Basic animations

You can animate opening from any view to GestureView with gestureView.getPositionAnimator().

To make it possible your should have small "from" view and full screen "to" GestureView, both views should hold same content (image). Once views are ready you can use next methods of PositionAnimator to perform animation.

To start animation call:

enter(View from, boolean withAnimation)
- or -
enter(ViewPosition fromPos, boolean withAnimation)

To exit from GestureView call:

exit(boolean withAnimation)

While GestureView is opened "from" view can be changed (i.e. if notifyDataSetChanged() was called for ListView). In this case you will need to update "from" view:

update(View from)
- or -
update(ViewPosition fromPos)

To check that GestureView is currently opened you may use method:

isLeaving()

Typical usage of this method is next:

@Override
public void onBackPressed() {
    if (!gestureView.getPositionAnimator().isLeaving()) {
        gestureView.getPositionAnimator().exit(true);
    } else {
        super.onBackPressed();
    }
}

In most cases you will need to listen for opening animation state to update other views accordingly. That can be done with:

addPositionUpdateListener(PositionUpdateListener listener)
removePositionUpdateListener(PositionUpdateListener listener)

Animation duration can be set with:

gestureView.getPositionAnimator().setDuration(long duration)
