Android设计支持库辅助抽屉菜单

Question

I've switched to the official Google Design Support Library. Now, I want to use a secondary menu with a divider like this:

But as Android is using the Menu Inflater I have no idea what to do now. I can add a second group, but then the items have the same size and there is no divider.

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>

            @Override
            public void onDrawerClosed(View drawerView) {
                // Code here will be triggered once the drawer closes as we dont want anything to happen so we leave this blank

            @Override

        //calling sync state is necessay or else your hamburger icon wont show up
        actionBarDrawerToggle.syncState();






    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

So, how can I create a menu like this, or how can I add dividers (with category headers) to my navigation drawer?

Answer 1

You can use the standard NavigationView defining a menu like this:

<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>

It is important to give an unique id to each group.

Tutorial: Navigation View Design Support Library

Menu Items:

<?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>

</menu>

Here is what you exactly looking for:

<?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>

You can use any ViewGroup like a LinearLayout for your Drawer. It is not limited to a ListView and a FrameLayout. Because of this you can style your Drawer View like any other layout of an Activity for example. The only thing you should keep in mind is that the NavigationDrawer can have only two childs. The first is your layout for the Activity and the second is the Drawer. Feel free to style them as you like!

<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>

for the divider

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