如何将数据集的数据绑定到列表视图？

Question

我已经使用了来自 Web 服务的数据集，我想将数据字段绑定到列表视图中，但我不知道该怎么做，因为我只想从数据集中绑定一些字段，而不是所有字段。 list_adapter 中的布局是我要从数据集中绑定的数据。

这是我的数据集的 Web 方法。

public System.Data.DataSet RequestTxnReceipt(string strIdentity, string strDateFrom, string strDateTo, string strLocIp, string strDomain) {
        object[] results = this.Invoke("RequestTxnReceipt", new object[] {
                    strIdentity,
                    strDateFrom,
                    strDateTo,
                    strLocIp,
                    strDomain});
        return ((System.Data.DataSet)(results[0]));
    }    

数据列表.cs

DataSet ds = ws.RequestTxnReceipt(userName, "", "", "", "");

在您的 adapter.cs 中

添加属性和方法

public List<YourModel> dataSource;

public void AddData(List<YourModel> list)
{
  list.AddRange(list);
  NotifyDataSetChanged();
}

调用方法并将数据集作为参数传递给适配器。

在GetView方法中

public override View GetView(int position, View convertView, ViewGroup parent)
{
    if (convertView == null)
     {
        convertView =LayoutInflater.From(parent.Context).Inflate(Resource.Layout.list_adapter, null);
     }

    YourModel model = dataSource[position] as YourModel;

     //for example , you want to set the text of textview
    TextView view = convertView.FindViewById<TextView >(Resource.Id.transNo);
    view.Text=model.xxx;             

    return convertView;

}
