说明：
ibeacon设备会主动发射蓝牙信号，当手机打开蓝牙靠近ibeacon设备时，就会收到设备发送的蓝牙信号，这时只需要根据ibeacon设备的uuid、major、minor、mac这四个值，就可以确认是哪一台ibeacon设备，然后调用服务端考勤接口(ibeacon设备只为了确认手机在考勤机边上，不需要发送考勤数据到ibeacon设备上)，即可实现蓝牙考勤。
一、添加静态权限(在AndroidManifest.xml文件中添加，需要蓝牙和定位权限)
代码语言：javascript复制<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、检测与开启蓝牙、GPS
1.是否支持蓝牙：
代码语言：javascript复制 if (!context.getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH_LE)) {
ToastUtils.show("本机不支持蓝牙功能, 无法蓝牙打卡");
((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为全局变量，为BluetoothAdapter对象
}
if (bleAdapter == null) {
ToastUtils.show("本机不支持低功耗蓝牙功能, 无法蓝牙打卡");
((Activity) context).finish();
return false;
}
return true;2.是否开启GPS：
代码语言：javascript复制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.开启GPS：
代码语言：javascript复制Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
context.startActivityForResult(intent, ActivityCode.ACTIVITY_CODE_GPS);4.开启蓝牙：
代码语言：javascript复制Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
((Activity) mContext).startActivityForResult(enableBtIntent, ActivityCode.ACTIVITY_CODE_OPEN_BLE);三、动态申请蓝牙权限
代码语言：javascript复制private boolean check(Context context, String permission) {
return ContextCompat.checkSelfPermission(context, permission) == PackageManager.PERMISSION_GRANTED;
}
/**
* 权限申请
*/
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 {
//执行蓝牙搜索
}
} else {
//执行蓝牙搜索
}
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case ACCESS_LOCATION:
if (hasAllPermissionsGranted(grantResults)) {
//执行蓝牙搜索
} else {
ToastUtils.show("请开启权限");
}
break;
}
}四.搜索蓝牙
代码语言：javascript复制 /**
* 搜索蓝牙
*/
public void searchBle() {
if (Build.VERSION.SDK_INT = Build.VERSION_CODES.JELLY_BEAN_MR2) {
mBleAdapter.startLeScan(mLeScanCallback);
}
}
/**
* 搜索结果回调
*/
private BluetoothAdapter.LeScanCallback mLeScanCallback = new BluetoothAdapter.LeScanCallback() {
@Override
public void onLeScan(final BluetoothDevice device, int rssi, byte[] scanRecord) {
//fromScanData方法将ibeacon数据转换为实体对象，内部包括了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()) {
//此处关闭蓝牙搜索
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;
//回调通知外部，界面更新可考勤状态
if (mListener != null) {
mListener.onConnected();
}
//此处是延时调用stopLeScan关闭蓝牙搜索
beginTimer();
break;
}
}
}
};五、考勤
此步调用服务端提供的API增加考勤记录
