4. 蓝牙设备扫描
BluetoothAdapter sBluetoothAdapter = BluetoothAdapter.getDefaultAdapter(); // 获取蓝牙适配器
sBluetoothAdapter.isEnabled() // 判断手机蓝牙是否开启
sBluetoothAdapter.enable(); // 尝试开机手机蓝牙
sBluetoothAdapter.startDiscovery(); // 开启扫描蓝牙设备
sBluetoothAdapter.cancelDiscovery(); // 停止扫描蓝牙设备
5. 注册监听蓝牙状态改变的一些通知
public void register() {
LoggerUtils.d(TAG + "register()");
IntentFilter filter = new IntentFilter();
//扫描action
filter.addAction(BluetoothAdapter.ACTION_DISCOVERY_FINISHED);
filter.addAction(BluetoothAdapter.ACTION_DISCOVERY_STARTED);
filter.addAction(BluetoothDevice.ACTION_FOUND);
//配对监听
filter.addAction(BluetoothDevice.ACTION_BOND_STATE_CHANGED);
// filter.addAction(BluetoothAdapter.ACTION_CONNECTION_STATE_CHANGED);
filter.addAction(BluetoothDevice.ACTION_ACL_CONNECTED);
filter.addAction(BluetoothDevice.ACTION_ACL_DISCONNECTED);
filter.addAction(BluetoothA2dp.ACTION_CONNECTION_STATE_CHANGED);//A2dp状态改变
MyApp.getContext().registerReceiver(MYBroadcast, filter);
6. 监听回调
BroadcastReceiver MYBroadcast = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
* 开始扫描
if (action.equals(BluetoothAdapter.ACTION_DISCOVERY_STARTED)) {
if (mDiscoveryListener == null) return;
bluetoothDevices.clear();
LoggerUtils.d(TAG + "ACTION_DISCOVERY_STARTED");
mDiscoveryListener.onScanStart();
* 扫描结束
} else if (action.equals(BluetoothAdapter.ACTION_DISCOVERY_FINISHED)) {
if (mDiscoveryListener == null) return;
mDiscoveryListener.onScanFinish();
discoveryTimes--;
if (bluetoothDevices.size() == 0 && discoveryTimes > 0) {
LoggerUtils.d(TAG + "==================");
startDiscovery(true);
} else {
discoveryTimes = 3;
LoggerUtils.d(TAG + "ACTION_DISCOVERY_FINISHED");
* 发现设备
} else if (action.equals(BluetoothDevice.ACTION_FOUND)) {
if (mDiscoveryListener == null) return;
BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
mDiscoveryListener.onDeviceFound(device);
bluetoothDevices.add(device);
LoggerUtils.d(TAG + "ACTION_FOUND: " + device.getAddress() + "\n" + device.getName());
* 绑定状态改变
} else if (BluetoothDevice.ACTION_BOND_STATE_CHANGED.equals(action)) {//绑定状态监听
BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
if (device.getBondState() == BluetoothDevice.BOND_BONDED) {
connectToDevice();
* 连接状态改变
} else if (action.equals(BluetoothAdapter.ACTION_CONNECTION_STATE_CHANGED)) {
LoggerUtils.d(TAG + "ACTION_CONNECTION_STATE_CHANGED");
* spp连接
} else if (action.equals(BluetoothDevice.ACTION_ACL_CONNECTED)) {
LoggerUtils.d(TAG + "ACTION_ACL_CONNECTED");
* spp断开连接
} else if (action.equals(BluetoothDevice.ACTION_ACL_DISCONNECTED)) {
LoggerUtils.d(TAG + "ACTION_ACL_DISCONNECTED");
* 断开请求
} else if (action.equals(BluetoothDevice.ACTION_ACL_DISCONNECT_REQUESTED)) {
LoggerUtils.d(TAG + "ACTION_ACL_DISCONNECT_REQUESTED");
* A2dp
} else if (action.equals(BluetoothA2dp.ACTION_CONNECTION_STATE_CHANGED)) {
int state = intent.getIntExtra(BluetoothA2dp.EXTRA_STATE, 0);
* A2dp连接成功
if (state == BluetoothA2dp.STATE_CONNECTED) {
if (mBluetoothA2dp == null) return;
mLastBluetoothDevice = sBluetoothDevice;
sBluetoothDevice = getConnectedA2dpDevice(mBluetoothA2dp);
LoggerUtils.d(TAG + "onReceive: " + "A2dp的连接成功");
notifyConnectSuccess();
// if(sJIElIManager != null && sJIElIManager.getFilePathItemList())
* A2dp断开
} else if (state == BluetoothA2dp.STATE_DISCONNECTED) {
LoggerUtils.d(TAG + "onReceive: " + "A2dp断开");
notifyDisconnect();
7. 连接蓝牙
public void connectToDevice() {
LoggerUtils.d(TAG + "connectToDevice()");
if (sBluetoothDevice == null) return;
if (getBluetoothType() == 2) {
LoggerUtils.d(TAG + "杰里蓝牙连接");
switch (sBluetoothDevice.getBondState()) {
case BluetoothDevice.BOND_NONE:
boolean returnValue = createBond();//配对
if (returnValue) {
LoggerUtils.d(TAG + "配对成功");
} else {
LoggerUtils.d(TAG + "配对失败");
break;
case BluetoothDevice.BOND_BONDED:
try {
BluetoothSocket socket = device.createRfcommSocketToServiceRecord(DUUID);
Method method_connect = clazz.getMethod("connect", BluetoothDevice.class);
Boolean BooleanValue = (Boolean) method_connect.invoke(mBluetoothA2dp, mBluetoothDevice);
} catch (Exception e) {
e.printStackTrace();
LoggerUtils.d(TAG + "A2dp连接异常，reason = " + e.getCause());
break;
8. 绑定设备
public boolean createBond() {
try {
Method createBondMethod = BluetoothDevice.class.getMethod("createBond");
Boolean returnValue = (Boolean) createBondMethod.invoke(sBluetoothDevice);
return returnValue;
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
return false;
9, 断开蓝牙
try {
Method method_disconnect = clazz.getMethod("disconnect", BluetoothDevice.class);
Boolean BooleanValue = (Boolean) method_disconnect.invoke(mBluetoothA2dp, mBluetoothDevice);
} catch (Exception e) {
e.printStackTrace();
LoggerUtils.d(TAG + "断开A2dp连接异常，reason = " + e.getMessage());
if (socket != null) {
try {
socket.close();
socket = null;
LoggerUtils.d(TAG + "断开spp socket成功");
} catch (IOException e) {
e.printStackTrace();
LoggerUtils.d(TAG + "断开spp socket异常，reason = " + e.getCause());
10. 解绑定设备
public boolean removeBond() {
try {
Method removeBondMethod = BluetoothDevice.class.getMethod("removeBond");
Boolean returnValue = (Boolean) removeBondMethod.invoke(sBluetoothDevice);
return returnValue.booleanValue();
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
return false;
