;
       private TextView categoryName;

        public ViewHolder(@NonNull View itemView)  {
              super(itemView);
              categoryIcon = itemView.findViewById(R.id.category_icon);
              categoryName = itemView.findViewById(R.id.category_name);

        }

       public void bind(CategoryModel categoryModel){

             categoryName.setText(categoryModel.getCategoryName());
        }
    }
}
