android.view.InflateException Binary xml 文件第 11 行：错误膨胀类片段

【中文标题】android.view.InflateException Binary xml 文件第 11 行：错误膨胀类片段【英文标题】：android.view.InflateException Binary xml file line #11: error inflating class fragment 【发布时间】：2015-02-24 06:09:37 【问题描述】：我在 SO 上找不到其他类似错误的解决方案。我收到此错误：
android.view.InflateException Binary xml file line #11: error inflating class fragment
然后看到这个是由于：
Caused by: android.view.InflateException: Binary XML file line #11: Error inflating class fragment
12-26 23:44:06.078: E/AndroidRuntime(13191): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:719)
在我的代码中，我试图通过单击按钮将 Android 手机联系人填充到 ListView 中。所以我有一个AddressBook.java，只有一个带有片段标签的xml，然后我有一个片段类，称为ContactsFragment.java. ListView 有自己的xml（fragment_list_view.xml），列表中的每一行都有自己的xml（@987654326 @)。该按钮位于MainActivity 中，上面写着查看地址簿，然后单击它会转到AddressBook.java。
但错误表明它无法放大视图。为什么？谢谢。

【问题讨论】：
【参考方案1】：事实证明存在一些问题。要使用ListFragment 为视图膨胀，我必须使用一些特殊的东西：我必须先抓取整个片段布局并将其放入视图中，然后使用我的 xml 中的id 将其投射到我的ListView ，其中必须有 id 完全命名为 android.R.id.list（根据 ListFragment docs）。然后确保return listView（而不是onCreateView() 参数中显示的默认ViewGroup）。同样对于ListFragment，必须先实例化，再将setListAdapter()实例化给它，如下图。你不能在ListView 上使用setAdapter（试过了，这是错误的）。适配器必须设置为ListFragment 的实例。
这段代码摆脱了我的InflateException 错误，但现在它显示了一个空白列表（页面为白色）。所以我将不得不进一步探索，可能与我的查询有关。
@Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container,Bundle bundle)
// since using ListFragment, you must inflate your view this way
View rootView = inflater.inflate(R.layout.fragment_list_view,
container, false);
ListView listView = (ListView) rootView
.findViewById(android.R.id.list);
// Initializes the CursorLoader. The URL_LOADER value is
// eventually passed to onCreateLoader().
getLoaderManager().initLoader(URL_LOADER, null, this);
// create adapter once
context = getActivity();
Cursor c = null; // there is no cursor yet
int flags = 0; // no auto-requery! Loader requeries.
// put List in adapter
listAdapter = new SimpleCursorAdapter(context,
R.layout.fragment_list_item, c, FROM, TO, flags);
// every time we start, use a list adapter
ListFragment listFrag = new ListFragment();
listFrag.setListAdapter(listAdapter);
return listView;
// end onCreateView
