android - 通过在列表适配器 Android 内单击按钮编辑 EditText

Question

我有一个 ListView 和它下面的一些 EditText。列表中的每一行都有一个编辑按钮，单击该按钮应填充 ListView 下方的编辑文本。现在的问题是我为 ListView 定义了一个自定义适配器。由于我正在扩展 Adapter 类中的布局，而我的 EditText 位于另一个类中，因此如何在单击 ListView 行内的按钮时填充 EditText？

这是我的适配器代码

public class CompleteCommentsAdapter : BaseAdapter 
    {
        private Activities.CommentListActivity commentListActivity;
        private List<Comments> dummyCommentList;
        private TextView txtUserName;
        private TextView txtCommentTime;
        private ImageView imgUserImage;
        private TextView txtCommentText;
        private ImageButton ibtnEdit;
        private ImageButton itbtnDelete;

        public CompleteCommentsAdapter(Activities.CommentListActivity commentListActivity, List<Comments> dummyCommentList)
        {
            // TODO: Complete member initialization
            this.commentListActivity = commentListActivity;
            this.dummyCommentList = dummyCommentList;
        }
        public override int Count
        {
            get { return  dummyCommentList.Count(); }
        }

        public override Java.Lang.Object GetItem(int position)
        {
            return position;
        }

        public override long GetItemId(int position)
        {
            return position;
        }

        public override View GetView(int position, View convertView, ViewGroup parent)
        {
            if (convertView == null)
            {

                convertView = commentListActivity.LayoutInflater.Inflate(Resource.Layout.comment_list_row, null);
                 txtUserName = convertView.FindViewById<TextView>(Resource.Id.txtCommenterName);
            txtCommentTime = convertView.FindViewById<TextView>(Resource.Id.txtCommenterTime);
            imgUserImage = convertView.FindViewById<ImageView>(Resource.Id.imgProfileUserImage);
            txtCommentText = convertView.FindViewById<TextView>(Resource.Id.txtCommentText);
            ibtnEdit = convertView.FindViewById<ImageButton>(Resource.Id.imgBtnEdit);
            itbtnDelete = convertView.FindViewById<ImageButton>(Resource.Id.imgBtnDelete);
            }


            Comments mComments = dummyCommentList.ElementAt(position);

            txtUserName.Text = mComments.UserName;
            txtCommentTime.Text = mComments.CommentTime;



            txtCommentText.Text = mComments.CommentText;
            ibtnEdit.Click += ibtnEdit_Click;
           return convertView;
        }

        void ibtnEdit_Click(object sender, EventArgs e)
        {

        }
    }

如果监听器必须附加到按钮，而不是整行，您可以将对这些编辑文本的引用传递给适配器。或者，您可以在应用程序中构建一个 EventBus，通过不同的类发送单击的文本。
