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

<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);

Toolbar covers page when clicked

My Activity is built on layout android.support.design.widget.CoordinatorLayout which contains toolbar. In the activity i have three webview which loads google.com, as soon i click the search-bar(to input the keyboards), toolbar extends itself to search-bar, but as soon as i click back key(which removes the cursor from the search bar), toolbar goes to normal size.
Here is my layout:
<android.support.design.widget.CoordinatorLayout
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/coordinatorLayout"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true">
<android.support.v7.widget.Toolbar
android:id="#+id/tool_bar"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:background="#color/ColorPrimary"
android:elevation="2dp"
android:theme="#style/Base.ThemeOverlay.AppCompat.Dark"
android:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:layout_scrollFlags="scroll|enterAlways"
android:fitsSystemWindows="true" />
<com.taadu.slidechat.adaptor.SlidingTabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/ColorPrimary"
android:layout_below="#+id/tool_bar"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:layout_below="#+id/tabs">
</android.support.v4.view.ViewPager>
</android.support.design.widget.CoordinatorLayout>
I have tried to define some numbers in android:layout_height of AppBarLayout but this makes my tabs go away, but then also toolbar size is not normal, it is always short of it's regular height.
I have searched whole stackoverflow, but couldn't find any relevant data.

Your question is a bit unclear... But if I got it correctly, try to set your layout_height to ?attr/actionBarSize.
Your layout will look like this:
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true">
<android.support.v7.widget.Toolbar
android:id="#+id/tool_bar"
android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent"
android:background="#color/ColorPrimary"
android:elevation="2dp"
android:theme="#style/Base.ThemeOverlay.AppCompat.Dark"
android:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:layout_scrollFlags="scroll|enterAlways"
android:fitsSystemWindows="true" />
<com.taadu.slidechat.adaptor.SlidingTabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/ColorPrimary"
android:layout_below="#+id/tool_bar"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
</android.support.v4.view.ViewPager>
</android.support.design.widget.CoordinatorLayout>

SetFitsSystemWindow programmatically doesn't work as expected

I'm trying to work with different AppBarLayouts in one Activity.
When a Fragment is loaded, it can call a "ToolbarManager", that handles the replacing of the currently active Toolbar (namely an AppBarLayout).
For some of these Toolbars (using CollapsingToolbarLayout) I want them to draw behind the StatusBar.
This works fine when setting the "fitsSystemWindow" to true in the XML.
But when using just a Toolbar with layout_scrollFlags="scroll", the Toolbar Title is displayed even behind the StatusBar.
To avoid this, I want to disable the "fitsSystemWindow" when loading such a Toolbar by using setFitsSystemWindow(false).
Disabling works fine, but when re-enabling by setFitsSystemWindow(true) for using with CollapsingToolbarLayout, the StatusBar is colored and the Toolbar is placed below the StatusBar with a padding in size of the StatusBar on top.
Image: Drawn below StatusBar instead of behind
When I don't use setFitsSystemWindow(true) and just set it to true in the XML layout, the display of CollapsingToolbarLayout is fine.
Is this a bug in setFitSystemWindow or is this method just different from the XML attribute?
Here are the layouts I use:
Activity:
<android.support.v4.widget.DrawerLayout 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_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/drawer_layout"
android:fitsSystemWindows="true"
tools:context=".activities.MainActivity"
style="#style/AppTheme">
<android.support.design.widget.CoordinatorLayout
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:fitsSystemWindows="true"
android:id="#+id/coordinator_layout">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:fitsSystemWindows="true"
android:layout_height="wrap_content">
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/fragment_container"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
</FrameLayout>
<ProgressBar
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:indeterminate="true"
android:indeterminateDuration="1000"
android:layout_marginBottom="-7dp"
android:id="#+id/loadingBar"
style="#style/Widget.AppCompat.ProgressBar.Horizontal"
android:layout_gravity="center_horizontal|bottom"
android:gravity="bottom"/>
</android.support.design.widget.CoordinatorLayout>
<include layout="#layout/include_navigationview" />
The AppBarLayout is replaced every time a new Fragment is loaded.
The following layout is the Toolbar which should not draw behind the StatusBar, but the Toolbar should scroll (leaving only the TabLayout visible)
<android.support.design.widget.AppBarLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:id="#+id/toolbar_discover"
android:fitsSystemWindows="true"
android:paddingBottom="0dp">
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:id="#+id/toolbar"
android:layout_height="?attr/actionBarSize"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:theme="#style/AppTheme.Toolbar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:layout_scrollFlags="scroll|snap">
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="#+id/tablayout_discover"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
app:tabMode="fixed"
app:tabGravity="fill" />
</android.support.design.widget.AppBarLayout>
This used to work when I set fitsSystemWindows=false on the CoordinatorLayout in the MainActivity Layout. When doing so, the following CollapsingToolbar cannot draw behind the StatusBar.
<android.support.design.widget.AppBarLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"

Recyclerview + viewpager, make toolbar collapse

I have a recyclerview inside a viewpager. I also have Tabs above that and a toolbar. I'd like to collapse those (or one of those I have to try it out) when I move the recyclerView down. Basically the same as here.
I'm having trouble to get this to work.
Here is what I have:
<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="com.cedric.testdesign.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.TabLayout
android:id="#+id/tabs"
style="#style/MyCustomTabLayout"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"/>
</android.support.design.widget.AppBarLayout>
<com.signpetitions.cedric.signpetitions.components.MyFab
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:src="#android:drawable/ic_dialog_email" />
<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>
Inside the viewPager I have a fragment with a recycler view:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.RecyclerView
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/recyclerView"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />

I added this to the toolbar :
app:layout_scrollFlags="scroll|enterAlways"
Then it works. The issue though is that when the statusbar is transparent the text behind the toolbar is visible. So the statusbar has to have a color.

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.
