title: MapView doesn't take up full screen
body: <p>I hate to bother you all again, as this is probably me, a newbie, making some big blunder, but I'm baffled as to why my mapview only takes up a fraction of the screen.  I've been following tutorials.  My layout:</p>
  
  <p><code>
  &lt;?xml version="1.0" encoding="utf-8"?><br>
  <br>
  &lt;RelativeLayout android:id="@+id/RelativeLayout01"<br>
                  android:layout_width="fill_parent"<br>
                  android:layout_height="fill_parent"<br>
                  xmlns:android="http://schemas.android.com/apk/res/android"><br>
                  <br>
    &lt;com.google.android.maps.MapView <br>
          android:id="@+id/mapView"<br>
          android:layout_width="fill_parent"<br>
          android:layout_height="fill_parent"<br>
          android:enabled="true"<br>
          android:clickable="true"<br>
          android:apiKey="MY_API_KEY"<br>
          /><br>
  <br>
  &lt;RelativeLayout><br>
  </code></p>
  
  <p>The specified screen resolution is, as in the droid, 854x480.  It shows up in the emulator in horizontal mode (wide, not very tall).  The map starts about a third of the way from the left and ends about a third of the way from the right.  It starts at the top and ends about a third of the way from the bottom of the screen.  I have no clue why that would happen, as I specified "fill_parent".</p>
  
  <p>Thoughts?</p>
