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
try this:
<android.support.design.widget.CoordinatorLayout
...
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="200dp"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
...
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:titleEnabled="false">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="top"
android:background="?attr/colorPrimary"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<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);

SearchView inside Coordinator layout

How can i achieve following layout design where on scrolling up i just get the view with searchview :
1 ----
2------On Scrolling up :
I've tried putting views at certain places in the layout but searchview always ends up in the top most area instead of below home logo or not even visible.
My current layout without any searchview is :
<?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:background="#CFD8DC"
android:fitsSystemWindows="true"
tools:context="com.example.svatts.my22.ScrollingActivity">
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="#dimen/app_bar_height"
android:fitsSystemWindows="true"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/toolbar_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?android:attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="56dp"
app:layout_collapseMode="pin"
app:popupTheme="#style/AppTheme.PopupOverlay">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_scrolling" />
</android.support.design.widget.CoordinatorLayout>

Change your entire toolbar into the following and mind this line:
app:layout_scrollFlags="scroll|enterAlways|snap"
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways|snap">
Then under your toolbar add your view with tabMode scrollable like this:
<your.search.layout
android:id="#+id/your_search_layout_id"
android:layout_width="match_parent"
android:layout_height="your_height"
app:tabMode="scrollable"/>
And add following layout to your content_scrolling you want to scroll with the tab bar
app:layout_behavior="#string/appbar_scrolling_view_behavior"
Working Example
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
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:layout_scrollFlags="scroll|enterAlways|snap">
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout_main"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="scrollable"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />

You can use NestedScrollView for this purpose along with AppBarLayout. For better compatibility use EditText instead of SearchView.

Tablayout not sticking

I am using toolbar with tablayout. Below is my main xml file
<?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"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:fitsSystemWindows="true"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="#+id/sliding_tabs"
style="#style/MyCustomTabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"
app:tabGravity="fill"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/pager_booking_mng"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
In this current code toolbar is not scrolling. when I scroll the list.
But when I set app:layout_scrollFlags="scroll|enterAlways" in Tablayout tag then both the tablaout and toolbar are scrolling and both are getting outside of the screen.
I want only toolbar to scroll and tablayout should get pinned at top(just like whatsapp).

Give scroll flag for the Tablayout as
app:layout_scrollFlags="scroll|enterAlwaysCollapsed"
Hope this wil work.

Android Toolbar disappear during scrolling with Coordinatorlayout

a strange thing happened when I try to implement the toolbar with the Coordinatorlayout.
everything seems ok when I scroll down and scroll up the toolbar show correctly
however after I scroll down to a certain level the screen became
The XML is below, any idea of it, thanks?
<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.v7.widget.RecyclerView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
/>
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:layout_scrollFlags="scroll|enterAlways"
/>
</android.support.design.widget.AppBarLayout>

Place a blank view below your Toolbar before the AppBarLayout closing statement. It worked for me when I had this problem.
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:layout_scrollFlags="scroll|enterAlways" />
<View
android:id="#+id/appbar_bottom"
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#android:color/transparent"
android:visibility="invisible" />
</android.support.design.widget.AppBarLayout>

Try using app:liftOnScroll="false".
It worked in my case.
