改变这个：

delete_img = (ImageView) itemView.findViewById(R.id.delete_img);
delete_img.setOnClickListener(this);

更改您的onclick方法，如下所示：

        @Override
        public void onClick(View v) {
            if(commentList!=null){
                commentClickListener.onItemClicked(commentList.get(getLayoutPosition()));
            }
            if (v.getId() == R.id.delete_img) {
            //do here
            }
        }

好像你做对了，不是你的

 @Override
    public void onClick(View v) {
        if(commentList!=null){  
            commentClickListener.onItemClicked(commentList.get(getLayoutPosition()));
        }
    }

被叫？或者确实：

commentList.get(getLayoutPosition())

不行吗？如果是这样，您可以尝试将其更改为：

commentList.get(getAdapterPosition())
