Question

我有一个带有editTextView和TextView的haderListView：当我点击添加图标时，我添加一个List，我可以填充空的editTextView，当我添加2个项目列表时出现问题：当我开始完成第一个列表时，我发现第二个列表采用相同的数据，我如何能够分离每个清单中的项目。

这是第一个List，我把测试放在了fonction中

在附件列表中我发现，它从第一个中获取了数据

我的问题怎么做分离形式？

这是我的适配器：

public class SectionAuthorAdapter extends com.applidium.headerlistview.SectionAdapter {

    private MainActivity mainActivity;
    private Realm realm;
    private Author author = null;
    private Authors_groups authors_groups = null;
    private RealmList<Author> authors = new RealmList<>();
    int num= 0;
    private List<Authors_groups> authors_groupses;

    public SectionAuthorAdapter(MainActivity mainActivity, List<Authors_groups> authors_groupses) {

        this.mainActivity = mainActivity;
        realm = Realm.getInstance(mainActivity);


        this.authors_groupses = authors_groupses;
    }

    @Override
    public int numberOfSections() {
        return authors_groupses.size();
    }

    @Override
    public int numberOfRows(int section)
    {
        if(section == -1)
            section = 0;
        return authors_groupses.get(section).getAuthors().size();
    }

    @Override
    public View getRowView(int section, int row, View convertView, ViewGroup parent) {
        final int id ;
        //ViewHolder holder = null;
        final ViewHolder holder;

        if (convertView == null) {

            holder = new ViewHolder();
            LayoutInflater inflater = mainActivity.getLayoutInflater();
            convertView = inflater.inflate(R.layout.listview_item_agent, null);
            holder.textView1 = (TextView) convertView.findViewById(R.id.textView1);
            holder.editText1 = (EditText) convertView.findViewById(R.id.editText1);


            convertView.setTag(holder);

        } else {

            holder = (ViewHolder) convertView.getTag();
        }
        realm.beginTransaction();

        id = authors_groupses.get(section).getAuthors().get(row).getId();
        authors_groups = new Authors_groups();

         author = authors_groupses.get(section).getAuthors().get(row); 
        if (author != null) {
            holder.textView1.setText(author.getField().getLabel() + " : ");
            if (author.getData() != null && !author.getData().isEmpty())
            {
                holder.editText1.setText(author.getData());
            }
            holder.editText1.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    holder.editText1.getId();
                }
            });


        authors.add(author);
        authors_groups.setAuthors(authors);
        }
        realm.commitTransaction();
        return convertView;
    }

    @Override
    public Object getRowItem(int section, int row) {
        return null;
    }

    @Override

    public View getSectionHeaderView(int section, View convertView, ViewGroup parent) {

        if (convertView == null) {

                convertView = (TextView) mainActivity.getLayoutInflater().inflate(mainActivity.getResources().getLayout(android.R.layout.simple_list_item_1), null);

        }
                section = section+1;
            ((TextView) convertView).setText("Témoin : " +section );

convertView.setBackgroundColor(mainActivity.getResources().getColor(R.color.android_green));


        return convertView;
    }
    @Override
    public boolean hasSectionHeaderView(int section) {
        return true;
    }

    @Override
    public void onRowItemClick(AdapterView<?> parent, View view, int section, int row, long id) {
        super.onRowItemClick(parent, view, section, row, id);

    }

    class ViewHolder {
        TextView textView1;
        EditText editText1;

    }
}

我认为你应该在每次设置适配器之前启动新的适配器。

public class HomeActivity extends AppCompatActivity
        implements NavigationView.OnNavigationItemSelectedListener {
    HorizontalGridView newHorizontalGridView,popularHorizontalGridView,unreleasedHorizontalGridView;
    PopularGridElementAdapter popularAdapter;

    List<UnreleasedImageModel> unreleasedimageModelList = new ArrayList<UnreleasedImageModel>();
    List<NewReleasedImageModel> newreleasedimageModelList = new ArrayList<NewReleasedImageModel>();

    @Override
    protected void onCreate (Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home);

        unreleasedGridElementAdapter = new PopularGridElementAdapter(this, unreleasedimageModelList);
        newReleasedGridElementAdapter = new PopularGridElementAdapter(this, newreleasedimageModelList);

        newHorizontalGridView.setAdapter(newReleasedGridElementAdapter);
        popularHorizontalGridView.setAdapter(popularAdapter);
        unreleasedHorizontalGridView.setAdapter(unreleasedGridElementAdapter);

        parsePopularImages();
        parseUnreleasedImages();
        parseNewReleasedImages();
