Android Expandablelistview-上下滚动数据会分散

在我的BaseExpandableListAdapter中，我有类AdapterData的列表。 此AdapterData包含付款类别的日期和对象。 我在适配器中获得每个日期的付款对象。i、 e.3月25日-付款1 3月25日-付款2、3月26日付款3、3月26日付款4、3月26日付款5等。 在我的get group视图方法中，我添加了一些逻辑，比如如果付款数据来自同一日期，那么它应该只属于该日期。 一切都很完美，只有当我向上滚动我的数据时，我的数据才会分散，也就是说，3月26日的记录将在3月25日之前

这是我的密码-

此外，我还尝试了视图的setTag和视图的get tag。
该代码在代码中被注释。
但对我来说什么都不管用

有人能帮我吗？
如果您想了解更多信息，请告诉我。
我猜在设置日期时，这其中有逻辑错误。例如，在这段代码中，如果（currentDate！=DataAdapter.get（groupPosition）.getDate（）{holder.textdate.setVisibility（View.VISIBLE）；dateObj=DateTimeUtils.ConvertunixtTimeStampdate（Long.parseLong）（DataAdapter.get（groupPosition）.getDate（）），DateTimeUtils.DATE_格式_瑞典语）；holder.textdate.setText（dateObj）；currentDate=DataAdapter.get（groupPosition）.getDate（）；}其他{holder.textdate.setVisibility（View.GONE）；}当向上滚动显示日期差异时，它将显示date我猜在设置日期时，这其中有逻辑错误。例如，在这段代码中，如果（currentDate！=DataAdapter.get（groupPosition）.getDate（）{holder.textdate.setVisibility（View.VISIBLE）；dateObj=DateTimeUtils.ConvertUnixtTimeStampdate（Long.parseLong（DataAdapter.get（groupPosition.getDate（）），DateTimeUtils.DATE_FORMAT_SWEDISH）；holder.textdate.setText（dateObj）；currentDate=DataAdapter.get（groupPosition.getDate（）；}否则{holder.textdate.setVisibility（View.GONE）；}当向上滚动时，只要日期不同，就会显示该日期
