Can't see a TextView in a RelativeLayout

Question

I've made a XML with RelativeLayout with the following code: I can't see the TextView with the id "TV_voucher_number". I've tried maybe making the XML a scrollview, but then I can't see the ListView properly. The code:

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.ManageYourTrip.mytguideapp.Voucher" >

    <LinearLayout
        android:id="@+id/voucherTitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true">
        <TextView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:text="Voucher"
            android:textColor="@color/Black"
            android:textSize="24sp"
            android:textStyle="bold"/>
    </LinearLayout>


        <TextView
            android:id="@+id/TV_Date"
            android:layout_width="wrap_content"

            android:layout_below="@id/voucherTitle"
            android:text="Date: "
            android:textSize="12sp"
            android:textStyle="bold"

Try this:

</RelativeLayout>

Basically you just need to set your listview above bottom_layout and put your bottom_layout to be alightParentBottom. Hope this is what you want;)
