I tried ScrollView but its giving this error -

ScrollView can host only one direct child

add `android:fillViewport="true"` to Scrollview [Relative Layout in ScrollView](https://stackoverflow.com/questions/18677421/relative-layout-in-scrollview) — Farid Ghoorchian, Jun 25 '17 at 07:00

I've changed some of the values in your layout. But anyway, here's your layout should look like.

<?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"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/colorPrimary"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        app:layout_constraintRight_toRightOf="parent"
        app:title="Add New Business" />

    <ScrollView
        android:layout_width="match_parent"
        android:layout_below="@+id/toolbar"
        android:layout_height="match_parent">

        <RelativeLayout

Put your top level RelativeLayout inside the ScrollView. That way it only has 1 direct child.

Then you did it wrong. If you put the entire relative layout on it, and nothing else, it will work. Or you're altering it in coffee and adding new children there – Gabe Sechan Jun 25 '17 at 06:49
