I have the Button defined as follows:

<Button
 android:drawableTop="@drawable/ico"
 android:gravity="center"
 android:id="@+id/StartButton2x2"
 android:text="@string/Widget2x2StartBtnLabel"
 android:layout_width="0dip" 
 android:layout_height="fill_parent"
 android:layout_weight="1" 
 android:background="@drawable/widgetbtn_bg"
/>

The problem is that 'drawableTop' image is aligned to the top border of the Button view. I would like to center it (together with text label) vertically on the button.

'android:gravity' seems to work only on text label. It does not affect 'drawableTop' positioning.

I was able to center it vertically using 'android:paddingTop' - but that does not seem to be a good idea. I guess it would not work properly on different screen resolution/size.
