How to fix button at bottom in android studio with scrollview

When scroll view scrolls I want the button to remain at the bottom like shown in the image. The place order button stays(It is a popup or not). Please help I am new at android. Thanks in advance
Here is the code
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
tools:context=".MainActivity" >
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="10dp"
android:layout_marginBottom="0dp" />
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/search"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true"
android:text="Search" />
</RelativeLayout>

That button should not be part of the ScrollView then. What you need is to put the button in the parent layout, at the same level of your ScrollView. You can use either ConstraintLayout or RelativeLayout.
It would look something like this if you use RelativeLayout:
<RelativeLayout>
<ScrollView>
...
</ScrollView>
<Button
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true
... />
<RelativeLayout>

<androidx.constraintlayout.widget.ConstraintLayout
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">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fillViewport="true"
android:nestedScrollingEnabled="true"
app:layout_constraintTop_toBottomOf="#+id/relMainUnspentTwo">
</ScrollView>
<Button
android:id="#+id/btnContinueUnSpentTwo"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/button"
android:text="#string/conti"
app:layout_constraintBottom_toBottomOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>

Just add android:layout_above="#+id/search" to your recyclerView
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
tools:context=".MainActivity" >
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/search"
android:layout_marginTop="10dp"
android:layout_marginBottom="0dp" />
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/search"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true"
android:text="Search" />
</RelativeLayout>

scrollbar in constraint layout not working

I have tried the below code but it doesn't scroll when I rotate my application it will cover most of screen but I need to scroll there it doesn't working there. Is it right way to use scroll view in constraint layout. I have seen this type of example. There it was in working condition I have tried the below code but it doesn't scroll when I rotate my application it will cover most of screen but I need to scroll there it doesn't working there.

follow this layer it might work.put appbarlayout inside ConstraintLayout layout
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!--add your scrollview or nestedscrollview here-->
</LinearLayout>
</android.support.design.widget.AppBarLayout>

Your ScrollView height is fixed to 611dp.
If you use a fixed size, then the content should be greater than 611dp to be able to scroll.
You should use
<ScrollView
android:id="#+id/scrollView2"
android:layout_width="match_parent"
android:layout_height="match_parent"
....>

FrameLayout after ScrollView allways on bottom

I need to made layout that will contain ScrollView with some dynamic length text and Button in FrameLayout after(below). With long text all is okay, but when text is short button stuck right below bottom of ScrollView text part. I want a FrameLayout in the bottom of the screen when text is short and right below ScrollView text part when text long .
Can it be done?

You can use the android:fillViewport attribute of ScrollView to accomplish this.
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"/>
</FrameLayout>
</LinearLayout>
</ScrollView>
What this does is make it so that, in the case where the contents of the LinearLayout are not large enough to fill the screen, the LinearLayout is stretched to fill the screen anyway. That gives the FrameLayout room to grow (based on its layout_weight attribute), which in turn lets the Button float to the bottom of the screen (because of its layout_gravity attribute).
In cases where the contents of the LinearLayout are larger than the screen, no stretching happens. The button is pushed off-screen, but appears when you scroll down (with no space between it and the text).

You can try this code for your approach:
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

Explaination:
What i did was took FrameLayout containing Button out side of ScrollView so that it can always be at bottom of the Container.

thanks in advance

Do this
1) Change root layout to RelativeLayout
2) Set height of ScrollView to wrap_content
3) Change height of ScrollView child which is LinearLayout to
match_parent
4)add this line to Host activity of that fragment
<activity
android:name="Activity_name"
android:windowSoftInputMode="stateHidden|adjustResize" />
Finally the xml looks like:-
<RelativeLayout 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"

I think you need to get rid of those settings inside the ScrollView attribute.
Basically short it down to
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
Put the rest of the settings inside a RelativeLayout that is included inside the ScrollView like this:
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
======== put all the rest of your settings from scrollvide here =====>
<CONTENT> add here the rest of your code </CONTENT>
</RelativeLayout>
</Scrollview>

scroll views and RecyclerView at same time

want to scroll RecyclerView and views in scroll view, in this code scroll only work on views but not scroll the RecyclerView or scroll hide the RecyclerView.I am using nested scrollview but same not working.

Here is my RecyclerView i include it in main class
<RelativeLayout

android:layout_marginRight="#dimen/_4sdp"
android:layout_marginLeft="#dimen/_4sdp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>

Use should use NestedScrollView instead of ScrollView
And I would also recommend setting
Recyclerview.setNestedScrollingEnabled(false);
