Hello all,

I am trying to layout a Button to the left of a TextView that is centered on the screen. My layout looks like this:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center">

 <TextView  
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="foo"
     android:id="@+id/center"
     />

    <Button android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:text="Left button"
     android:layout_toLeftOf="@id/center" />
</RelativeLayout>

Unfortunately, the button just does not appear. I get the following result:

As you see, the button doesn't show up. It works if I use layout_toRightOf, then the button appears to the right of the TextView, just as expected.

Any ideas what I am doing wrong here?
