如何在另一个回收站视图中使用相机和回收站视图？

Question

我是应用程序开发的初学者，我需要帮助或想法，我正在创建一个将通过 ftp 发送的照片应用程序，但我的问题是在 cardview 中查看文件。让我解释。 我有几个卡片视图，它们将根据用户通过 Recyclerview 选择的选项动态添加，在这些卡片中，我们有一个图像视图，他将调用相机并通知要保存在 onActivityResult 中的文件的名称，以及下面我们有 recyclerview，其中每张卡片的图像应与拍摄的照片相对应。 我的问题是如何将此图像添加到相应的回收站视图中。 有可能这样做吗？ 在我的代码下面，对不起，我会在完成后进行重构。

public class PhotoFragment extends AbstractFragment {


private TextView bar;
private DescriptionsPhoto descriptionsPhoto;
private MainAdapter mainAdapter;
private GalleryAdapter galleryAdapter;
private RecyclerView recyclerViewMain, recyclerViewPhoto;
private MaterialButton send;
static final int REQUEST_IMAGE_CAPTURE = 1;

@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = super.onCreateView(inflater, container, savedInstanceState);

    bar = view.findViewById(R.id.text_view_photo);
    recyclerViewMain = view.findViewById(R.id.recycler_view_main);

    send = view.findViewById(R.id.button_send);
    descriptionsPhoto = new DescriptionsPhoto();

    mainAdapter = new MainAdapter();
    recyclerViewMain.setAdapter(mainAdapter);
    recyclerViewMain.setLayoutManager(new LinearLayoutManager(getContext()));

    galleryAdapter = new GalleryAdapter();
    recyclerViewPhoto = view.findViewById(R.id.recycler_view_gallery);
    recyclerViewPhoto.setAdapter(galleryAdapter);
    recyclerViewPhoto.setLayoutManager(new LinearLayoutManager(getContext(),RecyclerView.HORIZONTAL, false ));


    if (getArguments() != null) {
        descriptionsPhoto.setEquip(getArguments().getString("equip"));
        descriptionsPhoto.setOs(getArguments().getString("os"));
        descriptionsPhoto.setUser(getArguments().getString("user"));
    }

    bar.setText(descriptionsPhoto.toString());

    send.setOnClickListener(v -> {
        FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        SendImageFragment sendImageFragment = new SendImageFragment();
        fragmentTransaction.addToBackStack("send");
        fragmentTransaction.replace(R.id.main_frame_layout, sendImageFragment);
        fragmentTransaction.commit();
