无效指数3，大小为0 - 指标均crashlytics随机。
我使用与片段页眉和页脚的ListView。

Invalid index 3, size is 0 - indexes are Random in crashlytics. I am using ListView with header and footer in fragment.

在 onCreateView

mSearchBox = inflater.inflate(R.layout.search_box, mListView, false);
mListView.addHeaderView(mSearchBox, null, false);
mListView.setAdapter(mAdapter);
mAdapter.notifyDataSetChanged();

我用头球为的ListView为的EditText ListView中搜索（故意，因为我想那是的EditText与滚动列表视图的内容）。同时，我用addFooterView用于显示加载器（列表中的下一个加载项时）。

I use header in ListView for EditText for searching in ListView (purposely because I want that EditText is scrollable with listview content). And also I use addFooterView for showing loader (when loading next items in list).

您可以看一下HeaderViewListAdapter线225（<一个href=\"http://grep$c$c.com/file/repository.grep$c$c.com/java/ext/com.google.android/android/4.4.4_r1/android/widget/HeaderViewListAdapter.java/#224\"相对=nofollow> grep的code ）：

You can look at HeaderViewListAdapter line 225 (GrepCode):

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

// Footer (off-limits positions will throw an IndexOutOfBoundsException)
return mFooterViewInfos.get(adjPosition - adapterCount).view;
}

编辑：
我发现similiar计算器线程，但它是不适合我有帮助：<一href=\"http://stackoverflow.com/questions/6950069/indexoutofboundsexception-with-listview\">Indexoutofboundsexception与列表视图
看起来Android的ListView控件是有点用ListView的页眉或页脚片段时窃听。

I have found similiar stackoverflow thread but It is not helpful for me: Indexoutofboundsexception with listview Looks like android ListView is a bit bugged when using header or footer in ListView with fragments.

推荐答案

我不得不设置列表视图空适配器之前，我正在收拾适配器：

I had to set null adapter on listview before I was clearing the adapter:

mListView.setAdapter(null);
mAdapter.clear();
mAdapter.notifyDataSetChanged();
mListView.setAdapter(mAdapter);
