Android - How to make this parallax animation (see the animation)

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"

RecyclerView does not scroll while searching

I have a recyclerview assoicated with a filtered search in a toolbar. When I start the search, the number of items displayed by the recyclerview is far larger than the screen size. But when I try to scroll up by swiping to look at the elements off the screen, there no response. I thought RecyclerViews like ListViews always support scrolling. Any ideas why my RecyclerView is not scrolling?
Here is the coordinator layout for the tool bar, search, and recycler view that gets included in my main layout (I apologize for the formatting but the insert code widget does not work correctly):

All other aspects appear to be okay. The list interactively responds to user input text and click actions on the recyclerview items are able to obtain the searched-for information. But this list never scrolls. I have tried numerous approaches taking hints from related issues (adding various types of scroll layouts, invoking scroll-related attributes in various places, etc. all within the coordinator layout) but the behavior remains unchanged. There must be something really stupid that I am doing to kill such a basic behavior.

Try moving the RecyclerView outside of the AppBarLayout as follows:
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.lampreynetworks.cpa.CPA_Activity">

android:layout_width="match_parent"
android:layout_height="match_parent">

android:id="#+id/toolbar_search_id"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/colorToolbarBackground"
android:theme="#style/AppThemeDark"
app:contentInsetEnd="0dp"
app:contentInsetStart="0dp">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/card_recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>

change recyclerview height to wrap_content.
<android.support.v7.widget.RecyclerView
android:id="#+id/card_recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
put your recyclerview out of AppBarLayout.

how to put scroll view in collapsing toolbar layout in android?

I want something similar to below asked question where instead of 'view 1' ,it's going to be a scroll view :

Given below xml code is my layout 'activity_sub_card_content1' that i have included in my CollapsingToolbarLayout. i want something similar to this:
How to place a layout below toolbar in collapsing toolbar layout?
but it has a relative layout that is not too long. Mine will be long,so i want to put my layout in scroll view.
The code i have tried shows my scrollview,but it does not scroll it,instead it collapses the toolbar.
<ScrollView android:layout_width="match_parent"

android:layout_margin="20dp"
android:layout_width="match_parent"
android:layout_height="200dp">

</ScrollView>

You could try adding these two lines in your code:
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
>
<Your code here with
app:layout_behavior="#string/appbar_scrolling_view_behavior">
</android.support.v4.widget.NestedScrollView>

Can you try to add this tag
app:layout_behavior="#string/appbar_scrolling_view_behavior"
<ScrollView android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/trial"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
xmlns:android="http://schemas.android.com/apk/res/android">
----- your code
</ScrollView>
AppBarLayout also requires a separate scrolling sibling in order to know when to scroll. The binding is done through the AppBarLayout.ScrollingViewBehavior class, meaning that you should set your scrolling view's behavior to be an instance of AppBarLayout.ScrollingViewBehavior. A string resource containing the full class name is available.

CollapsingToolbarLayout: Fix custom layout on top

here's what I wanna do: I want to display a map in a CollapsingToolbarLayout, below the map should be a custom layout that contains a couple of controls. Below that is a RecyclerView. I want to be able scroll the custom layout as well as the RecyclerView but fix the custom layout at the top while the RecyclerView keeps scrolling.
Here's an image of what I want to achieve (grey = map; red = custom layout; green = RecyclerView):
Here's what I have so far. It works well, except for that the custom layout (red) won't stop scrolling if it reaches the screen's top.

What's the easiest way to achieve this behavior?

The answer is actually pretty simple. I just had to move my custom layout into the AppBarLayout.
Here's the layout:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/appBarLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:fitsSystemWindows="true">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsingToolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<com.mapbox.mapboxsdk.maps.MapView
android:id="#+id/map_view"
android:layout_width="match_parent"
android:layout_height="400dp"
app:layout_collapseMode="parallax"
mapbox:zoom="12"
mapbox:style_url="#string/style_light"
mapbox:access_token="#string/access_token">
</com.mapbox.mapboxsdk.maps.MapView>
</android.support.design.widget.CollapsingToolbarLayout>
<include layout="#layout/current_activity"
android:layout_width="match_parent"
android:layout_height="48dp"
android:background="?attr/colorAccent"/>
</android.support.design.widget.AppBarLayout>
<LinearLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.v7.widget.RecyclerView
android:id="#+id/activity_list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="16dp">
</android.support.v7.widget.RecyclerView>
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>

Add app:layout_collapseMode="pin" this attribute in your red view to pin at the top of the screen.
This may fix your issue

CoordinatorLayout with RecyclerView And Collapsing header

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.
