我在打开和关闭它时创建了一个侧边导航，点击一切都很好的图标。当侧面导航并尝试通过单击其边缘应用程序来关闭它时失败。有什么问题？这是我的代码：

您可以FragmentLayout with layout_width/layout_height = match_parent property在主布局中添加。如果您不需要这个，请不要FragmentLayout在您的活动中使用/调用。我知道，这不是一个好的解决方案，但是，它对我有用。

我没有看到 .closeDrawer() 在任何地方被调用。

我知道这是一篇旧文章，但我找到了这个解决方案，它可能会对未来的读者有所帮助。

如果您不希望您的抽屉布局覆盖整个屏幕并仍然解决问题，请检查您是否在片段布局中添加了任何边距（在您的布局 xml 中）。

如果是，则删除它们，这应该可以解决。这听起来很奇怪，但它确实有效。:)

根据有关创建导航抽屉的 Android Doc，您需要为android.support.v4.widget.DrawerLayout具有两个子视图的布局创建为根：FragmentLayout和ListView

因为 the XML order implies z-ordering and the drawer must be on top of the content.

如果您不需要使用FragmentLayout视图，则可以将其设为visibilityisgone

<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">

      <!-- Framelayout to display Fragments -->
    <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:visibility="gone" />

    <!-- Listview to display slider menu -->
    <ListView
        android:id="@+id/list_slidermenu"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice"
        android:divider="@color/list_divider"
        android:dividerHeight="1dp"        
        android:listSelector="@drawable/list_selector"
        android:background="@color/list_background"/>
</android.support.v4.widget.DrawerLayout>

如果您需要创建多个，FragmentLayout您可以创建RelativeLayout或LinearLayout作为第一个 Child for android.support.v4.widget.DrawerLayoutRoot 视图

<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">

    <RelativeLayout android:layout_width="match_parent"
                    android:layout_height="match_parent" >

        <FrameLayout android:id="@+id/fragment_first"
                     android:layout_width="fill_parent"
                     android:layout_height="wrap_content" >
        </FrameLayout>

        <FrameLayout android:id="@+id/fragment_second"
                     android:layout_width="fill_parent"
                     android:layout_height="fill_parent"
                     android:layout_belo="@id/fragment_first" >

        </FrameLayout>

    </RelativeLayout>

        <!-- Listview to display slider menu -->
        <ListView
            android:id="@+id/list_slidermenu"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            android:choiceMode="singleChoice"
            android:divider="@color/list_divider"
            android:dividerHeight="1dp"        
            android:listSelector="@drawable/list_selector"
            android:background="@color/list_background"/>
</android.support.v4.widget.DrawerLayout>
