Android Expandablelistview-关于向上和向下滚动的数据分散

Question

在我的BaseExpandableListAdaptar中，我有类AdaptorData的列表。 此AdaptorData由Date和Object of Payment类组成。 我正在获取适配器中每个日期的Payment对象。即25月3日 - 付款1 3月25日 - 支付2,26 3月3日支付3月26日支付4,26 3月支付5等 在我的获取组视图方法中，我添加了逻辑，如果支付数据来自同一日期，那么它应该仅在该日期之前。 一切都很完美，只有当我向上滚动我的数据时才会分散，那就是26月3日的记录将会在25月3日之前完成。

这是我的代码 -

适配器 -

public class PaymentAdapter extends BaseExpandableListAdapter implemen Filterable {
private LayoutInflater inflater;
private BaseActivity context;
private List<AdaptorData> dataAdaptor;

private List<AdaptorData> mStringFilterList;

    this.context = context;

    inflater = LayoutInflater.from(context);

我已经尝试了[这里]（Android - Expandable ListView - using ViewHolder for optimization）提到的所有方法！和[这里] How ListView's recycling mechanism works）！

另外，我已尝试使用setTag进行查看并获取该视图的标记。 该代码在代码中被注释。 但没有什么对我有用。

任何人都能帮助我吗？ 如果您想了解更多信息，请告诉我。
