Constructor Detail

SidewaysShoveGestureDetector

public SidewaysShoveGestureDetector(android.content.Context context,
                                    AndroidGesturesManager gesturesManager)

Method Detail

provideHandledTypes

protected java.util.Set<java.lang.Integer> provideHandledTypes()

Specified by:

provideHandledTypes in class ProgressiveGesture<SidewaysShoveGestureDetector.OnSidewaysShoveGestureListener>

analyzeMovement

protected boolean analyzeMovement()

Overrides:

analyzeMovement in class MultiFingerGesture<SidewaysShoveGestureDetector.OnSidewaysShoveGestureListener>

canExecute

protected boolean canExecute(int invokedGestureType)

Overrides:

canExecute in class MultiFingerGesture<SidewaysShoveGestureDetector.OnSidewaysShoveGestureListener>

isSloppyGesture

protected boolean isSloppyGesture()

Description copied from class: MultiFingerGesture

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.

Thanks to Almer Thie (code.almeros.com).

Overrides:

isSloppyGesture in class MultiFingerGesture<SidewaysShoveGestureDetector.OnSidewaysShoveGestureListener>

Returns:

true if we detect sloppy gesture, false otherwise

gestureStopped

protected void gestureStopped()

Overrides:

gestureStopped in class ProgressiveGesture<SidewaysShoveGestureDetector.OnSidewaysShoveGestureListener>

reset

protected void reset()

Overrides:

reset in class MultiFingerGesture<SidewaysShoveGestureDetector.OnSidewaysShoveGestureListener>

getDeltaPixelsSinceStart

public float getDeltaPixelsSinceStart()

Returns horizontal pixel delta change since the start of the gesture.

Returns:

pixels delta change since the start of the gesture

getDeltaPixelSinceLast

public float getDeltaPixelSinceLast()

Returns last horizontal pixel delta change calculated in SidewaysShoveGestureDetector.OnSidewaysShoveGestureListener.onSidewaysShove(SidewaysShoveGestureDetector, float, float).

Returns:

pixels delta change since the last call

getPixelDeltaThreshold

public float getPixelDeltaThreshold()

Get the delta pixel threshold required to qualify it as a sideways shove gesture.

Returns:

delta pixel threshold

setPixelDeltaThreshold

public void setPixelDeltaThreshold(float pixelDeltaThreshold)

Set the delta pixel threshold required to qualify it as a sideways shove gesture.

We encourage to set those values from dimens to accommodate for various screen sizes.

Parameters:

pixelDeltaThreshold - delta threshold

setPixelDeltaThresholdResource

public void setPixelDeltaThresholdResource(int pixelDeltaThresholdDimen)

Set the delta dp threshold required to qualify it as a sideways shove gesture.

Parameters:

pixelDeltaThresholdDimen - delta threshold

getMaxShoveAngle

public float getMaxShoveAngle()

Get the maximum allowed angle between fingers, measured from the vertical line, to qualify it as a sideways shove gesture.

Returns:

maximum allowed angle

setMaxShoveAngle

public void setMaxShoveAngle(float maxShoveAngle)

Set the maximum allowed angle between fingers, measured from the vertical line, to qualify it as a sideways shove gesture.

Parameters:

maxShoveAngle - maximum allowed angle
