这里的代码显示了如何将添加数据添加到散列图和可扩展列表视图中。
如您所见，有一个用于可扩展列表视图的哈希图，并且在 adaoter 中，我将标题从 api 重新放置，但是列表视图 parent 的 header 是静态的，并且 [= 中的数据31=] 动态所以你可以看到 diffrance
您添加了很多代码，但我认为这是唯一对您的问题很重要的代码:-
expandableListTitle.add("Today's Task")
expandableListTitle.add("Tommorow's Task")
expandableListTitle.add("Upcoming Task")
expandableListDetail.put(expandableListTitle[0], todaystitle)
expandableListDetail.put(expandableListTitle[1], tommrowtask)
expandableListDetail.put(expandableListTitle[2], upcomingtask)
Log.e("task", expandableListTitle.get(0) + " = " + expandableListDetail.put(expandableListTitle.get(0), todaystitle))
Log.e("task", expandableListTitle.get(1) + " = " + expandableListDetail.put(expandableListTitle.get(1), tommrowtask))
Log.e("task", expandableListTitle.get(2) + " = " + expandableListDetail.put(expandableListTitle.get(2), upcomingtask))
expandableListAdapter = CustomExpandableListAdapter(activity, expandableListTitle, expandableListDetail)
expandableListView!!.setAdapter(expandableListAdapter)
据我从您在 link 中添加的图片了解到，您需要在 [=23] 中显示 child 中存在的元素数量=] 对。
你可以做的就是像这样简单地添加列表中存在的元素总数:-
expandableListTitle.add("Today's Task (${todaystitle.count()})") //.count() gives the total number of elements present in list
它将添加标题为 Today's Task (10) \ here 10 would be the number of elements present in your list。现在你可以简单地以任何你想要的方式格式化

如何获得与 header 中图片所示相同的 child 计数。

这里的代码显示了如何将添加数据添加到散列图和可扩展列表视图中。 如您所见，有一个用于可扩展列表视图的哈希图，并且在 adaoter 中，我将标题从 api 重新放置，但是列表视图 parent 的 header 是静态的，并且 [= 中的数据31=] 动态所以你可以看到 diffrance
您添加了很多代码，但我认为这是唯一对您的问题很重要的代码:-
expandableListTitle.add("Today's Task")
expandableListTitle.add("Tommorow's Task")
expandableListTitle.add("Upcoming Task")
expandableListDetail.put(expandableListTitle[0], todaystitle)
expandableListDetail.put(expandableListTitle[1], tommrowtask)
expandableListDetail.put(expandableListTitle[2], upcomingtask)
Log.e("task", expandableListTitle.get(0) + " = " + expandableListDetail.put(expandableListTitle.get(0), todaystitle))
Log.e("task", expandableListTitle.get(1) + " = " + expandableListDetail.put(expandableListTitle.get(1), tommrowtask))
Log.e("task", expandableListTitle.get(2) + " = " + expandableListDetail.put(expandableListTitle.get(2), upcomingtask))
expandableListAdapter = CustomExpandableListAdapter(activity, expandableListTitle, expandableListDetail)
expandableListView!!.setAdapter(expandableListAdapter)
据我从您在 link 中添加的图片了解到，您需要在 [=23] 中显示 child 中存在的元素数量=] 对。
你可以做的就是像这样简单地添加列表中存在的元素总数:-
expandableListTitle.add("Today's Task (${todaystitle.count()})") //.count() gives the total number of elements present in list
它将添加标题为 Today's Task (10) \ here 10 would be the number of elements present in your list。现在你可以简单地以任何你想要的方式格式化
