我正在尝试为导航抽屉添加不同的视图。我使用Android Studio创建了导航抽屉，它确实创建了导航抽屉，将其内容作为片段，因此旧教程不起作用。
这是我的主要活动布局：
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.app.MainActivity">
<!-- As the main content view, the view below consumes the entire
space available using match_parent in both dimensions. -->
<FrameLayout
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- android:layout_gravity="start" tells DrawerLayout to treat
this as a sliding drawer on the left side for left-to-right
languages and on the right side for right-to-left languages.
If you're not building against API 17 or higher, use
android:layout_gravity="left" instead. -->
<!-- The drawer is given a fixed width in dp and extends the full height of
the container. -->
<fragment android:id="@+id/navigation_drawer"
android:layout_width="@dimen/navigation_drawer_width"
android:layout_height="match_parent"
android:layout_gravity="start"
android:name="com.example.app.NavigationDrawerFragment"
tools:layout="@layout/fragment_navigation_drawer" />
</android.support.v4.widget.DrawerLayout>
fragment_navigation_drawer.xml：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/navigation_drawer_linear">
<ListView
android:id="@+id/navigation_drawer_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:choiceMode="singleChoice"
android:divider="@layout/list_divider"
android:background="#cccc"
android:dividerHeight="1px"
tools:context="com.example.app.NavigationDrawerFragment"/>
</LinearLayout>
通常，没有LinearLayout，我自己添加了它。我试图改变工作室生成的代码中唯一的东西是在NavigationDrawerFragment的onCreateView中：
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View drawerView = inflater.inflate(
R.layout.fragment_navigation_drawer, container, false);
mDrawerListView = (ListView) drawerView.findViewById(R.id.navigation_drawer_list);
// mDrawerListView = (ListView) inflater.inflate(
// R.layout.fragment_navigation_drawer, container, false);
// ...
评论的部分是以前的。如果我删除LinearLayout并将ListView保留在fragment_navigation_drawer.xml中，它可以正常工作。我不知道还有什么方法可以让它发挥作用。
修改
当我尝试启动它时应用程序崩溃，这是logcat输出：

答案 0 :(得分：3)
必须更改NavigationDrawerFragment.onCreateView从
返回的视图return mDrawerListView
到
return drawerView
