运行时错误膨胀片段

错误： java.lang.RuntimeException：无法启动活动ComponentInfo {com.example.todolist/com.example.todolist.ToDoListActivity}：android.view.InflateException：二进制XML文件行＃6 ：错误膨胀类片段运行时错误膨胀片段

我知道这个问题已被问过，但我已经通过他们搜索，找不到解决方案。我发现应用程序启动后几秒钟没有碰到任何东西，这个错误不会加载，然后崩溃。

我有一个FragmentActivity类中有两个片段（ListFragment和EditText）。我的sdk支持是7，所以我使用支持库导入。

这是FragmentActivity的代码：

public class ToDoListActivity extends FragmentActivity 
     implements NewItemFragment.OnNewItemAddedListener{ 

private ArrayList<String> todoItems; 
private ArrayAdapter<String> aa; 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_to_do_list); 

    FragmentManager fm = getSupportFragmentManager(); 
    ToDoListFragment toDoListFragment = (ToDoListFragment) 
      fm.findFragmentById(R.id.ToDoListFragment); 




    aa = new ArrayAdapter<String>(this, 
        android.R.layout.simple_list_item_1, 
         todoItems); 

    toDoListFragment.setListAdapter(aa); 


} 

public void onNewItemAdded(String newItem){ 
    todoItems.add(newItem); 
    aa.notifyDataSetChanged(); 

}

这是FragmentActivity的布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" > 

<fragment 
    android:id="@+id/NewItemFragment" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:name="com.example.todolist.NewItemFragment"/> 

<fragment 
    android:id="@+id/ToDoListFragment" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:name="com.example.todolist.ToDoListFragment" /> 
</LinearLayout>

这是的EditText片段代码：

public class NewItemFragment extends Fragment { 

private OnNewItemAddedListener onNewItemAddedListener; 

public interface OnNewItemAddedListener { 
    public void onNewItemAdded(String newItem); 
} 

@Override 
public void onAttach(Activity activity) { 
super.onAttach(activity); 

try { 
onNewItemAddedListener = (OnNewItemAddedListener)activity; 
}catch (ClassCastException e) { 
    throw new ClassCastException(activity.toString() + 
      "must implement OnNewItemAddedListener"); 
    } 
} 

public View OnCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState){ 

    View view = inflater.inflate(R.layout.new_item_fragment, container 
      , false); 

    final EditText myEditText = (EditText)view.findViewById(R.id.myEditText); 

    myEditText.setOnKeyListener(new View.OnKeyListener() { 

     ... 
    }); 
    return view; 
}

}

这是片段的EditText布局：

<EditText xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/myEditText" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:hint="@string/addItemHint" 
    android:contentDescription="@string/addItemContentDescription" />

我ListFragment类使用默认的布局，所以我只创建了类声明一个.java文件（类名与片段活动XML中所写的名称相同）

这剩余的LogCa T：

实际的错误是Fragment com.example.todolist.NewItemFragment did not create a view.

这是发生，因为你有一个名为OnCreateView，而不是onCreateView方法。该方法应以小写字母开头。如果您将该方法标记为@Override，则会显示此错误。
