定义广播接收类

		
	private BroadcastReceiver receiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            //这里写需要的业务逻辑
        }
    };		
		
		

注册广播

		
    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater,
                             @Nullable ViewGroup container,
                             @Nullable Bundle savedInstanceState) {

        IntentFilter intentFilter = new IntentFilter();
        intentFilter.addAction("main.screen");
        getActivity().getApplicationContext().registerReceiver(receiver, intentFilter);

        binding = FragmentPictureBookStoryFullscreenBinding.inflate(inflater, container, false);
        return binding.getRoot();
    }		
		
		

广播销毁

		
    @Override
    public void onDestroy() {
        super.onDestroy();
        getActivity().getApplicationContext().unregisterReceiver(receiver);

    }
