Extra space between Collapsing Toolbar Title when expanded

I am facing problem for reducing left spaces of the Collapsible Toolbar Layout title. I want to align the title just below of the back button and I am unable to reduce the space. Thanks in advance. Here is the code.
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.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:background="#color/white"
android:fitsSystemWindows="true"

<com.google.android.material.appbar.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="#dimen/scale_140dp"
android:background="#color/white"
android:theme="#style/AppTheme.AppBarOverlay"
app:elevation="#dimen/scale_0dp">
<com.google.android.material.appbar.CollapsingToolbarLayout
android:id="#+id/toolbar_layout"
android:layout_width="match_parent"

app:collapsedTitleGravity="center_horizontal"
app:expandedTitleGravity="bottom"
app:toolbarId="#+id/toolbar">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/white"
app:layout_collapseMode="pin"
app:popupTheme="#style/AppTheme.PopupOverlay">
<TextView
android:id="#+id/tv_back"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="start"
android:background="#drawable/ic_back"
/>
</androidx.appcompat.widget.Toolbar>
</com.google.android.material.appbar.CollapsingToolbarLayout>
</com.google.android.material.appbar.AppBarLayout>
<include
android:id="#+id/content_scrolling"
layout="#layout/menu_content_scrolling" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>

You forget to add app:layout_scrollFlags="scroll|enterAlways" in CollapsingToolbarLayout
& if possible please attach the issue picture because it is easy to understand others

Create CoordinatorLayot with AppBar expand from bottom

How I can make this:
But expand from bottom???
I was try BottomSheetBehavior, but BottomSheet overlays content.

You can try this. It looks like a CollapasingToolbarLayout:
<?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_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/toolbar_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"> // added this
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_scrolling" /> // your content
</android.support.design.widget.CoordinatorLayout>

SearchView inside Coordinator layout

How can i achieve following layout design where on scrolling up i just get the view with searchview :
1 ----
2------On Scrolling up :
I've tried putting views at certain places in the layout but searchview always ends up in the top most area instead of below home logo or not even visible.
My current layout without any searchview is :
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#CFD8DC"
android:fitsSystemWindows="true"
tools:context="com.example.svatts.my22.ScrollingActivity">
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="#dimen/app_bar_height"
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="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?android:attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="56dp"
app:layout_collapseMode="pin"
app:popupTheme="#style/AppTheme.PopupOverlay">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_scrolling" />
</android.support.design.widget.CoordinatorLayout>

Change your entire toolbar into the following and mind this line:
app:layout_scrollFlags="scroll|enterAlways|snap"
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways|snap">
Then under your toolbar add your view with tabMode scrollable like this:
<your.search.layout
android:id="#+id/your_search_layout_id"
android:layout_width="match_parent"
android:layout_height="your_height"
app:tabMode="scrollable"/>
And add following layout to your content_scrolling you want to scroll with the tab bar
app:layout_behavior="#string/appbar_scrolling_view_behavior"
Working Example
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways|snap">
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout_main"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="scrollable"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />

You can use NestedScrollView for this purpose along with AppBarLayout. For better compatibility use EditText instead of SearchView.

Currently getting something like this
Thank you

You have already added app:layout_scrollFlags="scroll|enterAlways" for TabLayout. Do the same for Toolbar. And remove CollapsingToolbarLayout.

Try with adding below line to your Toolbar.
app:layout_collapseMode="pin"
As per mentioned in Collapsing Toolbars section in Android Developer Blog,
use CollapsingToolbarLayout’s app:layout_collapseMode="pin" to ensure that the Toolbar itself remains pinned to the top of the screen while the view collapses.
