android - ArrayOutOfBounds 将 addHeaderView() 与 EndlessAdapter 一起使用时

Question

我正在使用 Commonsware 的 EndlessAdapter。当我添加了一个 header View 时，我得到了我的 listView，我得到了这个错误和 LogCat:

如果我删除 headerview，我就过了这一点。

补充:这是与标题 View 无关的其他代码:

public class EndlessProfileAdapter extends EndlessAdapter implements
            IItemsReadyListener {

        private boolean hasMoreData = true;
        private RotateAnimation rotate = null;
        private View pendingView = null;
        private ArrayList<ProfileReview> profileList;

        public EndlessProfileAdapter(Context context,
                ArrayList<ProfileReview> profileList, Typeface tf) {
            super(new ProfileAdapter(context, profileList, tf));

            this.profileList = profileList;

            rotate = new RotateAnimation(0f, 360f, Animation.RELATIVE_TO_SELF,
                    0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
            rotate.setDuration(600);
            rotate.setRepeatMode(Animation.RESTART);
            rotate.setRepeatCount(Animation.INFINITE);

        }

@Override
protected boolean cacheInBackground() throws Exception {
    Log.d("Cache Array Size", String.valueOf(profileList.size()));
    new ReviewTask(this, profileList.size()).execute();
    return hasMoreData;
}

@Override
protected void appendCachedData() {

}

void startProgressAnimation() {
    if (pendingView != null) {
        pendingView.startAnimation(rotate);
    }
}

public void onItemsReady(ArrayList<ProfileReview> data) {

    profileList.addAll(data);
    endlessAdapter.onDataReady();
    hasMoreData = profileList.isEmpty();
}

内部任务 onPostExecute():

profileList = new ArrayList<ProfileReview>();

            for (int i = startPoint; i < startPoint + 10; i++) {
                ProfileReview p = new ProfileReview(itemIdList.get(i),
                        reviewIdList.get(i), reviews.get(i), datelist.get(i),
                        itemslist.get(i), ratings.get(i), cats.get(i));
                profileList.add(p);
            }

            return profileList;

EndlessAdapter 以列表中的十个为一组。前 10 个工作...但在 11 个时，它崩溃了。 LogCat 崩溃实际上发生在第二轮 10(因此用户滚动到列表中的前 10 个之后的第 11 个项目)，并在 profileList.add(p);

更新了请求的信息

在 onActivityCreated() 中:

       // for adapter constructor 
       tf = Typeface.createFromAsset(getActivity().getAssets(),
            "fonts/listitemfont.ttf");


   LayoutInflater inflater = getActivity().getLayoutInflater();

    ViewGroup header = (ViewGroup) inflater.inflate(
            R.layout.profile_header, listView, false);

    listView = getListView();
    listView.addHeaderView(header, null, false);

            // stuff like settings up buttons inside header

            // just before end of  `onActivityCreated()`

        if (endlessAdapter == null) {
           if (getActivity() != null) {

            profileList = new ArrayList<ProfileReview>();
            endlessAdapter = new EndlessProfileAdapter(getActivity(),
                    profileList, tf);
            endlessAdapter.setRunInBackground(false);
            listView.setAdapter(endlessAdapter);
        }
    }

Answer 1

EndlessAdapter 将无法支持页眉或页脚 View 。当您使用页眉或页脚 View 时创建的 HeaderListViewAdapter 对底层适配器做出了一些假设，而 EndlessAdapter 并非总是如此。

我已经更新了 EndlessAdapter 文档以指出限制。
