| ↳ | android.widget.ZoomButtonsController |
The ZoomButtonsController handles showing and hiding the zoom
controls and positioning it relative to an owner view. It also gives the
client access to the zoom controls container, allowing for additional
accessory buttons to be shown in the zoom controls window.
Typically, clients should call setVisible(true)
on a touch down or move (no need to call setVisible(false) since it will time out on its own). Also, whenever the
owner cannot be zoomed further, the client should update
setZoomInEnabled(boolean) and setZoomOutEnabled(boolean).
If you are using this with a custom View, please call
setVisible(false) from
onDetachedFromWindow() and from onVisibilityChanged(View, int)
when visibility != View.VISIBLE.
