說明：
ibeacon設備會主動發射藍牙信號，當手機打開藍牙靠近ibeacon設備時，就會收到設備發送的藍牙信號，這時只需要根據ibeacon設備的uuid、major、minor、mac這四個值，就可以確認是哪一臺ibeacon設備，然后調用服務端考勤接口(ibeacon設備只為了確認手機在考勤機邊上，不需要發送考勤數據到ibeacon設備上)，即可實現藍牙考勤。
一、添加靜態權限(在AndroidManifest.xml文件中添加，需要藍牙和定位權限)
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /><uses-permission android:name="android.permission.BLUETOOTH_ADMIN" /><uses-permission android:name="android.permission.BLUETOOTH" />
二、檢測與開啟藍牙、GPS
1.是否支持藍牙：
if (!context.getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH_LE)) { ToastUtils.show("本機不支持藍牙功能, 無法藍牙打卡"); ((Activity) context).finish(); return false; } final BluetoothManager bm = (BluetoothManager) context.getSystemService(Context.BLUETOOTH_SERVICE); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) { mBleAdapter = bm.getAdapter(); //mBleAdapter為全局變量，為BluetoothAdapter對象 } if (bleAdapter == null) { ToastUtils.show("本機不支持低功耗藍牙功能, 無法藍牙打卡"); ((Activity) context).finish(); return false; } return true;2.是否開啟GPS：
LocationManager lm = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);boolean gps = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);boolean network = lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);if (gps || network) { return true;}return false;3.開啟GPS：
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);context.startActivityForResult(intent, ActivityCode.ACTIVITY_CODE_GPS);
4.開啟藍牙：
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);((Activity) mContext).startActivityForResult(enableBtIntent, ActivityCode.ACTIVITY_CODE_OPEN_BLE);
三、動態申請藍牙權限
private boolean check(Context context, String permission) { return ContextCompat.checkSelfPermission(context, permission) == PackageManager.PERMISSION_GRANTED; } /** * 權限申請 */ private void searchBle(){ if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { if (!check(mContext, Manifest.permission.ACCESS_FINE_LOCATION) || !check(mContext, Manifest.permission.ACCESS_COARSE_LOCATION)) { ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION}, ACCESS_LOCATION); } else { //執行藍牙搜索 } } else { //執行藍牙搜索 } } @Override public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { switch (requestCode) { case ACCESS_LOCATION: if (hasAllPermissionsGranted(grantResults)) { //執行藍牙搜索 } else { ToastUtils.show("請開啟權限"); } break; } }四.搜索藍牙
/** * 搜索藍牙*/ public void searchBle() { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) { mBleAdapter.startLeScan(mLeScanCallback); } } /** * 搜索結果回調 */ private BluetoothAdapter.LeScanCallback mLeScanCallback = new BluetoothAdapter.LeScanCallback() { @Override public void onLeScan(final BluetoothDevice device, int rssi, byte[] scanRecord) { //fromScanData方法將ibeacon數據轉換為實體對象，內部包括了uuid、major、minor、mac、distance等信息 final BleUtil.DeviceInfo info = BleUtil.fromScanData(device, rssi, scanRecord); if (info == null || TextUtils.isEmpty(info.uuid) || info.major <= 0 || info.minor <= 0 || TextUtils.isEmpty(info.mac)) { return; } if (mUuids == null || mUuids.isEmpty()) { //此處關閉藍牙搜索 mBleAdapter.stopLeScan(mLeScanCallback); return; } for (MachineInfo machineInfo : mUuids) { if (info.uuid.equalsIgnoreCase(machineInfo.uuid) && (!TextUtils.isEmpty(machineInfo.major) && info.major == Integer.parseInt(machineInfo.major)) && (!TextUtils.isEmpty(machineInfo.minor) && info.minor == Integer.parseInt(machineInfo.minor)) && info.mac.equalsIgnoreCase(machineInfo.mac) && info.distance <= MAX_DISTANCE) { mConnected = true; //回調通知外部，界面更新可考勤狀態 if (mListener != null) { mListener.onConnected(); } //此處是延時調用stopLeScan關閉藍牙搜索 beginTimer(); break; } } } };五、考勤
此步調用服務端提供的API增加考勤記錄
