应用程序使用altbeacon不显示距离

我正在尝试创建和应用程序来定位信标并获得它的距离，我正在使用altbeacon库。通过使用代码我得到附近的灯塔的细节，但我没有得到的距离。这里是我的代码和堆栈跟踪。我的代码中有什么问题，任何人都可以帮助我确定。应用程序使用altbeacon不显示距离

你说“我没有得到距离”。这是什么意思？它为距离打印什么？ – davidgyoung

我的意思是说没有函数setRangeNotifier和addRangeNotifier调用，并且不打印以下日志 Log.d（TAG，“distance：”+ oneBeacon.getDistance（）+“id：”+ oneBeacon.getId1（）+“/ “+ oneBeacon.getId2（）+”/“+ oneBeacon.getId3（））; （标签，“我看到的第一个信标是关于”+ beacons.iterator（）。next（）。getDistance（）+“米远”）; – user2427254

如果我理解正确的问题，问题是，检测和didRangeBeaconsInRegion(...)没有信标永远不会被调用。

尝试更改： setBeaconLayout（“m：2-3 = beac，i：4-19，i：20-21，i：22-23，p：24-24，d：25-25”））;

要使用不同的布局表达式，可能是iBeacon的布局表达式，如果这是您正在尝试检测的布局表达式。你可以从这里找到不同的信标格式表达式的列表：

感谢您的回复，我可以更改beaconLayout和代码工作正常。 – user2427254

嗨大卫我的代码检测到跟随在logcat的

08-04 06:33:33.340: D/BluetoothLeScanner(10057): onScanResult() - ScanResult{mDevice=00:A0:50:B2:94:9B, mScanRecord=ScanRecord [mAdvertiseFlags=6, mServiceUuids=[0000feaa-0000-1000-8000-00805f9b34fb], mManufacturerSpecificData={}, mServiceData={0000feaa-0000-1000-8000-00805f9b34fb=[0, -14, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]}, mTxPowerLevel=-2147483648, mDeviceName=TCZ], mRssi=-84, mTimestampNanos=47410545673859}

所有细节信标和表演，但下面的代码无法正常工作

@Override 
    public void onBeaconServiceConnect() { 

     final Region region = new Region("myBeaons", null, null, null); 

     beaconManager.addRangeNotifier(new RangeNotifier() { 
      @Override 
      public void didRangeBeaconsInRegion(Collection<Beacon> beacons, Region region) { 
       if (beacons.size() > 0) { 
        Log.i(TAG, "The first beacon I see is about "+beacons.iterator().next().getDistance()+" meters away.");   
       } 
      } 
     }); 

     beaconManager.setRangeNotifier(new RangeNotifier() { 
      @Override 
      public void didRangeBeaconsInRegion(Collection<Beacon> beacons, Region arg1) { 

       for(Beacon oneBeacon : beacons) { 
        Log.d(TAG, "distance: " + oneBeacon.getDistance() + " id:" + oneBeacon.getId1() + "/" + oneBeacon.getId2() + "/" + oneBeacon.getId3()); 
       } 
      } 
     }); 

     try { 
      beaconManager.startMonitoringBeaconsInRegion(region); 
     } catch (RemoteException e) { 
      e.printStackTrace(); 
     } 
     try { 
      beaconManager.startRangingBeaconsInRegion(region); 
     } catch (RemoteException e) { 
      e.printStackTrace(); 
     } 

    }

我的主要任务是获得信标设备的距离。
