Q:

Fill RelativeLayout parent with LinearLayout child

This seems simple but I've exhausted my Google search patience.
I have a RelativeLayout that has two sub LinearLayouts side-by-side and I want them both to vertically fill the parent, no matter the height of the two LinearLayouts. This is being used as a ListView row and the content under @id/item_left is generally shorter than the one on the right.
The background drawable doesn't fill the entire row.
Any ideas on making both sides fill?
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="fill_parent">
    <LinearLayout android:id="@+id/item_left"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:paddingRight="2dp"
        android:paddingLeft="2dp"
        android:background="@drawable/item_left"
        android:orientation="vertical">
        <TextView android:id="@+id/time"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="@color/item_left_text"
            android:text="" />
    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:background="@color/item_right_background"
        android:layout_toRightOf="@id/item_left">           
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="@color/item_right_text"
            android:text="Row1" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="@color/item_right_text"
            android:text="Row2" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="@color/item_right_text"
            android:text="Row3" />
    </LinearLayout>
</RelativeLayout>

A:

try this code .... sorry but I changed the color to so the impact when you will change the text of first  TextView   
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="fill_parent"
    android:background="#ffffffff" android:weightSum="1">

    <LinearLayout android:id="@+id/item_left"
        android:layout_width="wrap_content" android:layout_height="fill_parent"
        android:paddingRight="2dp" android:paddingLeft="2dp"
        android:background="#ff0000ff" android:orientation="vertical" >
        <TextView android:id="@+id/time" android:layout_width="wrap_content"
            android:layout_height="wrap_content" android:textColor="#ff555555"
            android:text="sdfdsf s ada d a   asd sad sad"  />
    </LinearLayout>

    <LinearLayout android:layout_width="wrap_content"
        android:layout_height="match_parent" android:orientation="vertical"
        android:background="#ffff0000" 
        android:layout_weight="1" >
        <TextView android:layout_width="wrap_content"
            android:layout_height="wrap_content" android:textColor="#ff555555"
            android:text="Row1" />

        <TextView android:layout_width="wrap_content"
            android:layout_height="wrap_content" android:textColor="#ff00ff00"
            android:text="Row2" />

        <TextView android:layout_width="wrap_content"
            android:layout_height="wrap_content" android:textColor="#ff00ff00"
            android:text="Row3" />
    </LinearLayout>

</LinearLayout>
