Since we can't see your code, it's a little tough to answer your question. So let me tell you what works for me: 1. Put something in your layout for the zoom controls: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"; android:layout_width="fill_parent" android:layout_height="fill_parent"> <com.google.android.maps.MapView android:id="@+id/map" android:layout_width="fill_parent" android:layout_height="fill_parent" android:apiKey="NooYawk" android:clickable="true" /> <LinearLayout android:id="@+id/zoom" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" /> </RelativeLayout> 2. Add the actual zoom controls to your container: ViewGroup zoom=(ViewGroup)findViewById(R.id.zoom); zoom.addView(map.getZoomControls()); When I click in the area for the zoom controls (lower left in the example shown above), the controls appear for ~2 seconds, or ~2 seconds after I last interact with them (if I'm actually working the controls). And they reappear the same way. -- Mark Murphy (a Commons Guy) http://commonsware.com Android Training on the Ranch! -- Mar 16-20, 2009 http://www.bignerdranch.com/schedule.shtml --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
