Android: proper usage of RelativeLayout - android-layout

Question

I will try to represent the desired layout using text:
Stock Name
==========
symbol | score
GOOG | 76
symbol and GOOG should be in a single vertical Linear layout to group them and they should be aligned to the left score and 76 should also be in a a single vertical Linear layout to group them but they should be aligned to the right.
This is my layout. I could achieve it by the way you can see below. Does anyone got an idea what I am doing wrong? (this is only the relevant portion of the layout)
<?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="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="#+id/stock_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="40dp" />
</LinearLayout>
<RelativeLayout
android:id="#+id/relative_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/stock_symbol" />
<TextView
android:id="#+id/stock_symbol"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="30dp" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/stock_score" />
<TextView
android:id="#+id/stock_score"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="30dp" />
</LinearLayout>
</RelativeLayout>
I also tried using android:layout_alignLeft="#+id/relative_layout" and android:layout_alignRight="#+id/relative_layout" inside the LinearLayout but without success.

I found the error thanks to #RobinHood from the chat room "Android-People":
I had to replace the inner LinearLayouts with RelativeLayout and the inner RelariveLayout should change from android:layout_width="fill_parent" to android:layout_width="wrap_content"
