ZoomButtonsController

Kotlin |Java

public class ZoomButtonsController
extends Object implements View.OnTouchListener

java.lang.Object
↳	android.widget.ZoomButtonsController

This class was deprecated in API level 26.
This functionality and UI is better handled with custom views and layouts rather than a dedicated zoom-control widget

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 View.onDetachedFromWindow and from View.onVisibilityChanged when visibility != View.VISIBLE.

Public constructors

ZoomButtonsController

Added in API level 4

public ZoomButtonsController (View ownerView)

Constructor for the ZoomButtonsController.

Public methods

getContainer

Added in API level 4

public ViewGroup getContainer ()

Gets the container that is the parent of the zoom controls.

The client can add other views to this container to link them with the zoom controls.

Returns
`ViewGroup`	The container of the zoom controls. It will be a layout that respects the gravity of a child's layout parameters.

getZoomControls

Added in API level 4

public View getZoomControls ()

Gets the view for the zoom controls.

Returns
`View`	The zoom controls view.

isAutoDismissed

Added in API level 4

public boolean isAutoDismissed ()

Whether the zoom controls will be automatically dismissed after showing.

Returns
`boolean`	Whether the zoom controls will be auto dismissed after showing.

isVisible

Added in API level 4

public boolean isVisible ()

Whether the zoom controls are visible to the user.

Returns
`boolean`	Whether the zoom controls are visible to the user.

setAutoDismissed

Added in API level 4

public void setAutoDismissed (boolean autoDismiss)

Sets whether the zoom controls will be automatically dismissed after showing.

Parameters
`autoDismiss`	`boolean`

setFocusable

Added in API level 4

public void setFocusable (boolean focusable)

Sets whether the zoom controls should be focusable. If the controls are focusable, then trackball and arrow key interactions are possible. Otherwise, only touch interactions are possible.

Parameters
`focusable`	`boolean`: Whether the zoom controls should be focusable.

Added in API level 4

public void setOnZoomListener (ZoomButtonsController.OnZoomListener listener)

Sets the OnZoomListener listener that receives callbacks to zoom.

Parameters
`listener`	`ZoomButtonsController.OnZoomListener`: The listener that will be told to zoom.

setVisible

Added in API level 4

public void setVisible (boolean visible)

Sets whether the zoom controls should be visible to the user.

Parameters
`visible`	`boolean`: Whether the zoom controls should be visible to the user.

setZoomInEnabled

Added in API level 4

public void setZoomInEnabled (boolean enabled)

Whether to enable the zoom in control.

Parameters
`enabled`	`boolean`: Whether to enable the zoom in control.

setZoomOutEnabled

Added in API level 4
