在列表视图项中使用ListViews

Question

我在列表视图的每个元素内使用列表视图。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="@dimen/tiny_paddding"
    >

    <LinearLayout

        <TextView

            android:layout_height="wrap_content"
            android:ellipsize="end"
            android:maxWidth="140dp"
            android:maxLines="1"
            android:text="HelloFriends123" />

    </LinearLayout>

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        <TextView

            android:backgroundTint="@color/red" />

    </LinearLayout>

</RelativeLayout>

因此，对于父级列表中的每个列表项，我都必须为父级列表中的列表创建一个适配器。

public class Document {
    public String documentName;
    public DOCUMENT documentType;
    public boolean multiFile;
    public DocumentUploadListAdapter documentUploadListAdapter;
}

现在的问题是事件，尽管我为每个文档（父项）提供了不同的列表适配器，但我最终还是以相同的列表项结束了。

子列表：

@Data
public class DocumentUploadListAdapter extends BaseAdapter implements Comparable<DocumentUploadListAdapter>{

    public static final String TAG = DocumentUploadListAdapter.class.getSimpleName();

    private List<DocumentUpload> documentUploadList;
    public DOCUMENT documentType;
    private Context context;
    private DocumentUploadListAdapter documentUploadListAdapter;

    private DocumentUploadListClickInterface documentUploadListClickInterface;

    public DocumentUploadListAdapter(){
        super();
        documentUploadListAdapter = this;
    }


    @Override
    public int getCount() {
        if(documentUploadList==null){
            return 0;
        }
        return documentUploadList.size();
    }

    @Override
    public DocumentUpload getItem(int position) {
        return documentUploadList.get(position);
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        View rowView = convertView;
        DocumentUploadListViewModel documentUploadListViewModel = null;
        final DocumentUpload documentUpload = documentUploadList.get(position);
        if(rowView==null){
            LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            documentUploadListViewModel = new DocumentUploadListViewModel();

            rowView = inflater.inflate(R.layout.list_item_upload_document,null);
            documentUploadListViewModel.filedId = rowView.findViewById(R.id.fileId);
            documentUploadListViewModel.fileName = rowView.findViewById(R.id.fileName);

            documentUploadListViewModel.fileUploadButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    if(!documentUpload.isUploaded()){
                        //upload the document here
                        documentUploadListClickInterface.onDocumentUploadListUpload(documentUploadListAdapter, documentUploadList.get(position));
                    }

                }
            });
            documentUploadListViewModel.fileDeleteButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    //check the delete button
                    //needs to checked and the views need to be refreshed
                    documentUploadList.remove(documentUploadList.get(position));
                    notifyDataSetChanged();
                }
            });

            rowView.setTag(documentUploadListViewModel);
        }

        documentUploadListViewModel = (DocumentUploadListViewModel) rowView.getTag();
        documentUploadListViewModel.filedId.setText(documentUpload.getFileId()+"");
        documentUploadListViewModel.fileName.setText(documentUpload.getFileName());

        if(documentUpload.isUploaded()){
            Log.d(TAG, "Image is uplaoded, changing the image");
            documentUploadListViewModel.fileUploadButton.setBackground(getContext().getResources().getDrawable(R.drawable.ic_check_circle, null));
            documentUploadListViewModel.fileUploadButton.setBackgroundTintList(ContextCompat.getColorStateList(getContext(), R.color.green));
            documentUploadListViewModel.fileUploadButton.setEnabled(false);
        }
        else{
            Log.d(TAG, "Reversing, changing the image");
            documentUploadListViewModel.fileUploadButton.setBackground(getContext().getResources().getDrawable(R.drawable.ic_file_upload, null));
            documentUploadListViewModel.fileUploadButton.setBackgroundTintList(ContextCompat.getColorStateList(getContext(), R.color.blue));
            documentUploadListViewModel.fileUploadButton.setEnabled(true);
        }

        return rowView;
    }

    public void addDocumentUpload(DocumentUpload documentUpload){
        if(documentUploadList==null){
            documentUploadList = new ArrayList<>();
        }
        documentUploadList.add(documentUpload);
        this.notifyDataSetChanged();
    }

    public List<DocumentUpload> getDocumentUploadList(){
        return documentUploadList;
    }

    @Override
    public int compareTo(DocumentUploadListAdapter o) {
        if(this.documentType.compareTo(o.documentType) == 0) return 0;
        return 1;
    }

    public class DocumentUploadListViewModel{
        public TextView filedId;
        public TextView fileName;
        public TextView fileUploadButton;
        public TextView fileDeleteButton;
    }

    public interface DocumentUploadListClickInterface{
        void onDocumentUploadListUpload(DocumentUploadListAdapter documentUploadListAdapter, DocumentUpload documentUpload);
    }

}

父母名单：

@Data
public class DocumentListAdapter extends BaseAdapter implements DocumentUploadListAdapter.DocumentUploadListClickInterface {

    public static final String TAG =  DocumentListAdapter.class.getSimpleName();

    private List<Document> documentList;

    private Context context;

    private DocumentListClickInterface documentListClickInterface;

    @Override
    public int getCount() {
        if(documentList==null){
            return 0;
        }
        return documentList.size();
    }

    @Override
    public Document getItem(int position) {
        return documentList.get(position);
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        View rowView = convertView;
        final Document document = documentList.get(position);
        if(rowView==null){
            LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            rowView = inflater.inflate(R.layout.list_item_documents,null);

            DocumentViewHolder documentViewHolder = new DocumentViewHolder();
            documentViewHolder.documentName = rowView.findViewById(R.id.documentName);
            documentViewHolder.documentAdd = rowView.findViewById(R.id.documentAdd);
            documentViewHolder.documentUploadListView = rowView.findViewById(R.id.list_upload_document);
            document.getDocumentUploadListAdapter().setDocumentUploadListClickInterface(this);
            documentViewHolder.documentUploadListView.setAdapter(document.getDocumentUploadListAdapter());

            rowView.setTag(documentViewHolder);
        }

        DocumentViewHolder documentViewHolder = (DocumentViewHolder) rowView.getTag();

        documentViewHolder.documentName.setText(document.getDocumentName());

        documentViewHolder.documentAdd.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(documentListClickInterface!=null) {
                    documentListClickInterface.onDocumentListAddClick(document);
                }
            }
        });


        return rowView;
    }

    public void addDocument(Document document){
        if(documentList==null){
            documentList = new ArrayList<>();
        }
        documentList.add(document);
        notifyDataSetChanged();
    }

    public List<Document> getDocumentList(){
        return documentList;
    }

    @Override
    public void onDocumentUploadListUpload(DocumentUploadListAdapter documentUploadListAdapter, DocumentUpload documentUpload) {
        for(Document document: documentList){
            if(document.getDocumentUploadListAdapter().equals(documentUploadListAdapter)){
                documentListClickInterface.onDocumentUploadListUploadButton(document, documentUpload);
                Log.d(TAG, "Added in: " + documentUploadListAdapter.getDocumentType());
                break;
            }
        }
    }

    public class DocumentViewHolder{
        public TextView documentName;
        public Button documentAdd;
        public ListView documentUploadListView;
    }

    public interface DocumentListClickInterface{
        void onDocumentListAddClick(Document document);
        void onDocumentUploadListUploadButton(Document document, DocumentUpload documentUpload);
    }

}

添加到子级列表：

documentListAdapter - parent List

Document document = new Document();
    document.setDocumentType(documentType);
    document.setDocumentName(documentType.toString());
    if(documentType.equals(DOCUMENT.Account_Statement)){
        document.setMultiFile(true);
    }
    document.setDocumentUploadListAdapter(new DocumentUploadListAdapter());
    document.getDocumentUploadListAdapter().setContext(getContext());
    document.getDocumentUploadListAdapter().setDocumentType(documentType);
    documentListAdapter.addDocument(document);

public void addDocumentUploadInDocumentList(File file){
        if(currentDocument!=null){
            DocumentUpload documentUpload = new DocumentUpload();
            documentUpload.setFile(file);
            documentUpload.setUploaded(false);
            documentUpload.setFileName(file.getName());
            currentDocument.getDocumentUploadListAdapter().addDocumentUpload(documentUpload);
            currentDocument = null;
        }
}
