java - 如何在 Android 中获取对等设备的蓝牙名称？

Question

如何获取Bluetoothandroid 设备通过它连接的对等设备的信息（名称、Mac 地址……）Bluetooth？

Answer 1

您可以使用以下代码获取所有远程设备:)

private void discoveryDevice(){
// Register the BroadcastReceiver
IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_FOUND);

    registerReceiver(mReceiver, filter); // Don't forget to unregister during onDestroy

    mBluetoothAdapter.startDiscovery();
}

// Create a BroadcastReceiver for ACTION_FOUND
private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        // When discovery finds a device
        if (BluetoothDevice.ACTION_FOUND.equals(action)) {
            // Get the BluetoothDevice object from the Intent
            BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

            Log.d(TAG, "device " + device.getName() + "\n" + device.getAddress());
        }
    }
};

通过代码获取远程设备的名称对您来说非常有用：

Log.d(TAG, "device " + device.getName() + "\n" + device.getAddress());

我目前无法测试此代码，但也许可以了解如何获取蓝牙的名称和其他参数。

 static BluetoothSocket socket ;
 public static boolean btCon(Context ctx){

 Method m;
 try {
      BluetoothDevice devc = BluetoothAdapter.getDefaultAdapter().getRemoteDevice(MAC_ADRS);

      m = devc.getClass().getMethod("createRfcommSocket", new Class[]{int.class});
      socket = (BluetoothSocket)m.invoke(devc, Integer.valueOf(1));
  socket.connect();

   String name = devc.getName();/* or */ String name2 = devc.getName().toString();
       Log.i("Test","Name: "+name); 
       Log.i("Test","Name 2: "+name2); 

  return true;
 }catch(Exception e)
 {
  return false;
 }
}
