我如何检测其他信标Android -

Question

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { 
    try {       
     Beacon beacon = new Beacon.Builder() 
       .setId1("2f234454-cf6d-4a0f-adf2-f4911ba9ffa6") // UUID for beacon 
       .setId2("1") // Major for beacon 
       .setId3("5") // Minor for beacon 
       .setManufacturer(0x004C) // Radius Networks.0x0118 Change this for other beacon layouts//0x004C for iPhone 
       .setTxPower(-56) // Power in dB 
       .setDataFields(Arrays.asList(new Long[]{0l})) // Remove this for beacon layouts without d: fields 
       .build(); 
     BeaconParser beaconParser = new BeaconParser() 
       .setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24"); 
     BeaconTransmitter beaconTransmitter = new BeaconTransmitter(getApplicationContext(), beaconParser); 
     beaconTransmitter.startAdvertising(beacon, new AdvertiseCallback() { 
      @Override 
      public void onStartFailure(int errorCode) { 
       Log.e("tag", "Advertisement start failed with code: " + errorCode); 
      } 
      @Override 
      public void onStartSuccess(AdvertiseSettings settingsInEffect) { 
       Log.i("tag", "Advertisement start succeeded."); 
      } 
     }); 
    } 
    catch(Exception o) 
    { 
    } 
} 

我正在使用AltBeacon Library将我的手机变成beacon.I进入我的adb logcat avdertisment开始成功。但是，我想要检测现在充当灯塔的其他电话，我该如何实现这一目标？

用Android Beacon Library检测信标很简单。请参阅本页上的测距示例代码部分：http://altbeacon.github.io/android-beacon-library/samples.html

正如上面链接的示例代码所示，您将在每秒约1次的回调中获得一个可见的所有信标列表，如下所示：

public void didRangeBeaconsInRegion(Collection<Beacon> beacons, Region region) { 
     // The beacons collection contains all beacons detected in the past second 
}
