Constructor Detail

ScaledMotionEventWrapper

public ScaledMotionEventWrapper(android.view.MotionEvent event,
                                float scale,
                                float offsetX,
                                float offsetY)

Method Detail

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.

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.

isCheckpoint

public boolean isCheckpoint()

If this return true you must save 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.

getTransformDifference()

getX

public float getX(int index)

Get the scaled x pos of the point.

Parameters:

index - point index @see #getPointerCount

Returns:

scaled x pos of the point.

getY

public float getY(int index)

Get the scaled y pos of the point.

Parameters:

index - point index @see #getPointerCount

Returns:

scaled y pos of the point.

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.

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.

getTransformDifference

@NonNull
public ScaledMotionEventWrapper.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.
