Android button layout - get two buttons side-by-side across entire screen

Question

I have two buttons which I would like to appear side-by-side horizontally, but together they fill the horizontal length of the phone. The height is wrap content, that's fine. My issue right now is that only one button is showing up (stretching across the screen).

Here is my XML code:

<LinearLayout 
   android:id="@+id/page_buttons"
   android:orientation="horizontal"
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:gravity="center_horizontal"

   >
   <Button
        android:id="@+id/prevButton"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Previous"
   /> 

   <Button
        android:id="@+id/nextButton"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Next"
   />

Change your Buttons XML to include the layout_weight attribute:

<Button android:id="@+id/nextButton"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:text="Next"/>
