Java-Recycleview viewholder.category_name.settext不起作用

Question

@Override
            protected void populateViewHolder(CategoryViewHolder viewHolder, Category model, int i) {
                viewHolder.category_name.setText(model.getName());
                Picasso.with(getActivity())
                        .load(model.getImage())
                        .into(viewHolder.category_image);

                viewHolder.setItemClickListener(new ItemClickListener() {
                    @Override
                    public void onClick(View view, int position, boolean isLongClick) {
//                        FancyToast.makeText(getActivity(),String.format("%d|%s",adapter.getRef(position).getKey(),model.getName()),FancyToast.LENGTH_LONG,FancyToast.SUCCESS,true).show();
                        Intent startGame = new Intent(getActivity(),Start.class);
                        Common.categoryId = adapter.getRef(position).getKey();
                        startActivity(startGame);
                    }
                });
            }
        };

我尝试了以下代码，但是viewHolder.category_name.setText（）无法正常工作 实际上setText可以正常工作，但是model.getName（）不能正常工作
