CollapsingToolbarLayout with two views, make one scroll but not the other

I have an activity with a toolbar and a recyclerview. On top of the recyclerview I have a panel that I want to be scrollable (to move along with the scroll of the recyclerview).
I want this panel to scroll behind the toolbar, so when the scrolling happens, the toolbar stays in place and the panel slides behind it.
Kind of what they do here:

But I cant find the right combination of options with CollapsingToolbarLayout to achieve this effect:
<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:gravity="center_horizontal"
android:orientation="vertical"
tools:context=".ui.profile.ProfileActivity">
<android.support.design.widget.AppBarLayout
android:id="#+id/profile_appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/topbar_gradient"
android:theme="#style/AppTheme.Dark">
<android.support.design.widget.CollapsingToolbarLayout
android:orientation="vertical"
android:id="#+id/detail_collapsing"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:background="#drawable/topbar_gradient"
app:layout_collapseMode="none"
android:minHeight="?android:attr/actionBarSize" />
<LinearLayout
android:layout_marginTop="?actionBarSize"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_collapseMode="none"
app:layout_collapseParallaxMultiplier="0.5">
...
</LinearLayout>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
(...)
</FrameLayout>
</android.support.design.widget.CoordinatorLayout>
To simplify, I've changed the structure to this:
<android.support.design.widget.CollapsingToolbarLayout
android:orientation="vertical"
android:id="#+id/detail_collapsing"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:contentScrim="?colorPrimary"
android:fitsSystemWindows="true"
app:layout_scrollFlags="scroll|enterAlways">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:background="#drawable/topbar_gradient"
app:layout_collapseMode="pin"
android:minHeight="?android:attr/actionBarSize" />
<LinearLayout
android:layout_marginTop="?actionBarSize"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_collapseMode="parallax"
app:layout_collapseParallaxMultiplier="0.5">
<ImageView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:src="#drawable/bar"/>
</LinearLayout>
</android.support.design.widget.CollapsingToolbarLayout>

It does exactly the same when we add an ImageView inside the CollapsingToolbarLayout like this with parallax flag of app:layout_collapseMode:
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:expandedTitleMarginEnd="64dp"
app:expandedTitleMarginStart="48dp"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_scrollFlags="pin" />
<ImageView
android:src="#drawable/cheese_1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax" //Here is the solution
android:minHeight="100dp" />
</android.support.design.widget.CollapsingToolbarLayout>
So you may want to add :
app:layout_collapseMode="parallax"
To your view (LinearLayout) or anything inside.
Read: https://guides.codepath.com/android/handling-scrolls-with-coordinatorlayout#creating-parallax-animations

I solved this problem by moving Toolbar outside of AppBarLayout. Then in code setup Toolbar as SupportActionBar.
<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:gravity="center_horizontal"
android:orientation="vertical"
tools:context=".ui.profile.ProfileActivity">
<android.support.design.widget.AppBarLayout
android:id="#+id/profile_appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/topbar_gradient"
android:theme="#style/AppTheme.Dark">
<android.support.design.widget.CollapsingToolbarLayout
android:orientation="vertical"
android:id="#+id/detail_collapsing"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:layout_scrollFlags="scroll|enterAlways">
<LinearLayout
android:layout_marginTop="?actionBarSize"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_collapseMode="pin">
...
</LinearLayout>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
(...)
</FrameLayout>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:background="#drawable/topbar_gradient"
android:minHeight="?android:attr/actionBarSize" />
</android.support.design.widget.CoordinatorLayout>

You need to change this to get desired effect:
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/detail_collapsing"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical"
app:contentScrim="?colorPrimary"
app:layout_scrollFlags="scroll|enterAlwaysCollapsed|exitUntilCollapsed"
app:titleEnabled="false">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="?actionBarSize"
android:orientation="vertical"
app:layout_collapseMode="parallax"
app:layout_collapseParallaxMultiplier="0.5">
<ImageView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:src="#drawable/bar" />
</LinearLayout>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:background="#drawable/topbar_gradient"
android:minHeight="?android:attr/actionBarSize"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
Your change was in CollapsingToolbar, by using these three attributes "scroll|enterAlwaysCollapsed|exitUntilCollapsed" together will change that effect.
Description :
app:layout_collapseMode="" is attribute used to collapse/pin child views of CollapsingToolbarLayout.
There are three attributes to this :
none : No effects at all.
pin : Pin that view at CollapsingToolbar when scrolled.
parallax : Hide view parallel with CollapsingToolbar hiding.
so if you're having Toolbar pinned to CollapsingToolbarLayout then add this property pin (which will pin it to Collapsing toolbar when scrolled) and parallax will animate it until collapsed.
Let's see
How does scrolling actually works using these 4 attributes in
app:layout_scrollFlags=""
scroll : The view will be scroll in direct relation to scroll
events.(Necessary, otherwise any other attribute won't work)
enterAlways : When entering (scrolling on screen) the view will
scroll on any downwards scroll event, regardless of whether the
scrolling view is also scrolling.
enterAlwaysCollapsed : An additional flag for 'enterAlways' which
modifies the returning view to only initially scroll back to it's
collapsed height.
exitUntilCollapsed : When exiting (scrolling off screen) the view
will be scrolled until it is 'collapsed'.
snap : Upon a scroll ending, if the view is only partially visible
then it will be snapped and scrolled to it's closest edge.

TabLayout disappearing behind ViewPager in CollapsingToolBar

Im trying to create an AppBarLayout using the CollapsingToolBar which contains a Toolbar and a TabLayout and im also using the app:behavior_overlapTop attribute on my RelativeLayout which includes a ViewPager. The problem is that when the CollapsingToolBar is expanded my TabLayout disappears behind the ViewPager as the TabLayout is given a layout_gravity = bottom and due to the fact that i have used app:behavior_overlapTop on my RelativeLayout which includes the ViewPager. How can i fix this ? Thanx in advance.
( This is my first question here, sorry if have missed anything, i would have included images for better understanding of the problem but i dont have enough repo )

CollapsingToolbarLayout center TextView in Toolbar

I want toolbar_title layout center in toolbar, but itlooks like there is some margin on left, if I remove CollapsingToolbarLayout it is ok.
Inorder to center toolbar_title text I set toolbar_title's margin right manualy in code, but the only after the fragment resumed I toolbar_title.getX() can get the correct value, so I postDelayed 50 ms to do this.
now ther is the question:
how to center toolbar_title in CoordinatorLayout on a better way?

You just need to add below attributes in your Toolbar.
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
See similar thread on stackoverflow: Android API 21 Toolbar Padding
See title textview position before and after attributes adding in toolbar.
Before adding attributes:
After adding attributes:

AppBarLayout take space after setVisibility(View.GONE)

I want to hide my AppBarLayout for adding a view dynamically which will take the height of the screen.
For this, i want to remove a view temporaly by setting the visibility of my AppBarLayout to GONE.
The view is not visible, but take space in the screen(half of the height of screen).
My XML code :

Your problem is caused by this line
app:layout_behavior="#string/appbar_scrolling_view_behavior"
You will have to set it programatically on CoordinatorLayout not the actual container fragment that has that field.
Here is how
mContainer = (FrameLayout) findViewById(R.id.main_content_container);
CoordinatorLayout.LayoutParams params =
(CoordinatorLayout.LayoutParams) mContainer.getLayoutParams();
params.setBehavior(null);
mContainer.requestLayout();
If you want to make it scrolling again
params.setBehavior(new AppBarLayout.ScrollingViewBehavior());

Try to set AppBarLayout's height to zero
AppBarLayout appBar=(AppBarLayout)findViewById(R.id.fProfilAppBar);
LinearLayout.LayoutParams params=appBar.getLayoutParams();
params.height=0;
appBar.setLayoutParams(params);

I was able to solve this by moving everything from CollapsingToolbarLayout (CTL) into Toolbar, making Toolbar the only desdendant of CTL. Then I set the CTL's height to wrap_content and in the code I used toolbar.setVisibility(View.GONE). Note that you might want to change the layout inside Toolbar, add some wrapper around its childs, like RelativeLayout or something else.

I have tried these, still not working. better solution is show and hide the CollapsingToolbar and set the AppBarLayout params dynamically.
Do this when ever you show/hide the CollapsingToolbarLayout
mAppBar.setLayoutParams(**new CoordinatorLayout.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT)**);

I have implemented CollapsibleToolbarLayout as below.

I add the image view in a framelayout in the toolbar so that i can have a overlay on the image and a gradient to make the toolbar text visible on some images
But this color line is coming just below the image (see screenshot) on adding the framelayout. If I remove the line
android:fitsSystemWindows="true"
from appbarlayout then the the color line disapperas but toolbar also scrolls away from the view...
Also to show the back button on the toolbar I have added the below code in OnCreate still it does not show
toolbar = FindViewById<Android.Support.V7.Widget.Toolbar>(Resource.Id.anim_toolbar);
SetSupportActionBar(toolbar);
SupportActionBar.SetDisplayHomeAsUpEnabled(true);
SupportActionBar.SetHomeButtonEnabled(true);
SupportActionBar.Title = content.Title;
toolbar.SetNavigationIcon(Resource.Drawable.ic_action);
collapsingToolbar = FindViewById<CollapsingToolbarLayout>(Resource.Id.collapsing_toolbar);
collapsingToolbar.SetTitle(content.Title);
Thanks...

OK got it now had to remove
android:fitsSystemWindows="true"
from
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"

everything good now
Thanks

Consider adding a fixed width to your app bar layout
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="300dp"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:fitsSystemWindows="true">
