"Shrink" CardView while scrolling in another view

Screenshot
As you can see, the layout is a bit too big for the older device. My idea is to shrink the CardView while the user is scrolling in the white area (ViewPager) to make it bigger. I have seen it working well in another app (can't remember which). I have no idea how I can do it, do I need write it programmatically?

It may not be applicable to your current layout but if you can integrate Android's collapsing toolbars you may save youself a bit of time.
Otherwise you could use something like this to detect when the user is at the top of your list and show the view, hiding it otherwise

Try this sample layout, just change the code inside nested scrollview with your tablayout
<android.support.constraint.ConstraintLayout

In recyclerview add an attribute
nestedScrollingEnabled to false in xml it will solve your problem

Avoid scrolling in bottom view inside ViewPager inside CoordinatorLayout

I have this structure in my main layout
<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="wrap_content"
android:fitsSystemWindows="true"
tools:context="com.pingvalue.example.MainActivity">
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
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="wrap_content"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<include
android:id="#+id/linear_header"
layout="#layout/product_detail_header" />
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.CollapsingToolbarLayout>
<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>
and this is my layout that I'm using in a fragment inside ViewPager
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="6dp">
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:drawableRight="#drawable/ic_insert_emoticon_black_24px"
android:gravity="center_vertical"
android:hint="#string/what_do_you_want_to_say"
android:textSize="16sp" />
<Button
android:layout_width="40dp"
android:layout_height="30dp"
android:layout_marginLeft="6dp"
android:background="#drawable/ic_send_selector"
android:enabled="false" />
</LinearLayout>
</LinearLayout>
I want to achieve the following behaviour. This is a screenshot when AppBarLayout is collapsed:
As you can see the layout with the EditText and Button is visible, but when I scroll up it disappears. I've try with a custom CoordinatorLayout behaviour but it doesn't work because it is not a direct child from my CoordinatorLayout. I've try also changing match_parent to wrap_content but it put empty space below the LinearLayout.

Put the LinearLayout with your EditText in it outside of the CoordinatorLayout and wrap everything in a LinearLayout.

This should allow you to have your composer area always visible no matter how far you have scrolled the header.

Try with following layout
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="6dp"
android:layout_weight="0">
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:drawableRight="#drawable/ic_insert_emoticon_black_24px"
android:gravity="center_vertical"
android:hint="#string/what_do_you_want_to_say"
android:textSize="16sp" />
<Button
android:layout_width="40dp"
android:layout_height="30dp"
android:layout_marginLeft="6dp"
android:background="#drawable/ic_send_selector"
android:enabled="false" />
</LinearLayout>
</LinearLayout>

I've tried also adding a NestedScrollView with no result

Testing it on my device i get this
The ViewPager Fragment overlays the TabLayout if it has content and displays the TabLayout on top of the ImageView when there is no content.
What am i doing wrong, i am still somewhat of an Android noob.

CollapsingToolbarLayout needs a minHeight. This tells the parent AppBarLayout how much it can collapse. I assume you want the Toolbar and the TabLayout to stay at the top of the screen (because you are using the exitUntilCollapsed scroll flag). I would make both of those have android:layout_height="?attr/actionBarSize" and use double that value as the minHeight of the CollapsingToolbarLayout.
ViewPager needs app:layout_behavior="#string/appbar_scrolling_view_behavior".

CoordinatorLayout Scrolling and Pinning

I have : There is 1. Toolbar, 2. ViewPager, 3. TabLayout, 4. small ViewPager, 5. ViewPager for Fragment which has RecyclerView :)
Desired: When RecyclerView inside 5. ViewPager at below is scrolled, 1.Toolbar, 3.TabLayout, 4.ViewPager must be pinned and ONLY 2.ViewPager should be scrolled and gone like below:
Problem: I can't only pin 2.ViewPager without pinning 1.Toolbar. So it is like, i pin both 1.Toolbar and 2.ViewPager or none of them.
Question: How to only hide 2.ViewPager when scrolling?

If i underestood that correctly, you can use CollapsingToolbarLayout with this flag:
app:layout_scrollFlags="scroll|exitUntilCollapsed"
Which says:
Scroll the view and after it Collapsed, exit (or your purpose, hide it
after Collapsed).
Here is a good example of how that is working: https://github.com/TheLittleNaruto/SupportDesignExample
Just put your contents into it for after it collapsed, then it will hide or exit that view.i think this is what you were looking for.
EDIT: use it with your own implementation.
Or something like this actually:
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
android:theme="#style/AppTheme">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/toolbar_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbarFeedNew"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<android.support.v4.view.ViewPager
android:id="#+id/viewPagerTopFeedNew"
android:layout_width="match_parent"
android:layout_height="150dp" />
<!--Perhaps a ViewPager-->
</android.support.design.widget.CollapsingToolbarLayout>
<android.support.design.widget.TabLayout
android:id="#+id/tabLayoutFeedNew"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/darker_gray"
app:tabMode="scrollable" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="58dp"
android:background="#null"
android:orientation="vertical">
<android.support.v4.view.ViewPager
android:id="#+id/viewPagerSkorFeedNew"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#null" />
<com.viewpagerindicator.CirclePageIndicator
android:id="#+id/circleIndicatorFeedNew"

android:paddingTop="4dp"

app:pageColor="#bbbbbb"
app:strokeColor="#bbbbbb" />
</LinearLayout>

Hope that helps.
