Constructor Detail

HoverDrawable

HoverDrawable(View view,
             MotionEvent ev)

Creates a new HoverDrawable for given View, using given MotionEvent.

Parameters:

view - the View to represent.

ev - the MotionEvent to use as down position.

HoverDrawable

HoverDrawable(View view,
             float downY)

Creates a new HoverDrawable for given View, using given MotionEvent.

Parameters:

view - the View to represent.

downY - the y coordinate of the down event.

Method Detail

handleMoveEvent

void handleMoveEvent(MotionEvent ev)

Calculates the new position for this HoverDrawable using given MotionEvent.

Parameters:

ev - the MotionEvent. ev.getActionMasked() should typically equal MotionEvent.ACTION_MOVE.

onScroll

void onScroll(float mobileViewTopY)

Updates the original y position of the view, and calculates the scroll distance.

Parameters:

mobileViewTopY - the top y coordinate of the mobile view this HoverDrawable represents.

isMovingUpwards

boolean isMovingUpwards()

Returns whether the user is currently dragging this HoverDrawable upwards.

Returns:

true if dragging upwards.

getDeltaY

int getDeltaY()

Returns the number of pixels between the original y coordinate of the view, and the current y coordinate. A negative value means this HoverDrawable is moving upwards.

Returns:

the number of pixels.

getTop

int getTop()

Returns the top coordinate of this HoverDrawable.

setTop

void setTop(int top)

Sets the top coordinate of this HoverDrawable.

shift

void shift(int height)

Shifts the original y coordinates of this HoverDrawable {code height} pixels upwards or downwards, depending on the move direction.

Parameters:

height - the number of pixels this HoverDrawable should be moved. Should be positive.
