Android 设计支持库二级抽屉菜单

Android Design Support Library Secondary Drawer Menu

我已经切换到官方 Google 设计支持库。现在,我想使用带有这样分隔线的二级菜单:

但是由于 Android 正在使用 Menu Inflater,我现在不知道该怎么做。我可以添加第二组,但这样项目的大小相同并且没有分隔符。

drawer.xml:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <group android:checkableBehavior="single">

        <item
            android:id="@+id/overview"
            android:checked="true"
            android:icon="@drawable/ic_action_dashboard"
            android:title="@string/drawer_overview" />

        <item
            android:id="@+id/social_evening"
            android:checked="false"
            android:icon="@drawable/ic_action_brightness_3"
            android:title="@string/drawer_social_evening" />

        <item
            android:id="@+id/scouting_games"
            android:checked="false"
            android:icon="@drawable/ic_action_landscape"
            android:title="@string/drawer_scouting_games" />

        <item
            android:id="@+id/olympics"
            android:checked="false"
            android:icon="@drawable/ic_action_stars"
            android:title="@string/drawer_olympics" />


        <item
            android:id="@+id/quizzes"
            android:checked="false"
            android:icon="@drawable/ic_action_school"
            android:title="@string/drawer_quizzes" />

    </group>
</menu>

那么,如何创建这样的菜单,或者如何将分隔线(类别为 headers)添加到我的导航抽屉中?

您可以为抽屉使用任何 ViewGroup,例如 LinearLayout。它不限于 ListView 和 FrameLayout。因此,您可以像 Activity 的任何其他布局一样设置抽屉视图的样式。您唯一应该记住的是 NavigationDrawer 只能有两个孩子。第一个是 Activity 的布局,第二个是抽屉。随心所欲地设计它们!

<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
    android:id="@+id/content_frame"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<!-- YOUR DRAWER -->
<LinearLayout
    android:id="@+id/drawer_view"
    android:layout_width="240dp"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:layout_gravity="start">

    <!-- Use any Views you like -->
    <ListView
        android:id="@+id/left_drawer"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp"
        android:background="#ffffff"/>
</LinearLayout>
</android.support.v4.widget.DrawerLayout>

用于分隔线

android:divider="#FFFFFF"
android:dividerHeight="1dp"

您可以使用标准 NavigationView 定义如下菜单:

<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <group android:id="@+id/group1" android:checkableBehavior="single" id>
       //items of group1
    </group>

    <group android:id="@+id/group2" android:checkableBehavior="single" id>
       //items of group2
    </group>

给每个组一个唯一的 ID 很重要。

菜单项:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <group android:checkableBehavior="single">
        <item
            android:id="@+id/navigation_item_attachment"
            android:checked="true"
            android:icon="@drawable/ic_attachment"
            android:title="@string/nav_item_attachment" />
        <item
            android:id="@+id/navigation_item_images"
            android:icon="@drawable/ic_image"
            android:title="@string/nav_item_images" />
        <item
            android:id="@+id/navigation_item_location"
            android:icon="@drawable/ic_place"
            android:title="@string/nav_item_location" />
    </group>

    <item android:title="@string/nav_sub_menu">
        <menu>
            <item
                android:icon="@drawable/ic_emoticon"
                android:title="@string/nav_sub_menu_item01" />
            <item
                android:icon="@drawable/ic_emoticon"
                android:title="@string/nav_sub_menu_item02" />
        </menu>
    </item>

</menu>

这就是您要查找的内容:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <group android:checkableBehavior="single">

        <item
            android:id="@+id/Home"
            android:checked="false"
            android:icon="@drawable/ic_home"
            android:title="@string/homestr" />
        <item
            android:id="@+id/myacc"
            android:checked="false"
            android:icon="@drawable/ic_account"
            android:title="@string/myaccstr" />
        <item
            android:id="@+id/popular"
            android:checked="false"
            android:icon="@drawable/ic_star"
            android:title="@string/Popularstr" />

        <item
            android:id="@+id/newsit"
            android:checked="false"
            android:icon="@drawable/ic_news"
            android:title="@string/newsstr" />


        <item android:title="@string/gn">
            <menu>
                <item
                    android:id="@+id/settings"
                    android:checked="false"
                    android:icon="@drawable/ic_setting"
                    android:title="@string/action_settings" />
                <item
                    android:id="@+id/help"
                    android:checked="false"
                    android:icon="@drawable/ic_help"
                    android:title="@string/helpstr" />

            </menu>
        </item>
    </group>
</menu>
