如何实现上下文菜单RecyclerView?显然调用registerForContextMenu(recyclerView)不起作用.我是从片段中调用它的.有没有人有成功实现这个？

}

GestureDetector mGestureDetector;

public RecyclerItemClickListener(Context context, final RecyclerView recyclerView, OnItemClickListener listener) {
    mListener = listener;
    mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
        @Override
        public boolean onSingleTapUp(MotionEvent e) {
            return true;
        }

        @Override
        public void onLongPress(MotionEvent e) {
            View childView = recyclerView.findChildViewUnder(e.getX(), e.getY());

            if (childView != null && mListener != …
