Answer 1

The error is pretty much what it says - the ScrollView only can have one child. You have a TextView and a EditText in it. Try to wrap those two in a LinearLayout and the LinearLayout in a ScrollView.

A ScrollView is a FrameLayout, meaning you should place one child in it containing the entire contents to scroll http://developer.android.com/reference/android/widget/ScrollView.html

Answer 2

The Error is saying that you can have only one direct child in the scroll view but you are adding more then one view inside a scrollview what you can do is

<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true"
android:scrollbarStyle="insideInset"
android:scrollbars="vertical" >

   <LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    **<!-- Add here which you want -->**

  </LinearLayout>
</ScrollView>

so your code will be like

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/editScreenLinearLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"

You can not put two saperate view inside a scroll view, you need to add all view inside one view. Use this code, or similar one.

<ScrollView

xmlns:tools="http://schemas.android.com/tools"      android:layout_width="match_parent"
