Answer 1

I have a much simpler solution:

1. Add a button to your row XML, width 0, floating on the right:

>      android:id="@+id/hidden"
>     android:layout_width="0dp"
>     android:layout_height="match_parent"
>     android:layout_alignParentRight = "true">

2. in onChildDraw(), just increase its width by the dX value.

    int position = viewHolder.getAdapterPosition();
    View v = recyclerView.getLayoutManager().findViewByPosition(position);
    Button hidden = v.findViewById(R.id.hidden);
    hidden.setLayoutParams(new LinearLayout.LayoutParams((int)-dX, -1));
   

Make sure not to call the default super.onChildDraw()
