可扩展的列表视图; onitemClick

我想创建一个可扩展的listview,当用户点击listview(onChildClickListener？)的其中一个项目/子项时,它应该响应.任何人都可以帮助代码吗？我已经做了一个可扩展listview的,我已经制作了自己的适配器和dataprovider类,但我不知道如何编写该onItemClick部件.

您需要为子项和组项设置单独的单击侦听器,如下所示

    expandableListView.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
        @Override
        public boolean onChildClick(ExpandableListView expandableListView, View view,
                                    int groupPosition, int childPosition, long l) {
            Item item = (Item) topicListAdapter.getChild(groupPosition,childPosition);
            handleClick(item);
            return false;
        }
    });
    expandableListView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
        @Override
        public boolean onGroupClick(ExpandableListView expandableListView, View view, int groupPosition, long l) {
            Item item = (item) topicListAdapter.getGroup(groupPosition);
            handleClick(item);
            return false;
        }
    });
