1.创建带侧滑效果的activity

右击，new---->activity---->选择NavgationDrawer Activity

2.xml文件布局

(1)activity_main_function.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

    <include
        layout="@layout/app_bar_main_function"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_main_function"
        app:menu="@menu/activity_main_function_drawer" />

</android.support.v4.widget.DrawerLayout>

可以看到我们的最外层是DrawerLayout，包含了两个内容：include为显示内容区域，NavigationView为侧边抽屉栏。

NavigationView有两个app属性，分别为app:headerLayout和app:menu,headerLayout用于显示头部的布局（可选），menu用于建立MenuItem选项的菜单。

(2)nav_header_main_function.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns: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="@dimen/nav_header_height"
    android:background="@drawable/side_nav_bar"
    android:gravity="bottom"
    android:orientation="vertical"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:theme="@style/ThemeOverlay.AppCompat.Dark">

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="80dp"
        android:layout_height="80dp"
        android:contentDescription="@string/nav_header_desc"
        android:paddingTop="@dimen/nav_header_vertical_spacing"
        app:srcCompat="@mipmap/ic_account_circle_white_48dp" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingTop="@dimen/nav_header_vertical_spacing"
        android:text="@string/nav_header_title"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1" />

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/nav_header_subtitle" />

</LinearLayout>

(3)activity_main_function_drawer.xml(menu目录下)

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

    <group android:checkableBehavior="single">
        <item
            android:id="@+id/nav_me"
            android:title="我"
            android:icon="@mipmap/ic_mine_gray_24"/>
        <item
            android:id="@+id/nav_friend"
            android:title="好友"
            android:icon="@mipmap/ic_friends_gray_24"/>
        <item
            android:id="@+id/nav_notification"
            android:title="通知"
            android:icon="@mipmap/ic_notification_gray_24"/>
        <item
            android:id="@+id/nav_message"
            android:title="私信"
            android:icon="@mipmap/ic_messages_gray_24"
            />
    </group>

    <group android:checkableBehavior="none"
        android:id="@+id/group_manage">
        <item
            android:id="@+id/nav_manage"
            android:title="应用管理"
            android:icon="@mipmap/ic_app_management_gray_24"/>
    </group>

    <item android:title="Communicate">
        <menu>
            <item
                android:id="@+id/nav_share"
                android:icon="@drawable/ic_menu_share"
                android:title="分享" />
            <item
                android:id="@+id/nav_send"
                android:icon="@drawable/ic_menu_send"
                android:title="发送" />
        </menu>
    </item>

</menu>
