Leave AdView fixed on the top while scrolling the RecyclerView

I have a RecyclerView and above that, there is an AdView. When scrolling the RecyclerView I would like to leave the Adview in a fixed position. How can I do this?
Here's my RecyclerView when I open the app.
After scrolling the RecyclerView
I'm using FrameLayout, by clicking the open fragment menu as below:
frg = (Fragment)
ContainerFragment.newInstance(getString(R.string.DefaultGaleria), getString(R.string.DefaultFrase), getString(R.string.DefaultGif));
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.popBackStackImmediate(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.replace(R.id.container, frg);
transaction.commit();
Here is the layout.

You can do that easily using a RelativeLayout like the following.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false"
android:paddingTop="50dp" />
<com.google.android.gms.ads.AdView
android:id="#+id/adViewMob"
android:layout_width="match_parent"
android:layout_height="50dp"
android:background="#color/transparent"
ads:adSize="SMART_BANNER"
ads:adUnitId="#string/ad_unit_id" />
</RelativeLayout>
This should serve your purpose.

put this code into your xml file..
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.google.android.gms.ads.AdView
android:id="#+id/adViewMob"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/transparent"
ads:adSize="SMART_BANNER"
ads:adUnitId="#string/ad_unit_id" />
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_below="#+id/adViewMob"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>

recycler view on bottom of the screen

I have an RecyclerView that is stuck to the bottom of the screen. I have tried adding constraints but that does not help. If anyone can help it would be appreciated. My code and an image to show whats wrong is below.
RecyclerView stuck at the bottom

Set your LinearLayout height match_parent
Check your toolbar height should be wrap_content
Important: Your RecyclerView item layout'parent element should be wrap_content.
Like
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
>
<!--do it match parent-->
<LinearLayout
android:layout_height="match_parent"
>
<include
/>
<android.support.v7.widget.RecyclerView
/>
</LinearLayout>
<android.support.design.widget.NavigationView
/>
</android.support.v4.widget.DrawerLayout>

Use android:layout_weight="1" to get the empty space for the recycleview
<android.support.v7.widget.RecyclerView
android:id="#+id/my_recycler_view"
android:layout_width="match_parent"
android:layout_height="0dp"
android:scrollbars="vertical"
android:layout_weight="1"/>

Set Layout like this
<?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="match_parent"
android:background="#color/white"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<include layout="#layout/app_bar_map" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:background="#color/white"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="8.5"
android:orientation="vertical">
<android.support.v7.widget.RecyclerView
android:id="#+id/my_recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:background="#color/white"
android:scrollbarSize="0dp"
android:scrollbars="vertical" />
</LinearLayout>
<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_map"
app:menu="#menu/activity_map_drawer" />
</LinearLayout>
</LinearLayout>
Hope this may help you

A really simple solution (if you don't want to debug anymore), try replace your code with
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout

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">
<!-- here is the toolbar -->
<include
layout="#layout/app_bar_map"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<android.support.v7.widget.RecyclerView
android:id="#+id/my_recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"

I tried to use CoordinatorLayout in Activity and Fragment, but it didn't work. Is any way to use CoordinatorLayout with ActionBar in Activity and other views in fragment?

I have Activity with DrawerLayout and Fragments with CoordinatorLayout working just fine (pay attention where fitsSystemWindows attributes are set)
here is activity layout:
<?xml version="1.0" encoding="utf-8"?>

android:fitsSystemWindows="true">
<!-- Framelayout to display Fragments -->

android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:background="#color/color_primary" />
<android.support.design.widget.NavigationView
android:id="#+id/menu_container"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<!-- Listview to display slider menu -->
<ListView

<!-- Картинки - fb, vk, twitter -->
</LinearLayout>

and fragment's xml with coordinator, action button etc:

</android.support.design.widget.CoordinatorLayout>

here is my solution, the activity layout:
<androidx.constraintlayout.widget.ConstraintLayout 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:layout_height="match_parent">
<androidx.coordinatorlayout.widget.CoordinatorLayout

android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toTopOf="#+id/main_bottom_layout">
<com.google.android.material.appbar.AppBarLayout
android:id="#+id/title_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<com.funvideo.videoinspector.photopick.ui.widget.TitleView
android:id="#+id/title_view"
android:layout_width="match_parent"
android:layout_height="#dimen/dimen_title_bar_height"
android:background="#color/simple_title_bg_default_color"
app:layout_scrollFlags="scroll|enterAlways" />
</com.google.android.material.appbar.AppBarLayout>
<FrameLayout
android:id="#+id/main_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
<LinearLayout
android:id="#+id/main_bottom_layout"
android:layout_width="match_parent"
android:layout_height="#dimen/dimen_title_bar_height"
android:background="#color/simple_title_bg_default_color"
android:orientation="horizontal"
android:visibility="gone"
tools:visibility="visible"
app:layout_constraintBottom_toBottomOf="parent">
<TextView
android:id="#+id/txt_preview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginStart="12dp"
android:text="预览"
android:textColor="#color/social_color_4"
android:textSize="16sp" />
</LinearLayout>
<LinearLayout
android:id="#+id/album_list_root"
android:layout_width="match_parent"
android:layout_height="0dp"
android:orientation="vertical"
android:layout_marginTop="#dimen/dimen_title_bar_height"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toTopOf="parent">
<com.funvideo.videoinspector.photopick.ui.widget.AlbumListView

android:layout_width="match_parent"
android:layout_height="500dp"

tools:visibility="visible"
android:visibility="gone" />
<View
android:id="#+id/album_outside"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#99000000"
android:visibility="gone" />
</LinearLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
the main_container is the place where I append my fragment in my activity:
val fragment = YImageMainFragment.newInstance(album)
supportFragmentManager
.beginTransaction()
.replace(R.id.main_container, fragment, YImageMainFragment.TAG)
.commitAllowingStateLoss()
and the layout of fragment is:
<FrameLayout 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">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/main_recyclerview"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<FrameLayout
android:id="#+id/lot_empty_resources"
android:layout_width="250dp"
android:layout_height="wrap_content"
android:background="#drawable/tips_item_bg"
tools:visibility="visible"
android:visibility="gone"
android:layout_gravity="center"
android:padding="20dp">
<LinearLayout
android:id="#+id/lot_go_filechoose"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:visibility="gone"
android:gravity="center_horizontal"
android:orientation="vertical">
<TextView
android:id="#+id/txv_file_choose"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="end"
android:text="还是无法解决？可尝试使用文件浏览方式选取照片或视频～"
android:textColor="#color/color_t1"
android:textSize="13sp" />
<Button
android:id="#+id/btn_go_file_choose"
android:layout_width="162dp"
android:layout_height="36dp"
android:layout_marginTop="16dp"
android:background="#drawable/yellow_button_selector"
style="#style/LegacyButton"
android:textColor="#color/tip_pop_txt_color"
android:textSize="13sp"
android:text="去选取"/>
</LinearLayout>
</FrameLayout>
</FrameLayout>
not extra code needed, it run as my expected, this could be the versions, below are mine:
appcompatVersion=1.3.1
recyclerviewVersion=1.2.1
com.google.android.material:material:1.4.0
