Question

我在碰撞中遇到随机崩溃，我无法模拟它。它在Android V2和V4上随机崩溃，但非常非常：

索引3无效，大小为0 - 在crashlytics中索引是随机的。我在片段中使用带有页眉和页脚的ListView。

在 onCreateView ：

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

我使用ListView for EditText中的标题在ListView中进行搜索（故意因为我希望EditText可以使用listview内容进行滚动）。我还使用addFooterView显示加载器（在列表中加载下一个项目时）。

您可以查看HeaderViewListAdapter第225行（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;
}

修改我找到了类似的stackoverflow线程，但它对我没有帮助：Indexoutofboundsexception with listview 看起来像在ListView中使用带有片段的页眉或页脚时，android ListView有点麻烦。

Answer 1

在清除适配器之前，我必须在listview上设置null适配器：

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

HeaderViewListAdapter随机崩溃
