Draggable views with rotation and skew/scale effects.

1. Implement DragController.IDragViewGroup
2. Create instance of DragController
3. Override onTouchEvent of your ViewGroup and call DragController#onTouchEvent:

@Override public boolean onTouchEvent(MotionEvent event) {
 return dragController.onTouchEvent(event);
}

See full sample at SampleGridContainer
