这是我想在我的片段类中找到 textview （viewHolder.tv_number）的 getview 方法 . 我怎样才能做到这一点？

@Override
public View getView(final int position, View view, ViewGroup parent) {
    LayoutInflater layoutInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    if (view == null) {
        view = layoutInflater.inflate(R.layout.category, parent, false);

        viewHolder = new ViewHolder();
        viewHolder.Dish_name = (TextView) view.findViewById(R.id.nameofdish);
        viewHolder.dish_description = (TextView) view.findViewById(R.id.dishdescription);
        viewHolder.Dish_rate = (TextView) view.findViewById(R.id.rateofdish);
        viewHolder.item_image = (ImageView) view.findViewById(R.id.img_item);
        viewHolder.tv_Number = (TextView) view.findViewById(R.id.tv_add_sub);
        viewHolder.mBtnAdd = (Button) view.findViewById(R.id.btn_add);
        viewHolder.mBtnMinus = (Button) view.findViewById(R.id.btn_sub);
    } 
}

    使用此代码

    //set adapter class
    customButtonListener customListner;

        public interface customButtonListener {
            public void onClickButton(int position);
        }

        public void setCustomButtonListner(customButtonListener listener) {
            this.customListner = listener;
        }

    //set click listner

    viewHolder.mBtnAdd.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View v) {

                               customListner.onClickButton(pass data);
                        }
                    });

    //Implement in adapter 

    adapter.setCustomButtonListner(Fragment.this);

    //Overide method

    @Override
        public void onClickButton(String song_id)
        {
           // Your custom click event here...
        }
