Scrollview overlapping on fragments

The following is my activity_scrolling.xml
<?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:fitsSystemWindows="true"
tools:context=".ScrollingActivity">

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">
<com.google.android.material.appbar.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|exitUntilCollapsed"
app:toolbarId="#+id/toolbar">
<androidx.appcompat.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" />
</com.google.android.material.appbar.CollapsingToolbarLayout>
</com.google.android.material.appbar.AppBarLayout>
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="300dp"
android:fitsSystemWindows="true"
tools:context="com.example.visualcovid_19.ScrollingActivity"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
<include layout="#layout/content_scrolling" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
The following is my content_scrolling.xml
<?xml version="1.0" encoding="utf-8"?>
<ScrollView 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:orientation="vertical"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context=".ScrollingActivity"
tools:showIn="#layout/activity_scrolling">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<include
layout="#layout/country_card_fragment"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<include
layout="#layout/country_card_fragment"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</ScrollView>
But, I end up getting the scroll view overlapped on map fragment and right below AppBarLayout
a screenshot is attached below.
I want the scroll view to start at the end of the map fragment and the initial scroll should take the AppBarLayout and the fragment below it to the top as usual and the rest scroll view should be able to scroll.

Try to remove tools:showIn="#layout/activity_scrolling" from content_scrolling.xml. Also, try to not include your cards, use the full code.

Placing layout below AppBarLayout

I have currently this layout set
<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"
tools:context="com.beastovest.copilot.activity.MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:background="#android:color/transparent"
app:elevation="0dp"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="#style/AppTheme.PopupOverlay"/>
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?attr/actionBarSize"/>
</android.support.design.widget.CoordinatorLayout>
And it looks like
this
by removing:
android:layout_marginTop="?attr/actionBarSize"
it stars to look like this
The button is still clickable however it is not visible.
I am trying to achieve this look
The action bar to be in front of all content

A guy posted a solution which was to replace the CoordinatorLayout with Relative layout and it worked.
Result
<?xml version="1.0" encoding="utf-8"?>

I just want to make my Toolbar static how can I achieve Thanks in advance!!

Remove app:layout_scrollFlags="scroll|enterAlways" this from Toolbar and check scroll.

Okay there are lot of answers but ,
Is this what are you looking for?
If yes, you can use CollapsingToolbarLayout
For the second view here is my xml all you need to remove ImageView to get the first view.
<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:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="#+id/profile_id"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/monkey"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin" />
</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="#ffe5e5e5"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include layout="#layout/activity_second" />
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
</android.support.design.widget.CoordinatorLayout>
Take a note that I've used app:layout_collapseMode="pin" for Toolbar
Have fun ^_^

Make your layout like this. Your toolbar will be fixed at top while you scroll your layout.
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:fitsSystemWindows="true"
>
<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|enterAlwaysCollapsed"
app:statusBarScrim="#color/primary"
app:contentScrim="#color/primary"
app:titleEnabled="false"
app:layout_collapseMode="none"
android:fitsSystemWindows="true">
<!--
we must create the value entry for the toolbar height here as different version would have different heights
-->
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:gravity="top"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"

How to scroll and collapse a LinearLayout with Toolbar in Coordinator Layout

I'm trying to accomplish a scrolling behavior with coordinator layout in my application.
I've the following layout structure for the activity.
<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:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.Dark.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"
app:popupTheme="#style/AppTheme.Dark.PopupOverlay"/>
</android.support.design.widget.AppBarLayout>
<!-- The layout to be collapse with toolbar -->
<LinearLayout
android:id="#+id/ll_collapse_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/rv_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>
When I scroll up the recycler view items the toolbar collapses and goes up out of the window and when I scroll down I get the toolbar back.
Is it possible to collapse the LinearLayout with toolbar when I scroll the Recycler View?

How to use scrollbar and fast Scroll to NestedScrollView

I'm using NestedScrollView with Coordinator layout.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"

<android.support.design.widget.CoordinatorLayout
android:id="#+id/coordinator_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<...AppBarLayout
android:id="#+id/appBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:toolbarId="#+id/toolbar"
app:contentScrim="#color/my_primary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<include
layout="#layout/calendar_view"/>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
</...AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:id="#+id/nestedScrollView"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<FrameLayout
android:id="#+id/frame_layout_2"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</android.support.v4.widget.NestedScrollView>
</android.support.design.widget.CoordinatorLayout>
</RelativeLayout>
I want to add a scroll bar to drag the scroll view using it (Fast Scroll). It looks like NestedScrollView doesn't have fastScroll attribute.
I tried adding
android:scrollbars="vertical"
android:fadeScrollbars="false"
android:fastScrollEnabled="true"
android:fastScrollAlwaysVisible="true"
All of this didn't Work.
