How to hide Toolbar and TabLayout

The problem is that ToolBar is hiding, if you swap specifically for it. But if you scroll the contents of the window, the ToolBar remains motionless, but it should be vice versa.
But in general TabLayout should hide, and ToolBar always remain on top.
I do not know how to implement it, help, pls.
P.C. I read this topic - it didn't help
My code:
<android.support.design.widget.CoordinatorLayout 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.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:fitsSystemWindows="true">
<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/MyMaterialTheme" />
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="50dp"
android:background="#color/backTabColor"
app:layout_scrollFlags="scroll|enterAlways"
app:tabTextAppearance="#style/TabLayoutTextAppearance"
/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>

Disable toolbar scrolling when pressing on it

I tried to find someone with the same question but didn't really know what to search for. If someone else finds a simliar question, just let me know!
I've implemented the toolbar from the design library as follows:
<android.support.design.widget.AppBarLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<include layout="#layout/toolbar" />
<android.support.design.widget.TabLayout
android:id="#+id/mainTabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:tabGravity="fill" />
</android.support.design.widget.AppBarLayout>
and the toolbar layout:
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/mainToolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:theme="#style/AppTheme.AppBarOverlay"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/AppTheme.PopupOverlay" />
The AppBarLayout is a direct child to the CoordinatorLayout. Below the AppBar I have a RecyclerView that correctly lets the AppBar collapse when scrolling up.
However I'm able to press directly on the AppBar and then move my finger up and that way the toolbar collapses even though my RecyclerView is completely empty. I can expand it again by scrolling down on the toolbar again. This behavior doesn't happen when scrolling where the RecyclerView is.
I hope my problem is understandable. I'm using version 25.1 of the support library.
Thanks!
Edit: I tried the solutions below. Didn't change anything. Down below I added a video to show what my issue is. So it's really about the situation when the screen is not full (so no elements from the RecyclerView goes off the screen): If that's the case I don't want the Toolbar to hide at all. In other words: Only hide the toolbar if any elements from RecyclerView go off the screen.

If any more code is needed from my side just let know.

Try this

if u want to fixed the toolbar when appbar is scrolled

<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:scrollbars="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
put your toolbar under a CollapsingToolbarLayout and app:titleEnabled="false"
By setting it to false, you'll get the desired behaviour. The title stays fixed at the top of the screen.
you can do it programetically also:
CollapsingToolbarLayout.setTitleEnabled(false);

Currently getting something like this
Thank you

You have already added app:layout_scrollFlags="scroll|enterAlways" for TabLayout. Do the same for Toolbar. And remove CollapsingToolbarLayout.

Try with adding below line to your Toolbar.
app:layout_collapseMode="pin"
As per mentioned in Collapsing Toolbars section in Android Developer Blog,
use CollapsingToolbarLayout’s app:layout_collapseMode="pin" to ensure that the Toolbar itself remains pinned to the top of the screen while the view collapses.

Hiding view below toolbar in coordinator layout

I'm working on creating a layout that works as follows:
Toolbar at the top
Toolbar below top toolbar
RecyclerView
And when I scroll, I want to hide the toolbar in between top toolbar and recyclerView. My Layout is as follows:
<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="SomeActivity">
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
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="wrap_content"
android:elevation="4dp"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
app:popupTheme="#style/AppTheme.PopupOverlay"
app:layout_scrollFlags="scroll|enterAlways"/>
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="50dp"
android:minHeight="0dp"
android:id="#+id/info_bar"
app:popupTheme="#style/AppTheme.PopupOverlay"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
app:layout_scrollFlags="scroll|enterAlways" />
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/content_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
With these changes, both the toolbars become hidden when scrolling.
I just need to hide the second toolbar.
EDIT : If I can't get this to work, I'll be attaching a scroll listener to my recyclerView and resolving this that way. But I was wondering if there is a cleaner solution with scroll behaviors

Moved the top toolbar out of the coordinatorlayout and thus resolved this issue.
(Thanks to a colleague)

android:src="#drawable/ic_done" />
</android.support.design.widget.CoordinatorLayout>

If I understood properly, then you might want to collapse hole collapseableToolbar when it is scrolled up, instead it is showing some (20dp) space between ToolBar and listItem. for me it took half of the day, and problem is just a boolean value in coordinatorLayout. Just change "fitsSystemWindows" value from true to false.
with this you can hide image of the collapseToolBar upon scrolling.
