android - Xamarin android找不到id字段

我正在Visual Studio 2015中使用xamarin在android上工作。我想添加一个图表，因此为了基本了解，我跟进了oxyplot并下载了文档（示例代码）。现在我只是复制源代码，而是通过编写代码。当我到达FindViewById<PlotView>(Resource.Id)点时，在其中找不到Id字段。为了更好的理解，请参见下面的图片和代码



贝娄是我要复制的代码

using Android.App;
using Android.OS;

using OxyPlot.Xamarin.Android;
using OxyPlot;
using OxyPlot.Axes;
using OxyPlot.Series;

namespace AndroidApp1
{
  [Activity(Label = "AndroidApp1", MainLauncher = true, Icon = "@drawable/icon")]

public class MainActivity : Activity
{
    protected override void OnCreate(Bundle bundle)
    {
        base.OnCreate(bundle);

        // Set our view from the "main" layout resource
        SetContentView(Resource.Layout.Main);

        PlotView view = FindViewById<PlotView>(Resource.Id.plot_view);
        view.Model = CreatePlotModel();
    }

    private PlotModel CreatePlotModel()
    {
        var plotModel = new PlotModel { Title = "OxyPlot Demo" };

        plotModel.Axes.Add(new LinearAxis { Position = AxisPosition.Bottom });
        plotModel.Axes.Add(new LinearAxis { Position = AxisPosition.Left, Maximum = 10, Minimum = 0 });

        var series1 = new LineSeries
        {
            MarkerType = MarkerType.Circle,
            MarkerSize = 4,
            MarkerStroke = OxyColors.White
        };

        series1.Points.Add(new DataPoint(0.0, 6.0));
        series1.Points.Add(new DataPoint(1.4, 2.1));
        series1.Points.Add(new DataPoint(2.0, 4.2));
        series1.Points.Add(new DataPoint(3.3, 2.3));
        series1.Points.Add(new DataPoint(4.7, 7.4));
        series1.Points.Add(new DataPoint(6.0, 6.2));
        series1.Points.Add(new DataPoint(8.9, 8.9));

        plotModel.Series.Add(series1);

        return plotModel;
    }
}}

贝娄是我写的

using Android.App;
using Android.OS;

using OxyPlot.Xamarin.Android;
using OxyPlot;
using OxyPlot.Axes;
using OxyPlot.Series;


namespace SampleChart
{
[Activity(Label = "SampleChart", MainLauncher = true, Icon = "@drawable/icon")]
public class MainActivity : Activity
{
    protected override void OnCreate(Bundle bundle)
    {
        base.OnCreate(bundle);

        // Set our view from the "main" layout resource
        SetContentView (Resource.Layout.Main);
        PlotView view = FindViewById<PlotView>(Resource.Id)
    }
}}

我不知道我在想什么。
任何帮助，将不胜感激

最佳答案

您要访问的ID必须在Xml文件中定义
像这样的东西


  android：id =“ @ + id / Content”


这样您就可以指出具有ID的资源，或者必须在另一个文件中优化它，例如values-> id.xml
