Constructor Detail

ShoveGestureDetector

public ShoveGestureDetector(android.content.Context context,
                            ShoveGestureDetector.OnShoveGestureListener listener)

Method Detail

handleStartProgressEvent

protected void handleStartProgressEvent(int actionCode,
                                        android.view.MotionEvent event)

Description copied from class: BaseGestureDetector

Called when the current event occurred when NO gesture is in progress yet. The handling in this implementation may set the gesture in progress (via gestureInProgress) or out of progress

Specified by:

handleStartProgressEvent in class TwoFingerGestureDetector

Parameters:

actionCode - Action Code from MotionEvent

event - MotionEvent

handleInProgressEvent

protected void handleInProgressEvent(int actionCode,
                                     android.view.MotionEvent event)

Description copied from class: BaseGestureDetector

Called when the current event occurred when a gesture IS in progress. The handling in this implementation may set the gesture out of progress (via gestureInProgress).

Specified by:

handleInProgressEvent in class TwoFingerGestureDetector

Parameters:

actionCode - Action Code from MotionEvent

event - MotionEvent

resetState

protected void resetState()

Overrides:

resetState in class BaseGestureDetector

updateStateByEvent

protected void updateStateByEvent(android.view.MotionEvent curr)

Overrides:

updateStateByEvent in class TwoFingerGestureDetector

isSloppyGesture

protected boolean isSloppyGesture(android.view.MotionEvent event)

Description copied from class: TwoFingerGestureDetector

Check if we have a sloppy gesture. Sloppy gestures can happen if the edge of the user's hand is touching the screen, for example.

Overrides:

isSloppyGesture in class TwoFingerGestureDetector

Parameters:

event - Motion Event

Returns:

true if is sloppy gesture, false if not

getShovePixelsDelta

public float getShovePixelsDelta()

Return the distance in pixels from the previous shove event to the current event.

Returns:

The current distance in pixels.
