使用此代码…希望它能帮助您
@Override
public void onGroupExpanded(int groupPosition){
//collapse the old expanded group, if not the same
//as new group to expand
if(groupPosition != lastExpandedGroupPosition){
accordion.collapseGroup(lastExpandedGroupPosition);
}
super.onGroupExpanded(groupPosition);
lastExpandedGroupPosition = groupPosition;
}
如果需要默认扩展组,请执行以下操作:
@Override
public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {
View v = super.getGroupView(groupPosition, isExpanded, convertView, parent);
ExpandableListView eLV = (ExpandableListView) parent;
eLV.expandGroup(groupPosition);
return v;
}
那就是使用expandGroup发生了什么事..发生了什么事problem@Pragnaniim fetching中的所有注释都没有展开。请检查logcat中是否存在任何异常或错误。.如果是,请发布。.为什么android:groupIndicator=“@null”?@user2230793,即在thatHI for me函数中隐藏箭头标记图标,工作正常,也获得了提要,但用户界面不仅没有获得提要。在我的XML布局中,我已经有了一个FB墙柱的列表视图。在这个布局中,我在下面有一个可展开的列表视图。如果我按parentgroup text,它将不会扩展到show,因为它已经有了注释。@ManojKumar请花一些时间阅读这两个链接,您一定会得到它。。。。和
