Android Custom XML layout for SQLite

So I have been working on a project app that reads from a database and prints the contents of the DB into a list view. I now want to print more then just one column, I want to add two buttons and an edittext to the row that is being printed. I have created the new xml file that I want to use but when i try to set the new layout to be this xml file it doesnt work. Can anyone explain or show me how to fix my problem?

This is the XML layout I want to use for each row

<RelativeLayout xmlns:android="http://ift.tt/nIICcg"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">

<TextView android:id="@+id/item1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="30sp"
    android:paddingBottom="5dp"
    android:hint="@string/hint"/>

<Button
    android:id="@+id/plusButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/plusButton"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true" />

<EditText
    android:id="@+id/edit1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:hint="@string/hint"
    android:layout_alignParentTop="true"
    android:layout_toLeftOf="@+id/minusButton"
    android:layout_toStartOf="@+id/minusButton"
    android:layout_marginRight="30dp" />

<Button
    android:id="@+id/minusButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/minusButton"
    android:layout_alignParentTop="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true" />

</RelativeLayout>

And this is the class where I am displaying the contents of the SQLite database, the error occurs on line 100 when i try to change the android.R.layout to the row.xml file
