如何在单体甲状腺的可扩展清单观点上实施点击事件,像这一守则一样,但似乎最有效...... 此外,没有采用IOGroupClickListener方法。

listview.SetOnChildClickListener(new ExpandableListView.IOnChildClickListener()
        {
            public override bool OnChildClick (ExpandableListView parent, View v, int groupPosition, int childPosition, long id)
            {
                return base.OnChildClick (parent, v, groupPosition, childPosition, id);
            }
        });

Answer 1

C# don t 支持诸如 Java等匿名子类,你需要建立一个适当的班级,以实施IOnChildClickListener:

public class MyListener : Java.Lang.Object, ExpandableListView.IOnChildClickListener
{
    public override bool OnChildClick (ExpandableListView parent, View v, int groupPosition, int childPosition, long id)
    {
        return base.OnChildClick (parent, v, groupPosition, childPosition, id);
    }
}

或者,根据你试图做些什么,你可能更好地利用其中一项活动,例如:

ExpandableListView.GroupCollapse
ExpandableListView.GroupExpand
AdapterView.ItemClick
AdapterView.ItemSelected

Just adding the missinge code, which i felt should be there in selected answer

public class MyListener : Java.Lang.Object, ExpandableListView.IOnChildClickListener
{
    public override bool OnChildClick (ExpandableListView parent, View v, int groupPosition, int childPosition, long id)
    {
        return base.OnChildClick (parent, v, groupPosition, childPosition, id);
    }
}

OnCreate 用以下文字补充名单观点的本名听众:

listview.SetOnChildClickListener(new MyListener());
