java - 没有编译错误，但是当运行代码单击评论按钮时，它不会导致我想要的活动

Question

我做了下面的代码，使用适配器来显示列表，并使用一个按钮来向列表项添加评论，它在单击评论按钮时显示 logcat“ViewPostIme 指针 0 和 ViewPostIme 指针 1”。

编译后它没有显示任何错误，我尝试通过谷歌使用许多参考，但没有任何效果。

我的基本想法是调用带有关联列表项的评论按钮来执行评论活动。

适配器类

public class PostsAdapter extends FirestoreRecyclerAdapter<PostsModel, PostsAdapter.PostsHolder> {
    private OnItemClickListener listener;
    private View.OnClickListener buttonListener;


    private String id;

    private static final String TAG = "DocSnippets";


    public PostsAdapter(@NonNull FirestoreRecyclerOptions<PostsModel> options) {
        super(options);
    }

    @Override
    protected void onBindViewHolder(@NonNull PostsHolder holder, int position, @NonNull PostsModel model) {
        //retrieve the fields here
        holder.textViewDescription.setText(model.getPostContent());
        holder.textViewPriority.setText(String.valueOf(model.getSpinnerC()));
        holder.textViewPriority.setText(String.valueOf(model.getTimestamp()));
    }

    @NonNull
    @Override
    public PostsHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.post_list_layout,
                parent, false);
        return new PostsHolder(v);
    }

    public void deleteItem(int position) {
        getSnapshots().getSnapshot(position).getReference().delete();
    }

    public void setOnClickListener(OnClickListener postKey) {
    }


    class PostsHolder extends RecyclerView.ViewHolder {

        //first declare here the elements to be displayed in the cardview.
        TextView textViewTitle;
        TextView textViewDescription;
        TextView textViewPriority;

        Button commentsbutton;

        public PostsHolder(final View itemView) {
            super(itemView);
            textViewTitle = itemView.findViewById(R.id.post_etPostTitle);
            textViewDescription = itemView.findViewById(R.id.post_description);
            textViewPriority = itemView.findViewById(R.id.post_time);
             commentsbutton = itemView.findViewById(R.id.commenting_button);


            commentsbutton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    int position = getAdapterPosition();
                    if (position != RecyclerView.NO_POSITION && buttonListener != null) {
                        buttonListener.onClick(itemView);

                    }

                }
            });
        }
    }

    public interface OnClickListener
    {
        void OnClickListener(DocumentSnapshot documentSnapshot, int position);

    }
    public void setOnClickListener(View.OnClickListener onClickListener) {
        this.buttonListener = onClickListener;
    }


    public interface OnItemClickListener {
        void onItemClick(DocumentSnapshot documentSnapshot, int position);
    }

    public void setOnItemClickListener(OnItemClickListener listener) {
        this.listener = listener;
    }
}
