My layout results in the error "ScrollView can host only one direct child" when using RelativeLayout.

I want to add a scroll view after a toolbar. Everything inside the ScrollView should be scrollable vertically, but when I try this code, it results in the aforementioned error "ScrollView can host only one direct child with relativelayout".

The Layout.xml file:

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

    //Scroll view starts here 
        <include
            android:id="@+id/toolbar"
            layout="@layout/view_toolbar" />

        <ScrollView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:scrollbars="vertical">

        <RelativeLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@color/grey_868686">

            <TextView

take a relative layout or linear layout then put all view into it and then wrap this relative layout with scroll view your problem will be solved.

The Answer given by Md.ibrahim khalil is absolutely right,

Try by replacing your layout with this,

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    //Scroll view starts here

    <include
        android:id="@+id/toolbar"
        layout="@layout/view_toolbar" />

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:scrollbars="vertical">

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content">

            <RelativeLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:background="@color/grey_868686">

                <TextView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_centerVertical="true"
                    android:gravity="center_vertical"
                    android:paddingLeft="8dp"
                    android:paddingRight="8dp"
                    android:text="Most Download"
                    android:textColor="@color/white"
