我对这个信标概念很陌生。为了演示目的，我使用此示例应用程序 Android iBeacon App配置了我的一个beacon / estimote。
这里应用程序一次能够找到单个信标。我的意思是我必须传递单个信标的UUID以查找它是否在信标范围内。是否有可能找到多个信标使用相同的应用程序。？我的意思是如果用户输入特定的信标范围，用户应该获得有关特定信标的通知。那么有没有可能添加多个信标..？根据信标的UUID，我必须区分信标的范围。任何人都可以指导任何好的教程或如何对此进行修改。任何帮助将不胜感激..
这是我的 MainActivity.cs

EDIT1： 我尝试了类似这样的操作，当用户进入信标的不同区域时触发通知..但每次同一通知触发两个信标时..i表示每次在用户进入区域时调用ShowNotification（）时，如果用户退出该区域，将调用ShowNotification1（）。
当用户进入其区域时，如何为不同的信标调用不同的通知..？

答案 0 :(得分：1)
通过制作多个区域，可以轻松扩充显示的代码以检测多个信标UUID。
步骤1.除了您拥有的区域外，开始测量其他两个区域
_iBeaconManager.StartRangingBeaconsInRegion(_rangingRegion);
_iBeaconManager.StartRangingBeaconsInRegion(new Region("uuid2", UUID2, null, null));
_iBeaconManager.StartRangingBeaconsInRegion(new Region("uuid3", UUID3, null, null));
您可以对代码进行大量其他更改以监控这些区域，在活动关闭时停止对其进行测距，以查找在每个区域内检测到的多个信标。但所显示的更改将完成您所需的基础知识。
