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




<TextView
    android:id="@+id/NotesWelcomeTextView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/NotesWelcomeText" />

</LinearLayout>


<LinearLayout

        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/Delete" />

</LinearLayout>




<LinearLayout
    android:id="@+id/AddItemToListViewLinearLayout"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"

        android:layout_weight="1" >
    </EditText>



    <Button

Make your main layout as scroll layout inside that put the linear layout.

Keep in mind Scroll layout can hold only one type of item...

Once you do this, the whole layout is scroll able up and down or left and right as per your XML config.
