Hi Rob,
That control is essentially an ImageButton that sends onclicks during
a longpresse. Like an ImageButton, you have to supply the background
images:
<ZoomButton android:id="@+id/zoomIn"
android:background="@android:drawable/btn_plus"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<ZoomButton android:id="@+id/zoomOut"
android:background="@android:drawable/btn_minus"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
Unfortunately, it is not a self contained container for zooming.
You would have to handle zooming yourself in the buttons'
OnClickListeners. Without knowing your specific requirements, I'd
recommend extending a View and overriding onDraw. Within onDraw, you
can scale using the supplied Canvas.
Cheers,
James
