# WindowInsetsAnimationControlListener

`public interface WindowInsetsAnimationControlListener`
``

android.view.WindowInsetsAnimationControlListener

Listener that encapsulates a request to `WindowInsetsController#controlWindowInsetsAnimation`.

Insets can be controlled with the supplied `WindowInsetsAnimationController` from `onReady(WindowInsetsAnimationController, int)` until either `onFinished(WindowInsetsAnimationController)` or `onCancelled(WindowInsetsAnimationController)`.

Once the control over insets is finished or cancelled, it will not be regained until a new request to `WindowInsetsController#controlWindowInsetsAnimation` is made.

The request to control insets can fail immediately. In that case `onCancelled(WindowInsetsAnimationController)` will be invoked without a preceding `onReady(WindowInsetsAnimationController, int)`.

See also:

- `WindowInsetsController.controlWindowInsetsAnimation(int, long, Interpolator, CancellationSignal, WindowInsetsAnimationControlListener)`

## Summary

### Public methods
`abstract void` | `onCancelled(WindowInsetsAnimationController controller)` Called when the request for control over the insets has been cancelled, either because the `CancellationSignal` associated with the `request` has been invoked, or the window has lost control over the insets (e.g.
`abstract void` | `onFinished(WindowInsetsAnimationController controller)` Called when the request for control over the insets has `finished`.
`abstract void` | `onReady(WindowInsetsAnimationController controller, int types)` Called when the animation is ready to be controlled.

## Public methods

### onCancelled

    public abstract void onCancelled (WindowInsetsAnimationController controller)

Called when the request for control over the insets has been cancelled, either because the `CancellationSignal` associated with the `request` has been invoked, or the window has lost control over the insets (e.g. because it lost focus). Once this callback is invoked, the supplied `WindowInsetsAnimationController` is no longer `ready`. Control will not be regained until a new request to `WindowInsetsController#controlWindowInsetsAnimation` is made.

Parameters
`controller` | `WindowInsetsAnimationController`: the controller which has been cancelled, or null if the request was cancelled before `onReady(WindowInsetsAnimationController, int)` was invoked. This value may be `null`.

See also:

- `WindowInsetsAnimationController.isCancelled()`

### onFinished

    public abstract void onFinished (WindowInsetsAnimationController controller)

Called when the request for control over the insets has `finished`. Once this callback is invoked, the supplied `WindowInsetsAnimationController` is no longer `ready`. Control will not be regained until a new request to `WindowInsetsController#controlWindowInsetsAnimation` is made.

Parameters
`controller` | `WindowInsetsAnimationController`: the controller which has finished. This value cannot be `null`.

See also:

- `WindowInsetsAnimationController.isFinished()`

### onReady

    public abstract void onReady (WindowInsetsAnimationController controller,
                    int types)

Called when the animation is ready to be controlled. This may be delayed when the IME needs to redraw because of an `EditorInfo` change, or when the window is starting up.

Parameters
`controller` | `WindowInsetsAnimationController`: The controller to control the inset animation. This value cannot be `null`.
`types` | `int`: The `WindowInsets.Type`s it was able to gain control over. Note that this may be different than the types passed into `WindowInsetsController#controlWindowInsetsAnimation` in case the window wasn't able to gain the controls because it wasn't the IME target or not currently the window that's controlling the system bars. Value is either `0` or a combination of android.view.WindowInsets.Type.STATUS_BARS, android.view.WindowInsets.Type.NAVIGATION_BARS, android.view.WindowInsets.Type.CAPTION_BAR, android.view.WindowInsets.Type.IME, android.view.WindowInsets.Type.WINDOW_DECOR, android.view.WindowInsets.Type.SYSTEM_GESTURES, android.view.WindowInsets.Type.MANDATORY_SYSTEM_GESTURES, android.view.WindowInsets.Type.TAPPABLE_ELEMENT, and android.view.WindowInsets.Type.DISPLAY_CUTOUT
