Question

我有一个非常奇怪的错误，我无法理解。以下是视频格式http://www.youtube.com/watch?v=hHuUzNDI68w

中的行为

现在解释一下。我有一个名为NewsFeed的活动。它包含一个FeedView的ListView（每个都有一个来自url的照片，我使用缓存类加载，旁边有一些文本）如果我打开这个活动，一切都没问题，当我滚动所有内容时按预期工作。但是，如果我首先按下搜索键，其中键盘出现，并且我从搜索结果中选择了某些内容，则会打开NewsFeed活动首先当它出现时，键盘仍然是向上，然后一瞬间键盘向下，最终结果是顶部的2个图像是相同的（它们不应该是）

通过一些调试我发现由于某种原因，前2行的viewHolder最终成为第二轮的同一个对象（一旦键盘终于消失了）

public View getView (int position, View convertView, ViewGroup parent) {

        final HashMap<String, Object> game = getItem(position);
        CollapsedNewsHolder collapsedNewsHolder;
        if (convertView == null) {
            convertView = inflater.inflate(R.layout.news_collapsed_module, null);
            collapsedNewsHolder = new CollapsedNewsHolder();
            collapsedNewsHolder.newsPicture = (ImageView) convertView.findViewById(R.id.NewsPicture);
            collapsedNewsHolder.progress = (ProgressBar) convertView.findViewById(R.id.Progress);
            collapsedNewsHolder.title = (TextView) convertView.findViewById(R.id.title);
            collapsedNewsHolder.newsPerson = (TextView) convertView.findViewById(R.id.newsPerson);
            collapsedNewsHolder.upCount = (TextView) convertView.findViewById(R.id.upCount);
            collapsedNewsHolder.commentCount = (TextView) convertView.findViewById(R.id.commentCount);
            collapsedNewsHolder.relativeTime = (TextView) convertView.findViewById(R.id.RelativeTime);
            collapsedNewsHolder.setTypeface();

            //collapsedNewsHolder.imageCallback = new MyImageCallback(mActivity, collapsedNewsHolder.newsPicture, collapsedNewsHolder.progress, MyImageCallback.SMALL, 200);
            //collapsedNewsHolder.itemClickListener = new ItemClickListener();

            convertView.setTag(collapsedNewsHolder);
        } else
            collapsedNewsHolder = (CollapsedNewsHolder) convertView.getTag();

        if ((Integer) getItem(position).get("type") != NewsFeed.POSTER)
            collapsedNewsHolder.title.setTextSize(13f);

        collapsedNewsHolder.newsPicture.setImageBitmap(null);
        collapsedNewsHolder.progress.setVisibility(View.VISIBLE);
        ImageUtil.imageCache.loadAsync((String) game.get("img"), new MyImageCallback(mActivity, collapsedNewsHolder.newsPicture, collapsedNewsHolder.progress, MyImageCallback.SMALL, 200), mContext);

        collapsedNewsHolder.title.setText((String) game.get("title"));
        collapsedNewsHolder.newsPerson.setText((String)game.get("newsPerson"));

        collapsedNewsHolder.relativeTime.setText((String) game.get("relativeTime"));
        collapsedNewsHolder.upCount.setText((Integer) game.get("upCount") + "");
        collapsedNewsHolder.commentCount.setText((Integer) game.get("commentCount") + "");
        //convertView.setOnClickListener(collapsedNewsHolder.itemClickListener.set((String) game.get("id"), position));
        convertView.setOnClickListener(new ItemClickListener((String) game.get("id"), position));
        return convertView;
    }

此处还有一个说明问题的错误日志。请注意关于列表中位置的内存位置和图像URL。

Answer 1

我有类似的问题。我通过将android:windowSoftInputMode设置为adjustPan来解决此问题。

隐藏键盘时，ListView会将项目回收到错误的位置
