I have a Recyclerview and two other views(ImageView and TextView) above Recyclerview.
I want that initially Recyclerview should stay below ImageView and TextView but when the user scrolls the Recyclerview it should come over the other views.

You can achieve it via collapsing toolbar layout.
below is sample code.

</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView

android:padding="10dp"
android:scrollbars="vertical"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
In your hierarchy, make sure your RecyclerView is placed above the ImageView and Textview. Then you can just add the following properties on your recyclerview in the xml :
android:clipToPadding="false"
android:paddingTop="xxxdp"
The property clipToPadding to false is the key !
If you need a dynamic paddingTop, you can programmatically get the bottom of the view which must be right above the Recyclerview and set it as the paddingTop on your RecyclerView.
Note : Your recyclerview background must be transparent and you have to set à non-transparent background on each of your recyclerview's and it will work.
Here is a quick example with FrameLayout but you can use a ConstraintLayout if you prefer.
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center_horizontal"
android:layout_gravity="center_horizontal"
>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:src="#drawable/ic_launcher_foreground"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="MY TEXT"
/>
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false"
android:paddingTop="200dp"
/>
</FrameLayout>
Edit : Here is the same example with ConstraintLayout
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout 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">
<ImageView
android:id="#+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:src="#drawable/ic_launcher_foreground"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"/>
<TextView
android:id="#+id/textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="MY TEXT"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#id/imageView"/>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false"
android:paddingTop="200dp"/>
</android.support.constraint.ConstraintLayout>
I don't know why do you think that fragment in viewpager can't hold collapsing toolbar. Because it can be done with all answers given above. As none of them mentioned the java code for it let me add one for you.
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapse_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
android:fitsSystemWindows="true">
//your code here
</android.support.design.widget.CollapsingToolbarLayout>
In the java code of your fragment call your collapsing toolbar like this.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_one, container, false);
CollapsingToolbarLayout collapsingToolbarLayout=(CollapsingToolbarLayout)rootView.findViewById(R.id.collapse_toolbar);
return rootView;
}
And you will have your desired behaviour.
EDIT
Adding a demo gif for preview.

I have been using this layout file like this and the view kind of jitters whenever I scroll from the recycler view. This doesnt happen for all the pages but a very few ones. it could be an issue with the lay outing style or could be because of the image being rendered. here is a video link. Thanks.

My Problem: The Content of the included RelativeLayout/RecyclerView does not stop before the buttons displayed at the bottom of the screen (see Fig. 1). Therefore the last Elements inside the RecyclerView are overlapped by the buttons after scrolling (see Fig. 2).

I tried to use a ConstraintLayout, but it broke the AppBar.
Update: Now the included Layout exceeds the top of the AppBarLayout.

Put the and the two Buttons in a ConstraintLayout. Then, give the buttons the right rules so they will stay at the bottom of the layout, and modify the tag to look like this:
<include
android:layout_height="0dp"
android:layout_width="match_parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintBottom_toTopOf="#id/projectOverviewCreateProject"
layout="#layout/content_project_list" />
EDIT:
to solve the issue related to the RecyclerView overlapping the appBar, just add this to your ConstraintLayout:
app:layout_behavior="#string/appbar_scrolling_view_behavior"
My problem is, i want use RecyclerView with CollapsingToolbarLayout. But the issue is CollapsingToolbarLayout not scrolling when RecyclerView scrolling. I cant use Nested Scroll to put RecyclerView, because i want load more data to RecyclerView

You can use like this.
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/myCoordinatorLayout"

android:layout_margin="4dp" />
</LinearLayout>

I'm trying to keep a button fixed at bottom when user's scrolling a RecyclerView. This is what I tried:
<?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"
tools:context=".AddProduct">
<android.support.design.widget.AppBarLayout
android:id="#+id/product_app_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffffff"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/main.collapsing"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:expandedTitleMarginEnd="64dp"
app:expandedTitleMarginStart="48dp"
app:layout_scrollFlags="scroll|enterAlwaysCollapsed">
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="16dp"
android:orientation="vertical">
<TextView
android:id="#+id/tv_name"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="16dp"
android:text="teste"
android:textColor="#161616"
android:textSize="22sp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.v7.widget.RecyclerView
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:id="#+id/rv_test"
android:layout_width="match_parent"
android:layout_height="match_parent"></android.support.v7.widget.RecyclerView>
<Button
android:id="#+id/btn_product_add_product"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginBottom="138dp"
android:background="#color/colorPrimary"
android:text="Test button"
android:textColor="#color/textColorPrimary" />
</RelativeLayout>
</android.support.design.widget.CoordinatorLayout>
And then I used AppBarLayout.OnOffsetChangedListener to adjust button margin according by user scrolling.
It worked, but if user scroll a little fast, it can't adjust the margin very well and the button don't appear to be fixed. It's not reliable.
So, how is the best way to do this?
Maybe you can use a ConstraintLayout instead of your RelativeLayout as below:
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.v7.widget.RecyclerView
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:id="#+id/rv_test"
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toTopOf="#+id/btn_product_add_product"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent" />
<Button
android:id="#+id/btn_product_add_product"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
android:background="#color/colorPrimary"
android:text="Test button"
android:textColor="#color/textColorPrimary" />
</android.support.constraint.ConstraintLayout>
As you can see above, when I scroll from 'Foliage Plants', the CollapsibleToolbar collapses as expected but when I drag from any product image, the page scrolls beneath AppBarLayout. Why is this happening and how to fix this? Ive tried setting VerticalRecyclerView.setNestedScrolling to false but that didn't work.

setNestedScrollingEnabled(false) on inner Horizontal RecyclerView solved this problem for me.
