Remarks

Called when a generic motion event was not handled by any of the views inside of the activity.

Generic motion events describe joystick movements, hover events from mouse or stylus devices, trackpad touches, scroll wheel movements and other motion events not handled by #onTouchEvent(MotionEvent) or #onTrackballEvent(MotionEvent). The MotionEvent#getSource() source of the motion event specifies the class of input that was received. Implementations of this method must examine the bits in the source before processing the event.

Generic motion events with source class android.view.InputDevice#SOURCE_CLASS_POINTER are delivered to the view under the pointer. All other generic motion events are delivered to the focused view.

See View#onGenericMotionEvent(MotionEvent) for an example of how to handle this event.
