title: MapView isn't showing up with this?
body: <p>I have this layout in xml. And when I run the activity at the bottom nothing shows up except the buttons.</p>
  
  <pre><code>&lt;LinearLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="fill_parent"
   android:orientation="vertical"
   android:layout_height="fill_parent"&gt;
  &lt;LinearLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="fill_parent"
   android:orientation="horizontal"
  android:layout_height="fill_parent"&gt;
  
  
      &lt;Button
      android:id="@+id/sat"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="Satellite"
      android:onClick="myClickHandler"
      android:padding="8px"/&gt;
      &lt;Button
      android:id="@+id/street"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="Street"
      android:onClick="myClickHandler"
      android:padding="8px"/&gt;
      &lt;Button
      android:id="@+id/traffic"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="Traffic"

      android:layout_height="wrap_content"
      android:text="Normal"
      android:onClick="myClickHandler"
      android:padding="8px"/&gt;
   &lt;/LinearLayout&gt;
  
  &lt;com.google.android.maps.MapView
  android:id="@+id/mapView"

   &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>For some reason the only thingI can see is the buttons at the top. the map doesn't show up when my activity is ran.</p>
  
  <p>Here is my code in the MapActivity also.</p>
  
  <pre><code>public class meeting_map extends MapActivity{
  private MapView mapView;
  
  @Override
  protected void onCreate(Bundle savedInstanceState){
      super.onCreate(savedInstanceState);
      setContentView(R.layout.mapview);
  
      mapView = (MapView)findViewById(R.id.mapView);
      mapView.setBuiltInZoomControls(true);
  }
  public void myClickHandler(View target){
      switch(target.getId()){
      case R.id.sat:
          mapView.setSatellite(true);
          break;
      case R.id.street:
          mapView.setStreetView(true);
          break;
      case R.id.traffic:
          mapView.setTraffic(true);
          break;
      case R.id.normal:
          mapView.setSatellite(false);
          mapView.setTraffic(false);
          mapView.setStreetView(false);
          break;
  
      }
  }
  @Override
    protected boolean isLocationDisplayed(){
      return false;
  }
  @Override
  protected boolean isRouteDisplayed() {
      // TODO Auto-generated method stub
      return false;
  }
  
  
  }
  </code></pre>
  
  <p>Maybe I'm missing something. </p>
