Callbacks

Most of the callbacks and configurations are same as for SwipePlaceHolderView. Refer docs

For receiving the directional callbacks for SwipeDirectionalView these annotations are provided.

1. @SwipeOutDirectional: It is called when the item view is either left swiped or top swiped.

@SwipeOutDirectional
private void onSwipeOutDirectional(SwipeDirection direction) {
    Log.d("DEBUG", "SwipeOutDirectional " + direction.name());
}

2. @SwipeInDirectional: It is called when the item view is either right swiped or bottom swiped.

@SwipeInDirectional
private void onSwipeInDirectional(SwipeDirection direction) {
    Log.d("DEBUG", "SwipeInDirectional " + direction.name());
}

3. @SwipingDirection: It is called when the item view is dragging in some direction.

@SwipingDirection
private void onSwipingDirection(SwipeDirection direction) {
    Log.d("DEBUG", "SwipingDirection " + direction.name());
}

4. SwipeTouch: It provides the starting and current touch point's coordinates on the item view while it is getting dragged.

@SwipeTouch
private void onSwipeTouch(float xStart, float yStart, float xCurrent, float yCurrent) {
    Log.d("DEBUG", "onSwipeTouch "
            + " xStart : " + xStart
            + " yStart : " + yStart
            + " xCurrent : " + xCurrent
            + " yCurrent : " + yCurrent
            + " distance : "
            + Math.sqrt(Math.pow(xCurrent - xStart, 2) + (Math.pow(yCurrent - yStart, 2)))
    );
}
