Android 如何将布局添加到导航抽屉？

我从Android Studio创建了一个导航抽屉项目。现在我想在导航抽屉中添加一个线性布局。所以我加了它。但它显示了这样一个错误

关于导航抽屉碎片

我引用了这个答案，但没有用

导航抽屉

在片段的onCreateView方法中，您将使用LinearLayout作为根元素扩展布局，然后尝试将其强制转换为ListView。将该方法中的第一行更改为：

View rootView = inflater.inflate(
    R.layout.fragment_navigation_drawer, container, false);
mDrawerListView = (ListView) rootView.findViewById(R.id.drawer_list);

然后改变回报 声明：

 return rootView;

并将以下ID添加到布局xml中的ListView：

 android:id="@+id/drawer_list"

---

上面是这样写的？指定的子级已具有父级。您必须首先调用子级的父级上的removeView。它显示线性布局，但Listview现在隐藏了吗？怎么办？在内线布局上，更改：布局\高度=包裹\内容。然后，在ListView上，更改：layout\u height=0dp和add:layout\u weight=1。老实说，我只是通过查看开发人员关于堆栈溢出的文档和答案来了解它们。我不知道有什么好的，单一的网站可以推荐。不过，这里有很多例子！：-让我们。

Caused by: java.lang.ClassCastException: android.widget.LinearLayout cannot be cast to android.widget.ListView

View rootView = inflater.inflate(
    R.layout.fragment_navigation_drawer, container, false);
mDrawerListView = (ListView) rootView.findViewById(R.id.drawer_list);

 return rootView;

 android:id="@+id/drawer_list"
