Changing from one view to another view onScroll

I am working a project. I have a a layout with a view at top and a Scrollview at the bottom of the view. Initially the layout will look like this.
After I scroll up the bottom layout. The view should smoothly change the the below view. And if I scroll down the view should come back to its previous layout.
As you can see there is a change in the position and size of the textviews. How can I achieve this ?
Here is the layout:

You can use the Collapsing Toolbar Layout
Example Here and here
Edit: some piece of code
<android.support.design.widget.CoordinatorLayout

<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:contentScrim="?attr/colorPrimary">
<ImageView
android:id="#+id/expandedImage"
android:layout_width="match_parent"
android:layout_height="200dp"
android:src="#drawable/beach_scene"

app:layout_collapseParallaxMultiplier="0.7"
/>
<android.support.v7.widget.Toolbar

android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin" >
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/white"

<TextView

Using a Collapse Tool Bar as João said, your code should be like this
and getting my answer as base from here
<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:clipToPadding="false">
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="210dp"
android:background="#color/WHITE">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:collapsedTitleTextAppearance="#style/TextAppearance.AppCompat.Widget.ActionBar.Title.Inverse"
app:expandedTitleMarginStart="72dp"
app:expandedTitleTextAppearance="#style/TextAppearance.AppCompat.Widget.ActionBar.Title.Inverse"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<Your Content>
<android.support.v7.widget.Toolbar
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="40dp"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<include
layout="#layout/homescreen_scrollview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/layout_header_profile"
android:layout_marginTop="15dp" />
On <Your Content> is the place where you should put your string.
Sorry that I can't help more. Your Cody is a little messy and really hard to understand.
Maybe if you edit leaving only the important codes will help.
But maybe this library can help you.

And Here is the output when i run the above code:
Any ideas?

try add attribute android:fitsSystemWindows="true" in your CoordinatorLayout
<?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:fitsSystemWindows="true"
tools:ignore="RtlHardcoded">
.....

Set android:fitsSystemWindows="true" in CoordinatorLayout, AppBarLayout and CollapsingToolbarLayout to reserve space at top.
If you want the background image starting behind the transparent status bar set android:fitsSystemWindows="true" in the main.imageview.placeholder too.

CollapsibleToolbar not showing completely wrong

I decided I wanted to add a collapsible toolbar to a part of my app today. I followed a guide (as I really knew nothing about collapsible toolbars) and it totally went south. Everything is showing incorrectly. Please excuse my lack of experience with these types of layouts. Thanks in advance you wonderful people of StackOverflow

Here is what it looks like:

Ok, I figured it out. It is because I (stupidly) didn't have the appbar layout as the parent for the collapsing toolbar, instead it was itself. Correct layout looks like:
