I've a big doubt, how can I make this animation (see it below) in the Android?
What I've tried before?

But the layout breaks, because the second Toolbar, appears with a large text, and it gets over my Header at the moment it's scrolled, and even then, when I do the scroll effect on the page, it looks like I've been placed all within a ScrollView and not with an effect and delay as it appears in the image above.
NOTE: The scroll does not have the effect of "locking" the button
as it is in a time of the image shown, is that I re-animated the
animation to show and I'm not that good, so the scroll happens
naturally, but with delay in this piece that "lock"

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: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.

I want the toolbar to only show when the user reaches the far top of the view. I have a recyclerview that has a lot of rows. I want the user to be able to go up and down without being bothered by the toolbar unless he reaches the very top of the view. How can this be done? Thanks.
Edit: edited the code.
in content_main.XML use android.support.v4.widget.NestedScrollView instead of ScrollView.
also use app:layout_behavior="#string/appbar_scrolling_view_behavior" inside android.support.v4.widget.NestedScrollView like below.
<android.support.v4.widget.NestedScrollView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="#+id/textone"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="hello world"
android:textSize="25dp"
android:textStyle="bold" />
/// Add your other code here
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
reference from hear : How to hide ToolBar when i scrolling content up in android
I'm working on android application just for learning purposes an in the app I have a Relative layout who has another linear layout in it and a RecyclerView. The RecyclerView is there to show a list of friends for the particular user and the Linear layout is to give an option to the user to click on it and to be redirected to another activity where he can add new friends. This is the .xml file.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/addFriendLayout">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/add_new_friend"
android:gravity="center"
android:textSize="24sp"
android:textStyle="bold"
android:layout_margin="16dp"
android:textColor="#color/addNewFriendTextColor"/>
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/friendsRecyclerView"
android:layout_below="#+id/addFriendLayout"/>
</RelativeLayout>
What I want to do?
-When the user scroll up I want that Linear layout to hide behind the toolbar and then when user scroll down to collapse and become visible.
This is one similar case like mine but I didn't understand how to do it.

I've found strange behavior in RecyclerView with CollapsingToolbarLayout.
When I scroll RecyclerView - it works perfectly. But when I try to fling it and stop that fling fast enough - I can see, that RecyclerView is scrolled "inside itself".
Bad fling behavior:
RecyclerView should not be scrollable before CollapsingToolbarLayout fully collapses, but it is (in normall scroll everything works perfectly, problem only appears when flinging).
My layout looks like this:
<android.support.design.widget.CoordinatorLayout

Here are sources and two videos that show what I mean:
https://NonGrate#bitbucket.org/NonGrate/collapsingtoolbarlayout-recyclerview-bug.git
I have a layout like the following:
(Toolbar,
Header View, Text View, RecyclerView)
I need the header to be collapsed when I scrolling recyclerview's items.
So that the view "Choose item" and recyclerview left on the screen.
I saw examples when toolbar is being collapsed, but I need toolbar to be present always.
Which layouts/behavior should I use to get this work?
You can achieve it by having this layout:
<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.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<!-- HEADER -->
<RelativeLayout
...
app:layout_collapseMode="parallax">
.....
</RelativeLayout>
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
<!-- IF YOU WANT TO KEEP "Choose Item" always on top of the RecyclerView, put this TextView here
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:text="choose item" />
-->
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
You pin your toolbar by having the app:layout_collapseMode="pin" property set. You make RecyclerView properly scrollable by setting app:layout_behavior="#string/appbar_scrolling_view_behavior" and that's pretty much it.
NB! Position of "Choose item" TextView depends on the particular behaviour you want to achieve:
you can include it as a first element of your RecyclerView's Adapter to scroll it away, once user start scrolling through the RecyclerView;
you can add it into AppBarLayout so it will always stick on top of the RecyclerView, whenever you scroll it or not;
You can read more here Android Design Support Library and here Design Support Library (III): Coordinator Layout
I hope, it helps!
The below code is working but not smooth scroll compare reqular recyclerview I thought.
