public View getView(int position, View view, ViewGroup viewGroup) {
        view = wrapped.getView(position, view, viewGroup);
        enableFor(view, position);
        Log.v(TAG, "getView" + position);
        return view;
    }

This is not an issue with the library what so ever. This has to do with the underlying framework and in your view you probably have the width or height of the root view to wrap content which makes Android draw then redraw to continue calculating the bounds with child views. This is more so a question for stack overflow.

Adding a comment for this.

Something similar was happening to me. Also, first half of items were not correctly collapsing when expanding other. After reading this, I've found that the list acts weird if the width and height are not fill_parent (or match_parent) both of them. Maybe will be nice to add a note in the readme.md instructions.
