Android设计支持库辅助抽屉菜单
我已切换到官方Google设计支持库。现在，我想使用带有分隔符的二级菜单：
但是由于Android正在使用Menu Inflater，我不知道现在该做什么。我可以添加第二组，但是这些项目具有相同的大小，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>
MainActivity.java：
package net.sutomaji.freizeitspiele;

import android.support.design.widget.NavigationView;
import android.support.v4.app.FragmentTransaction;
import android.support.v4.widget.DrawerLayout;

}
};
//Setting the actionbarToggle to drawer layout
drawerLayout.setDrawerListener(actionBarDrawerToggle);
//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

int id = item.getItemId();
//noinspection SimplifiableIfStatement

return super.onOptionsItemSelected(item);
}
}
那么，我该如何创建这样的菜单，或者如何在导航抽屉中添加分隔符（带有类别标题）？

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>
为每个组提供唯一ID非常重要。

您可以将任何ViewGroup（如LinearLayout）用于抽屉。它不仅限于ListView和FrameLayout。因此，您可以像绘制活动的任何其他布局一样设置抽屉视图的样式。你应该记住的唯一事情是NavigationDrawer只能有两个孩子。第一个是Activity的布局，第二个是Drawer。随意设置它们的样式！
<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>
表示分隔符
android:divider="#FFFFFF"
android:dividerHeight="1dp"
