Question

當我們想主要和次要的這個代碼，我們在這兩個弄空，但在日誌中我們得到的值：

，當我們想主要和次要使用此代碼，我們得到空在這兩個，但在日誌中我們得到的值：

 Beacon firstBeacon = beacons.iterator().next(); 
     Log.i(TAG,"The first beacon " + firstBeacon.toString() + " is about " + firstBeacon.getDistance() + " meters away."); 
     Log.i(TAG, "The first beacon I see has minor id "+beacons.iterator().next().getId3()); 
     Log.i(TAG, "The first beacon I see has major id "+beacons.iterator().next().getId2()); 

     String minor = beacons.iterator().next().getId3(); 
     String major = beacons.iterator().next().getId2(); 

Answer 1

您可以嘗試

ArrayList<Beacon> mylist = new ArrayList<Beacon>(beacons); 
for (int j = 0; j < mylist.size(); j++) { 
String rangedUUID = mylist.get(j).getId1().toString(); 
String rangedMajor = mylist.get(j).getId2().toString(); 
String rangedMinor = mylist.get(j).getId3().toString(); 
} 

，或者你可以更換該

String minor = beacons.iterator().next().getId3(); 
String major = beacons.iterator().next().getId2(); 

與

String minor = firstBeacon.getId3(); 
String major = firstBeacon.getId2(); 

因爲

beacons.iterator().next()
