title: how to show a button in the mapView of an android
body: <p>in my app i am using the view flipper. One side of the flip i have placed some text and edit text view. In the other part of the flip i have the map view.</p>
  
  <p>To flip between these two views i am using the swipe concept. I am able to swipe from the text view to the map view. But to get back to the text page from view i decided to place a button in the in the map view but still, the button is not visible. </p>
  
  <p>Following is my layout of the view flipper</p>
  
  <pre><code>&lt;ViewFlipper android:background="#000000"  android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/viewFlipper1"&gt;
