How to add zoom controls to Android Map View

The following code snippet shows how to add zoom controls to Android MapView. We can achieve this by calling setBuiltInZoomControls(boolean) method.

MapView map = (MapView)findViewById(R.id.mapview);
map.setBuiltInZoomControls(true);

The above code snippet will add the zoom controls to the bottom-center of the MapView. The zoom controls only show up when you touch the screen, so you have to make sure that the map is clickable.

<com.google.android.maps.MapView
       android:layout_width="fill_parent"
       android:layout_height="fill_parent"
       android:id="@+id/mapview"
       android:clickable="true"
       android:apiKey="your key">
</com.google.android.maps.MapView>
