notifyDataSetChanged（）不适用于自定义列表视图

Question

我的主要活动有一个哈希映射，它从parse-server获取数据以传递到自定义列表视图适配器类。

当我单击列表视图行中的按钮时，我希望每次单击时都会更改文本。但是，仅在单击按钮一次时，行中的文本才会更改。如果我再次点击它，没有任何反应。我假设这与我有关，我的notifyDataSetChanged()被错误地调用了。

按钮和textview都在自定义列表视图适配器类中设置。我可以在主活动或自定义列表视图适配器类中调用notifyDataSetChanged()吗？

我的MainActivity中的customFeedListViewAdapter.notifyDataSetChanged();允许我在单击按钮一次时成功更改文本。但是，当我再次单击该按钮时，没有任何反应。

主要活动：

  customFeedListViewAdapter = new CustomFeedListViewAdapter(this, arrayFeedList);
    feedList = (ListView) findViewById(R.id.feedListView);
    feedList.setAdapter(customFeedListViewAdapter);


    ParseQuery<ParseObject> query = new ParseQuery<ParseObject>("FeedItem");
    ParseUser.getCurrentUser().getUsername());
    query.addDescendingOrder("createdAt");


    query.findInBackground(new FindCallback<ParseObject>() {
        @Override
        public void done(List<ParseObject> objects, ParseException e) {

            if(e == null){

                    for(ParseObject object: objects){

                        HashMap<String, String> data = new HashMap<String, String>();
                        data.put("user", (object.getString("username")));
                        data.put("feed", (object.getString("textItem")));
                        data.put("likes", String.valueOf(object.getInt("likes")));
                        data.put("replies",String.valueOf(object.getInt("comments")));

                        object.saveInBackground();


                        arrayFeedList.add(data);
                        customFeedListViewAdapter.notifyDataSetChanged();


                    }

                     customFeedListViewAdapter = new CustomFeedListViewAdapter(getApplicationContext(), arrayFeedList);
                    feedList.setAdapter(customFeedListViewAdapter);

            }

        }
    });

自定义ListView适配器：

  @Override
public View getView(final int i, View view, ViewGroup viewGroup) {

     position = i;
    final int likes[] = new int[feed.size()];

    final ViewHolder holder;

    if (view == null) {

        view = inflater.inflate(R.layout.feed_list_row, viewGroup, false);

        holder = new ViewHolder();

        holder.feedProfilePic = (ImageView) view.findViewById(R.id.feedProfilePic);
        holder.feedUsername = (TextView) view.findViewById(R.id.feedUsernameId);
        holder.feedNumOfLikes = (TextView) view.findViewById(R.id.feedNumofLikes);
        holder.feedFeedItem = (TextView) view.findViewById(R.id.feedTextId);
        holder.feedDate = (TextView) view.findViewById(R.id.feedDate);
        holder.feedNumofReplies = (TextView) view.findViewById(R.id.feedRepliesNumId);
        holder.feedUpVoteButton = (Button) view.findViewById(R.id.feedUpVoteButton);
        holder.feedDownVoteButton = (Button) view.findViewById(R.id.feedDownVoteButton);
        holder.feedCommentButton = (Button) view.findViewById(R.id.feedCommentButton);
        holder.feedListView = (ListView) view.findViewById(R.id.feedListView);

        view.setTag(holder);

        HashMap<String, String> mFeed = new HashMap<>();

        mFeed = feed.get(i);

        holder.feedUsername.setText(mFeed.get("user"));
     holder.feedFeedItem.setText(mFeed.get("feed"));
       holder.feedDate.setText(mFeed.get("date"));
        holder.feedNumOfLikes.setText(mFeed.get("likes"));
        likesString = mFeed.get("likes");
         mLikes = Integer.valueOf(likesString);

        holder.feedNumofReplies.setText(mFeed.get("replies"));

        position = i;

    }
    else{
        position = i;
        holder = (ViewHolder) view.getTag();
    }

    holder.feedUpVoteButton.setTag(position);
    holder.feedDownVoteButton.setTag(position);

                            @Override
                            public void onClick(View v) {


                                int pos = (Integer) v.getTag();

                                parseObFeed = objects.get(pos);

                                    parseObFeed.put("likes", likes[pos]);

                                Log.i("yo","Check3: Put Likes in Parse:   " + String.valueOf(likes[pos]));


                                    parseObFeed.put("upClicked", true);
                                    parseObFeed.saveInBackground();
                                    holder.feedNumOfLikes.setText(String.valueOf(parseObFeed.getInt("likes")
