问题描述

如何检索在ExpandableListView的OnGroupClickListener中单击的组。

How can I retrieve the group clicked in a OnGroupClickListener of a ExpandableListView.

我已经尝试了parent.getItemAtPosition(groupPosition)并返回组和子项,所以我认为我必须将groupPosition转换为适配器中的绝对位置,但我不知道该怎么做。

I have tried parent.getItemAtPosition(groupPosition) and it return groups and childs so I think I must convert the groupPosition to a absolute position in the adapter, but I don't know how to do it.

new OnGroupClickListener() {

        @Override
        public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {
                Item item= parent.getItemAtPosition(groupPosition);
            return true;
        }
    }


推荐答案

尝试这个:

new OnGroupClickListener() {

    @Override
    public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {

        Object object = parent.getExpandableListAdapter().getGroup(groupPosition);

        ....
        ....

        return true;
    }
}

这应该有效。
