我如何在工具栏后面设置导航抽屉

Question

我试图将Navigation drawer设置为Toolbar，我已经尝试过设置 android:layout_marginTop="@dimen/abc_action_bar_default_height_material"到NanvigationView，但没有任何变化，我也遵循此Navigation Drawer Below Toolbar但不起作用

activity_main.xml：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/top_parent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".MainActivity">
<include
    layout="@layout/app_bar_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
<android.support.v4.widget.DrawerLayout
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<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="false"
    android:theme="@style/NavigationView"
    android:background="#2b2b2b"
    app:itemTextColor="#FFF"
    app:menu="@menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
</RelativeLayout>

App_bar_main.xml：

<?xml version="1.0" encoding="utf-8"?>
 <android.support.design.widget.CoordinatorLayout    
 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:layout_width="match_parent"
 android:layout_height="match_parent"
 android:fitsSystemWindows="true"
 tools:context="maa.a4kandhdwallpapers.MainActivity">
 <android.support.design.widget.AppBarLayout
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
      android:theme="@style/AppTheme.AppBarOverlay">
    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay" />
  </android.support.design.widget.AppBarLayout>
    <include layout="@layout/content_main" />
</android.support.design.widget.CoordinatorLayout>

尝试使用activity_main.xml的下一个代码：

<?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:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:openDrawer="start">

<include
    layout="@layout/app_bar_main"
    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:theme="@style/NavigationView"
android:background="#2b2b2b"
app:itemTextColor="#FFF"
app:menu="@menu/activity_main_drawer" 
android:layout_marginTop="@dimen/appbar_height"/>

appbar_height - 你在dimen.xml中的值。它可以等于?actionBarSize。
