xml中设置

<android.support.v4.widget.DrawerLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"android:layout_width="match_parent"android:layout_height="match_parent"android:fitsSystemWindows="true"android:id="@+id/drawerLayout"><!--主布局--><FrameLayout    android:id="@+id/framLayout"    android:layout_width="match_parent"    android:layout_height="0dp"    android:layout_weight="1"></FrameLayout><!--侧滑布局--><android.support.design.widget.NavigationView    android:id="@+id/left_view"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:fitsSystemWindows="true"    android:layout_gravity="left"    app:headerLayout="@layout/headlayout"    app:menu="@menu/menu"></android.support.design.widget.NavigationView>

说明
app:headerLayout：侧滑头部的布局
app:menu：侧滑列表的引用（menu资源文件）

<menu xmlns:android="http://schemas.android.com/apk/res/android"  xmlns:app="http://schemas.android.com/apk/res-auto">    <group android:checkableBehavior="single">        <item            android:id="@+id/home"            android:icon="@mipmap/ic_home_white_24dp"            android:title="Home"/>        <item            android:id="@+id/book"            android:icon="@mipmap/ic_book_white_24dp"            android:title="Book"/>        <item            android:id="@+id/music"            android:icon="@mipmap/ic_music_note_white_24dp"            android:title="Music"/>        <item            android:id="@+id/movie"            android:icon="@mipmap/ic_tv_white_24dp"            android:title="Movie"/>        <item            android:id="@+id/favorite"            android:icon="@mipmap/ic_favorite_white_24dp"            android:title="favorite"/>    </group>    <item android:title="dfsd">        <menu>            <item                android:id="@+id/help"                android:icon="@mipmap/ic_menu_help"                android:title="Help"/>            <item                android:id="@+id/info"                android:icon="@mipmap/ic_menu_info_details"                android:title="Info"/>            <item                android:id="@+id/infos"                android:title=""/>        </menu>    </item></menu>
