话不多说先上效果演示
演示
还包括了NavigationView（导航抽屉）的效果，不会的可以先看
NavigationView（导航抽屉）

MainActivity的布局
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
android:id="@+id/drawer_layout"
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="match_parent"
android:fitsSystemWindows="true">
<FrameLayout
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="@+id/navigation_view"
android:layout_width="320dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="@color/navigation_background_light"
android:overScrollMode="never"
app:headerLayout="@layout/layout_navigation_header"
app:menu="@menu/navigation_main" />
</android.support.v4.widget.DrawerLayout>
复制上去肯定会报错，因为缺少了navigation_main.xml和layout_navigation_header.xml
在res下创建menu文件夹，然后在menu文件下创建navigation_main.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/item_home"
android:checked="true"
android:icon="@drawable/ic_home_black_24dp"
android:title="@string/item_home" />
</group>
<group
android:id="@+id/group_user"
android:checkableBehavior="single">

android:icon="@drawable/ic_star_black_24dp"
android:title="@string/item_favourite" />
<item
