        app:layout_constraintVertical_bias="0.200">

    </ListView>
</androidx.constraintlayout.widget.ConstraintLayout>

and this is the xml file of the listview

I think this is the code you are wanting.

No need to use scrollview here because ListView itself is scrollable. LinearLayout with Vertical Orientation will solve your issue

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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">

<androidx.appcompat.widget.Toolbar
    android:id="@+id/toolbar2"
    android:layout_width="match_parent"
    android:layout_height="5dp"
    android:background="?attr/colorPrimary"
    android:minHeight="?attr/actionBarSize"
    android:theme="?attr/actionBarTheme"
    tools:layout_editor_absoluteX="9dp"
    tools:layout_editor_absoluteY="2dp" />


<SearchView
    android:id="@+id/Search"
    android:layout_width="match_parent"
    android:layout_height="56dp"
    android:layout_alignParentTop="true"
    android:iconifiedByDefault="false"
    android:queryHint="Search Here"/>

<ListView
    android:id="@+id/Listview"
    android:layout_width="match_parent"
    android:layout_height="300dp"
    android:layout_marginTop="10dp">

</ListView>
</LinearLayout>
