Activity.OnKeyUp(Keycode, KeyEvent) Method

Definition

Namespace:

Android.App

Assembly:

Mono.Android.dll

Called when a key was released and not handled by any of the views inside of the activity.

[Android.Runtime.Register("onKeyUp", "(ILandroid/view/KeyEvent;)Z", "GetOnKeyUp_ILandroid_view_KeyEvent_Handler")]
public virtual bool OnKeyUp(Android.Views.Keycode keyCode, Android.Views.KeyEvent? e);

Parameters

keyCode

Keycode

The value in event.getKeyCode().

e

KeyEvent

Description of the key event.

Returns

Boolean

Return true to prevent this event from being propagated further, or false to indicate that you have not handled this event and it should continue to be propagated.

Implements

OnKeyUp(Keycode, KeyEvent)

Attributes

RegisterAttribute

Remarks

Called when a key was released and not handled by any of the views inside of the activity. So, for example, key presses while the cursor is inside a TextView will not trigger the event (unless it is a navigation to another object) because TextView handles its own key presses.

The default implementation handles KEYCODE_BACK to stop the activity and go back.
