Android - Recycler setOnLongClickListener不工作

Question

我想为RecyclerView设置一个longClick事件，但它似乎不起作用。请注意，当longClicking时，我还需要点击项目的位置（请参阅下面的代码）。这是RecyclerView所在片段的onCreateView中的代码：

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.whitelist, container, false);

    final RecyclerView mRecyclerView = (RecyclerView) rootView.findViewById(R.id.recycler_view);
    mRecyclerView.setLayoutManager(new LinearLayoutManager(Utils.context));

    rcAdapter = new RecyclerAdapter();
    mRecyclerView.setAdapter(rcAdapter);
    mRecyclerView.setItemAnimator(new DefaultItemAnimator());
    mRecyclerView.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
            public boolean onLongClick(View view) {
            final int itemPosition = mRecyclerView.getChildAdapterPosition(view);
            AlertDialog deleteDialog = new AlertDialog.Builder(Utils.context)
                .setTitle(getString(R.string.delete))
                .setMessage(getString(R.string.delete_confirm) + Utils.cInfo.get(itemPosition).name + "?")
                .setIcon(R.drawable.ic_launcher)
                .setPositiveButton(getString(R.string.delete), new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int whichButton) {
                        Utils.cInfo.remove(itemPosition);
                        Utils.convertWhitelistToJSON();
                        rcAdapter.notifyItemRemoved(itemPosition);
                        dialog.dismiss();
                    }
                })
                .setNegativeButton(getString(R.string.cancel), new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.dismiss();
                    }
                })
                .create();
            return true;
        }
    });

    return rootView;
}
