android獲取ibeacon列表，供大家參考，具體內容如下

最近公司有需要做ibeacon需求。

因為涉及掃碼的時間。特意寫一個service實現獲取列表可以根據掃描時間掃描出ibeacon列表
包含 uuid,設備名稱，單位（米），電量等。
請根據自己的項目進行改造代碼。

核心代碼如下：

/** * * <ibeaon服務> * * @author fulushan * @date 創建時間：2018年4月5日 下午11:34:04 */public class IbeaconService extends Service {  private static final String TAG = IbeaconService.class.getName();  ArrayList<IBeaconClass.iBeacon> mLeDevices;  private boolean mScanning;  private final static int DATA_COMPLETE = 0;  private final static int DATA_FAIL = 1;  /**搜索BLE終端*/  private BluetoothAdapter mBluetoothAdapter;  // Stops scanning after 10 seconds.  private static long SCAN_PERIOD = 10000;  ResponseResult responseResult = new ResponseResult();  public class IbeaconBinder extends Binder{    public ResponseResult getResponseResult(){      return responseResult;    }  }  @Override  public IBinder onBind(Intent arg0) {    // TODO Auto-generated method stub    return null;  }  @Override  public void onStart(Intent intent, int startId) {    super.onStart(intent, startId);    if (intent != null) {      SCAN_PERIOD = intent.getIntExtra("time",10)*1000;      mLeDevices = new ArrayList<>();      //開啟一個新的線程，如果使用Service，會導致ANR問題，Service本身也會阻塞      new Thread(new IbeaconRunnable()).start();    }  }  @Override  public void onDestroy() {    super.onDestroy();    stopUpdateService();    scanLeDevice(false);  }  class IbeaconRunnable implements Runnable {    Message message = handler.obtainMessage();    public void run() {      try {        //獲取藍牙數據        //開始判斷        // Use this check to determine whether BLE is supported on the device. Then you can        // selectively disable BLE-related features.        if (!getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH_LE)) {          message.what = DATA_FAIL;          responseResult.setStatus(BlueToothEnum.BLU_SERVICE_UNAVAI.getCode());          responseResult.setMsg(BlueToothEnum.BLU_SERVICE_UNAVAI.getMsg());          message.obj = responseResult;          handler.sendMessage(message);          return;        }        if(Build.VERSION.SDK_INT<JELLY_BEAN_MR2){          responseResult.setStatus(BlueToothEnum.BLU_SERVICE_UNAVAI.getCode());          responseResult.setMsg(BlueToothEnum.BLU_SERVICE_UNAVAI.getMsg());          message.obj = responseResult;          handler.sendMessage(message);          return;        }        // Initializes a Bluetooth adapter.

調用方式：

/*** 開啟藍牙服務UpdateService*/  public static void startIbeacon(Context context,int time) {    Intent intent = new Intent(context,IbeaconService.class);    intent.putExtra("time", time);//掃描ibeacon時間    intent.setAction(IBEACON_SERVICE);    intent.setPackage(context.getPackageName());//這里你需要設置你應用的包名    context.startService(intent);  }

其中IBeacon類
