unable to swipe down programmatically

[lucky919]

Unable to swipe down programmatically, when i debugged, the 'mSelected' field of ItemTouchHelper is null, thereby the allowedSwipeDirections gets 0 and it returns without swiping the item down.

Hi @lucky919,
You have to allow swipe direction DOWN,
override getAllowedSwipeDirectionsMovementFlags in SwipeableTouchHelperCallback

 public int getAllowedSwipeDirectionsMovementFlags() {
   return ItemTouchHelper.LEFT | ItemTouchHelper.RIGHT | ItemTouchHelper.UP | ItemTouchHelper.DOWN;
  }```

Hi, I've overridden that method, the problem is 'mSelected' field is null, which inturn throws NPE with 'getMovementFlags' method.

@lucky919 I know it's a little late to respond, all you have to do is call the item swipeTouchHelper after overwriting getAllowedSwipeDirectionsMovementFlags , just like that.

itemTouchHelper.swipe(rvInGame.findViewHolderForAdapterPosition(position), ItemTouchHelper.DOWN);

In this case rvInGame is my RecyclerView and position is the current position of the RecyclerView adapter, I get the position from a method I call in a listener of my adapter, as in any RecyclerView with an OnItemClickListener.
