Question

在Expandablelistview中，我想根据子视图中选定的控件更新其中一个groupview图像，如何实现这一点？基本上我想要这样

>>> A = [[1,2],[3,4],[5,6],[7,8],[9,10],[11,12]]
>>> zip(*A)
[(1, 3, 5, 7, 9, 11), (2, 4, 6, 8, 10, 12)]
>>> [list(tuple) for tuple in zip(*A)]
[[1, 3, 5, 7, 9, 11], [2, 4, 6, 8, 10, 12]]

EDIT 下面的代码使我

public View  getChildview(int groupPosition,final int childPosition, boolean isLastChild, View convertView,ViewGroup parent)
{

  View Groupview=parent.getChildAt(groupPosition); ///but gives null when if scrolling the expandablelist

}

Answer 1

我建议使用OnChildClickListener并覆盖onChildClick（）并使用此code获取父视图。

Answer 2

getGroupView() – Returns view for the list group header
getChildView() – Returns view for list child item
So u must create/inflate view in getChildView method
