藍(lán)牙權(quán)限?<uses-permission android:name="android.permission.BLUETOOTH" />

1、監(jiān)聽手機(jī)本身藍(lán)牙狀態(tài)的廣播

手機(jī)藍(lán)牙開啟關(guān)閉時(shí)發(fā)送

action:?BluetoothAdapter.ACTION_STATE_CHANGED

if (action.equals(BluetoothAdapter.ACTION_STATE_CHANGED)) {int state = intent.getIntExtra(BluetoothAdapter.EXTRA_STATE,BluetoothAdapter.ERROR);switch (state) {case BluetoothAdapter.STATE_OFF:Log.d("aaa", "STATE_OFF 手機(jī)藍(lán)牙關(guān)閉");break;case BluetoothAdapter.STATE_TURNING_OFF: Log.d("aaa", "STATE_TURNING_OFF 手機(jī)藍(lán)牙正在關(guān)閉");break;case BluetoothAdapter.STATE_ON:Log.d("aaa", "STATE_ON 手機(jī)藍(lán)牙開啟");break;case BluetoothAdapter.STATE_TURNING_ON:Log.d("aaa", "STATE_TURNING_ON 手機(jī)藍(lán)牙正在開啟");break;} }

2、監(jiān)聽藍(lán)牙設(shè)備配對(duì)狀態(tài)的廣播

藍(lán)牙設(shè)備配對(duì)和解除配對(duì)時(shí)發(fā)送

action:?BluetoothDevice.ACTION_BOND_STATE_CHANGED

if (action.equals(BluetoothDevice.ACTION_BOND_STATE_CHANGED)) {BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);String name = device.getName();Log.d("aaa", "device name: " + name);int state = intent.getIntExtra(BluetoothDevice.EXTRA_BOND_STATE, -1);switch (state) {case BluetoothDevice.BOND_NONE:Log.d("aaa", "BOND_NONE 刪除配對(duì)");break;case BluetoothDevice.BOND_BONDING:Log.d("aaa", "BOND_BONDING 正在配對(duì)");break;case BluetoothDevice.BOND_BONDED:Log.d("aaa", "BOND_BONDED 配對(duì)成功");break;} }

3、監(jiān)聽藍(lán)牙設(shè)備連接和連接斷開的廣播

藍(lán)牙設(shè)備連接上和斷開連接時(shí)發(fā)送, 這兩個(gè)監(jiān)聽的是底層的連接狀態(tài)

action:?BluetoothDevice.ACTION_ACL_CONNECTED ??BluetoothDevice.ACTION_ACL_DISCONNECTED

if (action.equals(BluetoothDevice.ACTION_ACL_CONNECTED)) {BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);Log.d("aaa", device.getName() + " ACTION_ACL_CONNECTED"); } else if (action.equals(BluetoothDevice.ACTION_ACL_DISCONNECTED)) {BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);Log.d("aaa", device.getName() + " ACTION_ACL_DISCONNECTED"); }

BluetoothClass 可以獲取藍(lán)牙設(shè)備的類型

如果想獲取當(dāng)前已連接上的所有藍(lán)牙設(shè)備，可以在這兩個(gè)廣播中手動(dòng)維護(hù)一個(gè)連接設(shè)備的列表。

像下面這樣：

/*** 記錄當(dāng)前正在連接的所有藍(lán)牙輸入設(shè)備*/ public List<BluetoothDevice> connectedBluetoothDevices = new ArrayList<BluetoothDevice>();if (intent.getAction().equals(BluetoothDevice.ACTION_ACL_CONNECTED)) {BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);if (isInputDevice(device)) {List<BluetoothDevice> connectedBluetoothDevices = ((MyApplication) getApplication()).connectedBluetoothDevices;if (!connectedBluetoothDevices.contains(device)) {connectedBluetoothDevices.add(device);}} } else if (intent.getAction().equals(BluetoothDevice.ACTION_ACL_DISCONNECTED)) {BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);if (isInputDevice(device)) {List<BluetoothDevice> connectedBluetoothDevices = ((MyApplication) getApplication()).connectedBluetoothDevices;connectedBluetoothDevices.remove(device);} }/*** 判斷藍(lán)牙設(shè)備是否是輸入設(shè)備,這里認(rèn)為 PERIPHERAL是輸入設(shè)備*/ private boolean isInputDevice(BluetoothDevice device) {int deviceMajorClass = device.getBluetoothClass().getMajorDeviceClass();if (deviceMajorClass == BluetoothClass.Device.Major.PERIPHERAL) {return true;}return false; } 發(fā)一下我寫的 private void registerBoradcastReceiver() { //注冊(cè)監(jiān)聽 getApplication().registerReceiver(stateChangeReceiver, makeFilter()); } private IntentFilter makeFilter() { IntentFilter filter = new IntentFilter(); filter.addAction(BluetoothAdapter.ACTION_STATE_CHANGED); return filter; } private BroadcastReceiver stateChangeReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { Log.d("藍(lán)牙", "" + intent.getAction()); switch (intent.getAction()) { case BluetoothAdapter.ACTION_STATE_CHANGED: int blueState = intent.getIntExtra(BluetoothAdapter.EXTRA_STATE, 0); Log.d("藍(lán)牙", "藍(lán)牙" + blueState); switch (blueState) { case BluetoothAdapter.STATE_TURNING_ON: Log.d("STATE_TURNING_ON", "藍(lán)牙"); break; case BluetoothAdapter.STATE_ON: Log.d("STATE_ON", "藍(lán)牙"); break; case BluetoothAdapter.STATE_TURNING_OFF: Log.d("STATE_TURNING_OFF", "藍(lán)牙"); //藍(lán)牙開關(guān)手動(dòng)關(guān)閉 會(huì)收到這條廣播 break; case BluetoothAdapter.STATE_OFF: Log.d("STATE_OFF", "藍(lán)牙"); break; } break; } } };
