How can RecyclerView ItemTouchHelper lock swipe item?

Question

I use RecyclerView with ItemTouchHelper to do swiping to remove, and add delete button under the swipe item like this:

But when I finish swiping, the item will be removed from the list soon! How can I lock the swiped item, and removed by clicking the delete button? Just like Gmail's behavior.

ps. I post same issues here https://code.google.com/p/android/issues/detail?can=2&start=0&num=100&q=&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars&groupby=&sort=&id=189057

Answer 1

@Override
public void onChildDraw(Canvas c, RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, float dX, float dY, int actionState, boolean isCurrentlyActive) {
    float translationX;
    if(dX > 0){
      translationX = Math.min(-dX, viewHolder.itemView.getWidth() / 2);
    }
    else {
       translationX = Math.max(dX, (-1)* viewHolder.itemView.getWidth() / 2);
    }
    super.onChildDraw(c, recyclerView, viewHolder, translationX, dY, actionState, isCurrentlyActive);
}
