我使用的是PinnedSectionListView，它具有标题和子标题的自定义布局。我在这里遇到的问题是所有子布局都附加到第一个标题，而第二个标题没有显示。在我的jsonarray我有2个标题，每个都有单个孩子。我试图调试代码，发现＆＃39; j＆＃39; for循环工作两次而没有进入＆＃39; i＆＃39; for循环。这就是为什么两个子布局都附加到第一个标题的原因。

<强>更新
您尚未在childList新卖家inserting之前清除childs。
试试这个：
................
...........................
childList.clear()
for(int j = 0; j < jarr.length(); j++){
}
.............
......................
