pin two elements in Coordinator layout

I am using CoordinatoLayout to try to achieve something like this:
This is my initial view
Scrolled up
I am using Coordinator layout this way but I am a bit confused about it, ¿is it the right way to achieve it? I have tried different ways but I only get one textview pinned on top.

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

android:layout_height="?attr/actionBarSize"
change this line value to your height.

CollapsingToolBarLayout with TabLayout and ViewPager

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".

Android CollapsingToolbarLayout with Toolbar and TabLayout

I'm making an application which uses CollapsingToolbarLayout with Toolbar and TabLayout.
I want to place the TabLayout to below Toolbar when the header is collapsed.
However, When I try to scroll the view, TabLayout overlays the Toolbar like this linked picture:
I want to make it like this linked picture when I scroll:
My code for the layout is below:
<?xml version="1.0" encoding="utf-8"?>

How can I solve this problem?

Try:
<?xml version="1.0" encoding="utf-8"?>
<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_height="wrap_content"
android:fitsSystemWindows="true"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<include
android:id="#+id/header"
layout="#layout/partial_mypage_header"
android:layout_width="match_parent"
app:layout_scrollFlags="scroll|enterAlways"
android:layout_height="#dimen/mypage_header_height" />
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/orange"
android:gravity="top"
android:minHeight="?attr/actionBarSize"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:titleTextColor="#android:color/white">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageButton
android:id="#+id/button_back"
android:layout_width="#dimen/icon_size_medium"
android:layout_height="#dimen/icon_size_large"
android:layout_gravity="center_vertical"
android:background="#android:color/transparent"
android:scaleType="centerCrop"
android:src="#drawable/btn_back" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="#string/mypage_toolbar"
android:textColor="#android:color/white"
android:textSize="#dimen/text_size_medium"
android:textStyle="bold" />
</LinearLayout>
</FrameLayout>
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="#+id/tab"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="bottom"
android:background="#android:color/white"
android:fitsSystemWindows="true"
app:tabIndicatorColor="#color/orange"
app:tabIndicatorHeight="5dp"
app:tabSelectedTextColor="#color/orange"
app:tabTextAppearance="#style/tab_text_appearance"
app:tabTextColor="#android:color/black" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>

I solved this problem by using expedient. I made 2 toolbars including the original one. and I made one of those transparent. then, It looks working fine but I think it is not clear way.
