Method Detail

distance

public static float distance(float[] pos1,
                             float[] pos2)

getActionMasked

public int getActionMasked()

Return the kind of action being performed. Consider using getActionMasked() and MotionEvent.getActionIndex() to retrieve the separate masked action and pointer index.

Returns:

The action, such as MotionEvent.ACTION_DOWN or the combination of MotionEvent.ACTION_POINTER_DOWN with a shifted pointer index.

getPointerCount

public int getPointerCount()

The number of pointers of data contained in this event. Always >= 1.

Returns:

number of pointers of data contained in this event.

getPosition

public float[] getPosition(int index)

Get the transformed pos of the point.

Parameters:

index - point index @see #getPointerCount

Returns:

transformed pos of the point.

getPosition

public float[] getPosition(int index,
                           float[] dest)

Get the transformed pos of the point.

Parameters:

index - point index @see #getPointerCount

Returns:

transformed pos of the point.

getRawEvent

public android.view.MotionEvent getRawEvent()

getScreenEvent

public TransformedMotionEvent getScreenEvent()

getTransformDifference

@NonNull
public TransformedMotionEvent.TransformDiff getTransformDifference()

Return the differences to the checkpoint. The initial values are (xDiff = 0, yDiff = 0; angleDiff = 0; distanceDiff, scale = 1)

Returns:

a TransformDiff object.

hasClicked

public boolean hasClicked()

Check if the event is a click.

Returns:

true it the object was clicked.

hasDoubleTapped

public boolean hasDoubleTapped()

hasFixedCenterPoint

public boolean hasFixedCenterPoint()

Return if the event has a fixed center point to emulate a multitouch rotating and scaling Event.

Returns:

true if teh event has a fixed center point.

isCheckpoint

public boolean isCheckpoint()

If this return true you must saveImage your current state. The TransformDifference values will be at the start values. (xDiff = 0, yDiff = 0; angleDiff = 0; distanceDiff, scale = 1;)

Returns:

true if this is a checkpoint event.

isRelease

public boolean isRelease()

obtain

public static TransformedMotionEvent obtain(android.view.MotionEvent event)

obtain

public static TransformedMotionEvent obtain(android.view.MotionEvent event,
                                            android.graphics.Matrix matrix)

recycle

public void recycle()

setFixedCenterPoint

public void setFixedCenterPoint(float[] pos)

Set a center point to emulate a multitouch rotating and scaling Event

Parameters:

pos - center point array {x, y}.

setFixedCenterPoint

public void setFixedCenterPoint(float x,
                                float y)

Set a center point to emulate a multitouch rotating and scaling Event

Parameters:

x - center point x.

y - center point y.
