添加CompassOverlay并获取错误

Question

我想添加一个compassoverlay，但是我遇到了一些错误：

this.mCompassOverlay = new CompassOverlay(context, new InternalCompassOrientationProvider(context), mMapView);
mMapView.getOverlays().add(this.mCompassOverlay);

无法解析符号'mCompassOverlay' 和 无法解析符号'上下文'

我在哪里获得“符号”？

解决：

Event newEvent = new Event()
{
    Summary = ee[0],
    Start = new EventDateTime()
    {
        DateTime = DateTime.Parse(ee[2] + "T" + ee[3] + ":00+02:00")
    },
    End=new EventDateTime()
    {
        DateTime=DateTime.Parse(ee[4] + "T" + ee[5] + ":00+02:00")
    },
    Location=ee[2],
};
EventsResource.InsertRequest ins = service.Events.Insert(newEvent, nazwa_cal);
Event doins = ins.Execute();
Console.WriteLine("Event created: {0}", doins.HtmlLink);
