如何找到你附近的所有信標（android）？

Question

我需要找到near.I嘗試使用此代碼：https://altbeacon.github.io/android-beacon-library/samples.html 但我收集與零。我使用nRF Connect（來自市場），她向我展示了所有的信標。 我不明白如何設置信標佈局，它是什麼？請幫我

公共類FragmentMain擴展片段實現BeaconConsumer {

FloatingActionButton fabScan; 
RecyclerView recyclerView; 
BeaconListAdapter beaconListAdapter; 
private BeaconManager beaconManager; 
private static final int REQUEST_LOCATION = 1; 
protected static final String TAG = "RangingActivity"; 

@Nullable 
@Override 
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
    View v = inflater.inflate(R.layout.fragment_main, container, false); 
    recyclerView = (RecyclerView) v.findViewById(R.id.rcvBeaconsList); 
    fabScan = (FloatingActionButton) v.findViewById(R.id.fabScan); 
    fabScan.setOnClickListener(onClickListenerScan); 
    beaconListAdapter = new BeaconListAdapter(getActivity());

    recyclerView.setAdapter(beaconListAdapter);

    beaconManager.setForegroundBetweenScanPeriod(1100l);

    beaconManager.bind(this); 
    return v; 

}

        } 
       }); 
      Log.i(TAG, "The first beacon I see is about "+collection.iterator().next().getDistance()+" meters away.");} 
     } 
    });

@Override

@Override

Answer 1

只需修改這一行：

beaconManager = BeaconManager.getInstanceForApplication(getActivity()); 

要添加以下行後：

beaconManager = BeaconManager.getInstanceForApplication(getActivity()); 
beaconManager.getBeaconParsers().add(new BeaconParser(). 
      setBeaconLayout("x,s:0-1=feaa,m:2-2=20,d:3-3,d:4-5,d:6-7,d:8-11,d:12-15")); 
beaconManager.getBeaconParsers().add(new BeaconParser(). 
      setBeaconLayout("s:0-1=feaa,m:2-2=00,p:3-3:-41,i:4-13,i:14-19")); 

我只告訴你如何添加兩個佈局（EDDYSTONE-TLM和EDDYSTONE-UID）。您可能也想添加其他人。你可以看到那些的列表，你可以在這裏補充：

Answer 2

你需要使用一個佈局管理器來肯定。你在使用Eddystone，iBeacon還是什麼樣的信標？我在這裏寫了一個例子，看看它：https://solidgeargroup.com/beacons-on-android
