在Appbar下方设置Recyclerview

Question

I want to set an appbar in my activity_main. For some reason, I am not able to set it properly. It is being set below the recycler view.

Here is my activity_main

 <?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" android:layout_width="match_parent" android:layout_height="wrap_content" /> <RelativeLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation = "vertical" android:layout_marginTop="?attr/actionBarSize" tools:context=".MainActivity"> <android.support.v7.widget.RecyclerView android:id="@+id/recyclerview_heritage_sites" android:layout_width="match_parent" android:layout_height="wrap_content" android:scrollbars="vertical"/> </RelativeLayout> </android.support.v4.widget.DrawerLayout> 

Here is my app_bar_main

 <?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" tools:context=".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="@color/colorWhite" app:popupTheme="@style/AppTheme.PopupOverlay" /> </android.support.design.widget.AppBarLayout> </android.support.design.widget.CoordinatorLayout> 

Thank you for your time and help!

You can use LinearLayout :

<?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">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

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

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation = "vertical"
            android:layout_marginTop="?attr/actionBarSize"
            tools:context=".MainActivity">

            <android.support.v7.widget.RecyclerView
                android:id="@+id/recyclerview_heritage_sites"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:scrollbars="vertical"/>

        </RelativeLayout>

    </LinearLayout>

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