title: 2x2 Button Grid layout
body: <p>Im trying to create a layout containing a 2x2 grid of buttons (4 total). Ive got the following however it only creates the button grid in the top left. I want the button grid to fill the whole screen.</p>

  &lt;TableRow
      android:id="@+id/tableRow1"

          android:layout_height="fill_parent" /&gt;
  
      &lt;Button
          android:id="@+id/button2"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent" /&gt;
