You haven't added weightSum and orientation values ​​for LinearLayout.
Source

You can use a NestedScrollView instead of the ScrollView. And also put your RecyclerView as well as the LinearLayout inside the NestedScrollView. And enable android:nestedScrollingEnabled=true. Should work for you.
<NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:nestedScrollingEnabled=true>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recyleview"
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintBottom_toTopOf="#id/linearlayoutorder"
app:layout_constraintTop_toBottomOf="#id/relative" />
<LinearLayout
android:id="#+id/linearlayoutorder"
android:layout_width="match_parent"
android:layout_height="100dp"
android:background="#000000"
android:backgroundTintMode="#color/colorPrimary"
android:orientation="horizontal"
android:weightSum="2"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="1"
android:text="TOTAL" />
<TextView
android:id="#+id/totalidcost"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right|center"
android:layout_weight="1"
android:textAlignment="textEnd"
tools:ignore="RtlCompat" />
</LinearLayout>
</LinearLayout>
And in your java class where you have your recyclerview set recyclerView.setNestedScrollingEnabled(true or false);

Use ConstraintLayout like this way, Here is full xml code what you need
<?xml version="1.0" encoding="utf-8"?>

run below code for each of your RecyclerView within your NestedScrollView
ViewCompat.setNestedScrollingEnabled(recyclerView, false);

Try this code, it works well,
rvCompanies.setHasFixedSize(true);
LinearLayoutManager layoutManager = new LinearLayoutManager(getApplicationContext());
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
rvCompanies.setLayoutManager(layoutManager);
rvCompanies.setNestedScrollingEnabled(false); // important

BottomNavigationView doest not shown currectly

I'm adding a BottomNavigationView to My MainActivity
at first show nothing wrong but after click on other items, BottomNavigationView strangely moving up and down. In other projects, I had never this problem and I don't know why I am getting this:
p.s: In default fragment (which is first at right in screenshot) I have a content but in other fragments, I have no content.
Here is my MainActivity 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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.activity.MainActivity">
<FrameLayout
android:id="#+id/MainActivity_FrameLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/MainActivity_BottomView" />

app:elevation="2dp"
app:itemTextColor="#android:color/white"
app:itemIconTint="#android:color/white"

and here is the screenshot of how does shown
after clicking on another item
and when select default item again

Thanks in advance for your guidance.

Change your root layout to LinearLayout like below:

Scrollview contains viewpager and one linearlayout

I tried to make a scrollable view with one ViewPager which will take 90% of the screen and then some useful information about images inside the ViewPager.
However, when I add the ScrollView widget, all sizes and weight doesn't work even if I set android:fillViewport="true". Here's my layout.
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView
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="wrap_content"
android:fillViewport="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:weightSum="100"
android:scrollbars="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/background_light"
android:elevation="0dp"
android:minHeight="?attr/actionBarSize"
android:theme="?attr/actionBarTheme"
app:popupTheme="?android:attr/homeAsUpIndicator" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="90"
android:orientation="vertical"
android:padding="50dip">
<android.support.v4.view.ViewPager
android:id="#+id/product_sheet_viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
<TextView
android:id="#+id/product_sheet_description"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="bbb"/>
<TextView
android:id="#+id/product_sheet_color"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Color: Yellow" />
<TextView
android:id="#+id/product_sheet_reference"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Ref: 2049/889/300" />
</LinearLayout>
</android.support.v4.widget.NestedScrollView>

Remove the android:fillViewport="true" and set the layout_height of your NestedScrollView to match_parent.
So here's the final layout should look like.
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView

android:minHeight="?attr/actionBarSize"

app:popupTheme="?android:attr/homeAsUpIndicator" />
<LinearLayout

It is displaying bottom card view items and toolbar. But not displaying recyclerView Items. items are available in recyclerView, But i am missing something in layout file (display part)
Can anyone help me what i am missing here?

You have not set layout_below property in cardview. That is why your recyclerview is overlapped by cardview
<?xml version="1.0" encoding="utf-8"?>
