Xamarin CrossGeofence 转换

Question

我在这里下载并安装了 xamarin 的 CrossGeofence 插件：https://github.com/domaven/xamarin-plugins/tree/master/Geofence

使用此处找到的样本作为指导： https://github.com/domaven/xamarin-plugins/tree/master/Samples/Geofence

我一直在我的物理机 phone、LGE LG-D852（Android 6.0 - API 23）上进行 USB 调试测试。

我的 CrossGeofenceListener class 已实现，例如：

 public class CrossGeofenceListener : IGeofenceListener
{
    //TODO: figure out what to do with this one.
    public void OnAppStarted()
    {
        //throw new NotImplementedException();
    }        

    //copied from geofence sample
    public void OnError(string error)
    {
        Debug.WriteLine(string.Format("{0} - {1}: {2}", CrossGeofence.Id, "Error", error));
    }

    //TODO: figure out what needs to be done when the location changes.
    public void OnLocationChanged(GeofenceLocation location)
    {
        //throw new NotImplementedException();
    }

    //copied from geofence sample
    public void OnMonitoringStarted(string region)
    {
        Debug.WriteLine(string.Format("{0} - {1}: {2}", CrossGeofence.Id, "Monitoring in region", region));
    }

    //copied from geofence sample
    public void OnMonitoringStopped()
    {
        Debug.WriteLine(string.Format("{0} - {1}", CrossGeofence.Id, "Monitoring stopped for all regions"));            
    }

    //copied from geofence sample
    public void OnMonitoringStopped(string identifier)
    {
        Debug.WriteLine(string.Format("{0} - {1}: {2}", CrossGeofence.Id, "Monitoring stopped in region", identifier));            
    }

    //copied from geofence sample
    public void OnRegionStateChanged(GeofenceResult result)
    {            
        Debug.WriteLine(string.Format("{0} - {1}", CrossGeofence.Id, result.ToString()));
    }
}

我已经创建并开始监控围栏，例如：

 foreach (var facility in Facilities)
        {
            CrossGeofence.Current.StartMonitoring(new GeofenceCircularRegion(facility.Name, facility.Latitude, facility.Longitude, 2000)
            {
                NotifyOnStay = true,
                NotifyOnEntry = true,
                NotifyOnExit = true,
                ShowNotification = true,
                ShowEntryNotification = false,
                ShowExitNotification = false,
                ShowStayNotification = true,
                NotificationStayMessage = "stay message!",
                NotificationEntryMessage = "entry message!",
                NotificationExitMessage = "exit message!",
                StayedInThresholdDuration = TimeSpan.FromSeconds(1),                    
            });
        }

根据以上给出的内容，我只会弹出输入的地理围栏通知。我没有收到退出和停留的过渡通知。关于如何触发停留和退出转换的任何建议？

Answer 1

在用另一个应用欺骗 gps 坐标后，它开始正确报告停留和退出通知。我唯一的假设是，由于 gps 坐标变化不够大，之前没有任何工作。

Answer 2

根据以下代码片段（在您的 post 中描述）：

            ShowEntryNotification = false,
            ShowExitNotification = false,
            ShowStayNotification = true,

您应该会收到 Stay 通知，但不会收到进入/退出通知，为了收到这三个通知，请将正确的 Show...Notification 设置为 true。
