Android：添加抽屉时ListView不会滚动

Question

我尝试使用ListView 将自定义Navigation Drawer 添加到Activity。 在我添加Navigation Drawer 之前，ListView 可以滚动并且您可以选择项目，但是当我添加抽屉时它不再这样做了。 当我在Navigation Drawer 上方添加ListView 时，Navigation Drawer 有效。 但是当我把ListView放在它下面时，Navigation Drawer就不起作用了。

    <include layout="@layout/content_my_library" /> //when I put this above it the drawer works but then the listview doesn't scroll and cant be selected.

Content_my_library：

        android:layout_width="match_parent">
    </ListView>

</RelativeLayout>

如果您想使用抽屉式导航，请将 DrawerLayout 设为根元素。

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.CoordinatorLayout>
        <!-- All the things. -->
    </android.support.design.widget.CoordinatorLayout>

    <ListView
        android:id="@+id/navList"/>

</android.support.v4.widget.DrawerLayout>
