如何从单击listview行的按钮获取对象

当我在ListView上单击一行上的按钮时，我正在尝试存储/获取对象

因此，这是我单击ListView行的代码，该行按预期工作

            //Listview
            ListView mainListView = FindViewById<ListView>(Resource.Id.lstViewMain);

            //Custom adapter (taking a list "allComponents")
            ComponentListViewAdapter adapter = new ComponentListViewAdapter(this, allComponents);
            mainListView.Adapter = adapter;

            //Listview item/row click
            mainListView.ItemClick += MainListView_ItemClick;

但是当我在ListView行上点击按钮时实现了相同的逻辑

            //Edit button
            ImageButton btnEditComponent = FindViewById<ImageButton>(Resource.Id.imgBtnEditComponent);
            btnEditComponent.Click += BtnEditComponent_Click;

我得到错误“System.NullReferenceException:'对象引用未设置为对象的实例”。”

我设法在自定义ListView适配器类中实现了编辑按钮，但我不知道如何访问MainListView\u ItemClick函数中的“AdapterView.ItemClickEventArgs”，以便将对象/组件存储在变量中，就像MainListView\u ItemClick函数中一样，如下所示：

        //Function to show the component's notes
        private void MainListView_ItemClick(object sender, AdapterView.ItemClickEventArgs e)
        {
            //Get the component tapped
            var component = allComponents[(int)e.Id];

这是在自定义ListView适配器类中实现编辑按钮（ListView上的按钮）的两次尝试，我知道如何访问/存储给定行的编辑按钮所在的组件

            //Edit component button
            editComponent = row.FindViewById<ImageButton>(Resource.Id.imgBtnEditComponent);
            editComponent.Click += EditComponent_Click;

尝试2：

            //Set on click listener for the Edit component Button
            editComponent.SetOnClickListener(this);

非常感谢

在适配器的

GetView（）

方法中尝试以下操作：

//Edit component button
editComponent = row.FindViewById<ImageButton>(Resource.Id.imgBtnEditComponent);
editComponent.Tag = position;
//Set on click listener for the Edit component Button
editComponent.SetOnClickListener(this);

        private void EditComponent_Click(object sender, EventArgs e)
        {
            //Get the component tapped
            //This does not work like it does with the ListView row tap function.
            //var component = allComponents[(int)e.Id];

            Toast.MakeText(mContext, e.ToString() + " Edited", ToastLength.Long).Show();
            //Retuns "System.EventArgs Edited"

            //throw new NotImplementedException();
        }

            //Set on click listener for the Edit component Button
            editComponent.SetOnClickListener(this);

        public void OnClick(View v)
        {
            switch (v.Id)
            {
                case Resource.Id.imgBtnEditComponent:

                 //How can I grab the component when the only argument is a View?

                 break;
         }

//Edit component button
editComponent = row.FindViewById<ImageButton>(Resource.Id.imgBtnEditComponent);
editComponent.Tag = position;
//Set on click listener for the Edit component Button
editComponent.SetOnClickListener(this);

public void OnClick(View v)
    {
      int position = （int）v.Tag；
      var component = allComponents[position];
    }
