Question

有一个ListAdapter噩梦。我已经阅读了有关如何实例化ListView的所有代码。我绝对将有效TextView的id传递给ListView.Adaptor。

现在代码执行正常并成功地离开了LoadAllStats（）函数和周围的trycatch。然后一切都爆发出意外的停止 - ＆gt;强制关闭对话框。

Logcat表示抛出的异常是ResourcesNotFoundException。它声称文本视图无效，但它绝对是一个textview，我用一个已成功用于其他控件的textview测试它，所以我不知道这到底是怎么回事。

有什么想法吗？（在我粉碎Android手机之前？）

感谢。

namespace Project
{    
    [Activity(Label="History")]
    public class HistoryFileDialog : Activity
    {
        ListView ItemList;
        ADatabase<Stats> Database;
        List<Stats> History;

        protected override void OnCreate(Bundle savedInstanceState)
        {
            base.OnCreate(savedInstanceState);

            SetContentView(Resource.Layout.HistoryWnd);

            ItemList = FindViewById<ListView>(Resource.Id.ListView);
            ItemList.ItemClick += new EventHandler<AdapterView.ItemClickEventArgs>    (ItemList_ItemClick);

        ItemList = FindViewById<ListView>(Resource.Id.ListView);

        string Path = Globals._SDROOT + Globals._PROFILEDIR + "user" + "//progress.profile";
        LoadAllStats(Path);
    }

    private void LoadAllStats(string HistoryDBasePath)
    {
        this.Database = new ADatabase<Stats>(this.ApplicationContext,
            HistoryDBasePath);

        List<Stats> All = Database.ReadAll();
        this.History = new List<Stats>(All.Count);

        string[] Test = new string[] { "work", "you", "goddamn", "list", "adapter" };

        try
        {
   // just some test data for the adaptor.
            ItemList.Adapter = new ArrayAdapter<String>(this, Resource.Id.Output, Test);
        }
        catch (Exception e)
        {
            string Foo = e.StackTrace;
        }
    }
}

}

Answer 1

我的猜测是：

您使用的是标识符ID而不是布局ID

或者

你的resourceid文件以某种方式与java文件不同步。

要测试第一个，请尝试更改ArrayAdapter以使用如下构造函数：

        new ArrayAdapter<string>(this, Resource.Layout.list_item, Test);

尝试测试第二个......

尝试重建所有内容，尝试删除生成的资源设计器cs文件，尝试添加更多控件，尝试在编译器中尖叫等。

使用ArrayAdaptor时的ResourceNotFound异常
