Question

我尝试使用Navigation Drawer向Activity添加自定义ListView。在我添加Navigation Drawer之前，ListView可以滚动，您可以选择项目，但是当我添加抽屉时，它不再执行此操作。当我在ListView上方添加Navigation Drawer时，Navigation Drawer有效。但是，当我将ListView置于其下时，Navigation Drawer无效。

如果要使用导航抽屉，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>

Android：ListView在添加抽屉时不会滚动
