以下是Android平台上使用蓝牙通信的基本代码示例： 1. 首先，需要在AndroidManifest.xml文件中添加蓝牙相关的权限和特性： ```xml <uses-permission android:name="android.permission.BLUETOOTH" /> <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" /> <uses-feature android:name="android.hardware.bluetooth" /> ``` 2. 在Activity或Service中，需要获取BluetoothAdapter实例并进行初始化： ```java private BluetoothAdapter mBluetoothAdapter; ... // 获取BluetoothAdapter实例 mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter(); // 启用蓝牙 if (mBluetoothAdapter == null) { // 设备不支持蓝牙 } else { if (!mBluetoothAdapter.isEnabled()) { mBluetoothAdapter.enable(); } } ``` 3. 扫描其他蓝牙设备： ```java // 开始扫描 mBluetoothAdapter.startDiscovery(); // 注册广播接收器，监听扫描结果 IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_FOUND); registerReceiver(mReceiver, filter); ... // 广播接收器，用于接收扫描结果 private final BroadcastReceiver mReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); if (BluetoothDevice.ACTION_FOUND.equals(action)) { // 获取扫描结果 BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); if (device != null) { // 处理扫描结果 } } } }; ``` 4. 连接其他蓝牙设备： ```java // 获取要连接的设备 BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(address); // 创建Socket并连接 BluetoothSocket socket = device.createRfcommSocketToServiceRecord(MY_UUID); socket.connect(); // 获取输入输出流，进行数据传输 InputStream in = socket.getInputStream(); OutputStream out = socket.getOutputStream(); ... ```
