Method Detail

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()

distance

public static float distance(float pos1X,
                             float pos1Y,
                             float pos2X,
                             float pos2Y)

distance

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

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.

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.

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.

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.

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.

hasClicked

public boolean hasClicked()

Check if the event is a click.

Returns:

true it the object was clicked.

hasDoubleTapped

public boolean hasDoubleTapped()

isRelease

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.

getPosition

public float[] getPosition(int index)

Get the transformed pos of the point.

Parameters:

index - point index @see #getPointerCount

Parameters:

index - point index @see #getPointerCount

Returns:

transformed pos of the point.
