setonkeylistner在我的片段中不起作用

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_layout, container, false);
    
    view.setOnKeyListener(new View.OnKeyListener() {
        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            if (keyCode == KeyEvent.KEYCODE_BACK && event.getAction() == KeyEvent.ACTION_UP) {
                // 处理返回键按下事件
                return true; // 返回true表示已经处理该按键事件
            }
            return false; // 返回false表示未处理该按键事件
        }
    });
    
    return view;
}
