在AndroidX片段中禁用后退按钮

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    // 获取相关Activity实例
    AppCompatActivity activity = (AppCompatActivity) getActivity();
    
    // 设置空的OnBackPressedCallback对象为回调
    activity.getOnBackPressedDispatcher().addCallback(this, new OnBackPressedCallback(true) {
        @Override
        public void handleOnBackPressed() {
            // 空的回调方法，禁用后退按钮
        }
    });
    
    // Inflate片段的布局
    View view = inflater.inflate(R.layout.fragment_example, container, false);
    
    // 其他视图初始化操作...
    
    return view;
}
